No crank, no start diagnosis (bad block ground) - Ford SHO

[@nutsandbolts7407]

I got my Auto technology book..I went straight to electrical...but ur are the most talented teacher..can't never stop learning from yu

[@northpostman]

Hi Paul, great video. Voltage drop testing is such a fundamental electrical test, and yet is the most under used test in the industry. I am also a college professor, and I push VD testing so heavily on my students, I'm sure they do it in their sleep. Before teaching I was a tech. for 30 years, and I can't count how many times this simple test fixed vehicles that other techs. threw in the towel on. I teach them this method with the test light, and also with a voltmeter. I love your channel, and I use your videos in the classroom.

[@faustogonzalez8397]

northpostman well done buddy, they never taught us this voltage drop test in college, all theoretical, no common applications!! scannerdanner is the man!!

[@roadkill5333]

That's a great example of the simple ground fault issues! Beautiful! I recently found a ground issue on a friends 99 Cherokee. It would skip lightly under moderate or more acceleration, and around left turns with moderate speed. Found a no hold down battery, and a battery negative cable to body ground with a 99.99% broken terminal end. There was still the most minimal connection, and the short length was still pushing against the broken terminal, not pulling away. When the no hold down battery would wobble under movement, it would relieve pressure against the broken terminal, and would cause the skipping. I showed it to my friend, and said that was the cause. He looked UNAMUSED!! I repaired the broken terminal, we took it for a test ride, and the problem disappeared! He was no longer UNAMUSED. I added a hold down, and the problem has completely disappeared! These vids you guys produce (the ERIC TWINS, IVAN THE WONDERFUL, YOUR OWN BROTHER MR JAMES DANNER, and (of course) YOURSELF) are so informational, and entertaining. Thank you so much!

Hands down one of the best videos demonstrating voltage drop.

[@haywardsautomotive6156]

That amazes me how someone can connect a ground wire to a non-metallic surface or an isolated metallic surface consciously & not realize what condition they are creating. That high amp current will find a way to ground & if it finds a low amp ground circuit path it isn't fuse protected...bad news but they should see the smoke before the fire :-) Eric O just did the same test yesterday on a chassis ground using a test light aka scope on a rope & jumper cables & today you covered block grounds using same tried & proven method.... Key is loaded circuit, loaded circuit, loaded circuit!!! Great video Paul & I highly recommend your Premium channel to anyone wanting to learn automotive diagnostics at a bargain price!

[@jacobrobinson175]

I have a 97 Expedition that the previous owner hacked all up and then it's sad for about 2 years and all the braided ground straps were all rotten and corroded and had the main negative going to the block instead of to the starter so I started cleaning up grounds and rust jacking spots and grinding it down to good clean steel and I'll keep you posted when I find out if you're going to fire it up cuz like you said at the almost the end of your video all I get is one loud click from the Bendix not enough continuity for the starter to spin the motor over. Your channel is a great help thank you very much.

[@ScannerDanner]

Thank you!

[@spelunkerd]

The more I think about this the more elegantly simple it becomes. A few ohms of extra resistance will paralyze high current devices, even though most low current circuits do fine. The test light showed the problem but it robbed power from the starter, allowing more current to flow but not enough to turn the armature. Excellent demonstration. Great point about the risk of backfeeding through sensitive electronics.

[@dianapotoski4035]

Excellent SHO ...W! Good Job with diagnosing block ground. (Short Circuit) Im foing through same trying to locate starter ground, ignition. Basics..advice id helpful too

[@jayrockjunk]

Have a 2010 VW Routan(Chrysler). I had the problem of one click, no start. This fix may not fix everyone's but it did mine. It is likely not the starter or the battery. If the starter is clicking then it is not the NSS at all. The NSS prevents the starter from doing anything. So check that off. Switching your gears is NOT fixing the problem. It's only a coincidence that it works after. I have this problem after my first OEM starter blew and a new (re-man) one was put in by dealer and sometime after my trans was replaced/fixed for a whirring problem. This problem went on for several years and slowly got worse. This year.(2020) It would happen everyday and almost everytime I tried to start it. Put 2 starters on it, same thing, battery good, etc. Weird it hardly ever happened in the winter. I'm believing now it's because of the drier weather. Now after watching this video I decided to check the grounds. (kzbin.info/www/bejne/p5W2YoWrZthpfpY). To make this short. I replaced the broken ground strap that is on the passenger side engine compartment that grounds the block to the frame. Mine was broken as you will likely find yours to be. (www.chryslerminivan.net/threads/ground-strap-broken.170175/) Then I removed both cables on the starter (There are 2) and cleaned them with a power drill with wire brush attached. (nice and shiney) Then I removed the eyelet ground wire from the battery to the frame (located inside engine compartment behind drivers side headlight) Cleaned that the same way.(nice and shiney, both eyelet and post). Next do the same for ground wire that screws onto the transmission housing. (power drill, wire brush, bare metal) Tighten up. Clean battery posts too if yours are crappy. Basically, you're just not having a good enough ground to spin that starter. Haven't had the problem since, over 2 weeks now. Problem: One click, no start. Solved: Cleaned ground connections and the "hot" connections to starter.

hi scanner danner i watch your videos everyday to learn something new an i find this one very interesting i am a auto Electrian at Mazda car company in Jamaica you teach me so much please keep doing the good work. thanks far all your information.

[@ScannerDanner]

Thank you!

[@Chrisallengallery]

I had the same problem once. Wouldn't crank sometimes but then be fine for days. It was a ground wire from the top of the block to the starter relay. Only figured it out once I saw the smoke. I had no idea about cars back then and it took me 3 days to find the fix. Proud moment when I fixed my first car.

[@MobyMB24]

I am hoping that is the issue that I'm having. My Mitsubishi Outlander won't start intermittently. Sometimes it does fine, sometimes I can't get it to start for hours or even days. I'm thinking there might be a damaged ground wire somewhere on the starter or something.

[@dgruvers]

I have this problem, no crank once a month. Can jump relay starts right up.

[@hectorserrano4948]

Oh my God , I love this cel phone, I went and changed about 3 starters and nothing, Im goin back to my pick up, Im sure this time it will crank, Thank you man.

[@foreverwood1963]

This is interesting. I had an issue once where my tail lights weren't getting a good ground and I connected my jumper cable from the battery to near the tail gate. I left it running for 20 minutes and when I disconnected the cable it too stayed on, but from this the lights came on without me cleaning a ground for about 3 months. That blew my mind. I started thinking trying to see why. It's like the electrons remained in the metal. I asked everyone had they experienced that no one had until I saw this although this didn't last nearly as long.

[@EXOVCDS]

Back in the 90's, we used to get a lot of cars that would not start after someone changed the clutch... same idea, bad ground at the transmission / block, BUT... the injector driver(s) would fry, because the starter found a ground path through the ECM. Depending on how the driver blew, it would no longer squirt fuel, or the injectors would be stuck open... flooding the cylinders.

[@garylewis3641]

I don't really understand why the test light should not light up, I thought the idea was to get electricity to flow through the engine block back to the negative terminal. Good video!

[@ScannerDanner]

Because voltage potential is 0v on all good grounds. And my test light is connected to battery ground!

[@MrGMATech]

voltage drop testing one of my favorite and the most basic and simple tests to teach :)

[@robertcsims]

This video was helpful. I stumbled across a bad ground recently, thinking it was a bad starter but it was just the ground wire connected to the frame. Once connected to starter, no problem. Would the battery not charge properly with a bad ground to starter or block? The vehicle has charging issues, alternator shows good.

[@faroukkhan6777]

Thanks you sir excellent work,,,stay blessed,, have a great day 👌

[@faustogonzalez8397]

The way I see it Paul, is during starting due to a lack of a solid block ground, the starter cannot source it's 150 amps required for cranking. At that time, it's trying other ground routes for the starter current back to the battery ground. There may be paths available but with the high amperage trying to be conducted the available grounds are dropping to much voltage and the starter is getting less than the minimum required approximately 10 VDC. Once the car is started, the remaining power circuits required for ignition, etc have ground routes available that do not draw high amperage and are satisfied providing ground paths for these ignition/computer/sensor circuits that are required for the engine to run? Thanks Paul.

Hi ScannerDanner I notice you mentioning the braided strap. can you clarify the difference between what I am familiar with as a "BONDING STRAP" to an actual Ground. I think your viewers would appreciate the explanation.

[@tocsa120ls]

Nice video. I have seen older cars run with the engine grounding out only on the throttle linkage :-)

[@francisScrnName]

Thanks ScannerDanner for the bad block ground diagnosis, very helpful

[@OrbiterElectronics]

Can't believe the garage couldn't carry out that simple test themselves. As an ex Nissan technician & foreman I would expect every mechanic to know those basics, even the apprentices.

[@LynxStarAuto]

One of the most common mistakes in the industry. I have gotten dozens of no start/hard start/stall no start conditions, and in most cases a bad ground being the culprit. I see it way too often with body shop cars.

[@andrewwmacfadyen6958]

Very common but not always due to error sometimes the cables just break, the old style earth braids were more flexible --- if called out to a no crank no start a jump a cable engine or gearbox to battery negative was always the first quick and diry test. Increasing even finding a good ground on the engine to hook up the jumper cable is becoming more difficult,

[@ScannerDanner]

In this garages defense. They realized their mistake but allowed me to film it.

[@LynxStarAuto]

ScannerDanner An honest mistake. Lord knows I have committed my fair share.

[@andrewwmacfadyen6958]

Yes often block grounds aren't in obvious places. For anybody building or restoring a car it is a good idea to locate the grounds in a visible place, or even run an extra ground strap between engine and body.

[@stevencsawyerss]

Need to change my negative batt cable, works ok it's just old. I have a nice new cable, I just need to track the old cable to see where it's grouded to. I have a 96 Ford F-150 with a 5.0 V8. I wished I could afford some diagnostic tools, like the ones you have.

[@-bro7453]

good old tale my father would say. what are the 3 things you need to start an engine. spark.fuel,compression and when looking into electronics. BV,CV and EV. is all u need to know

[@Ottonic6]

Thank you so much! I believe this just confirmed that I have a bad block ground. Cause there are times when I try to start my car (battery charged w/good clean connections) I get no crank. But as soon as I hook the jumper cables, it starts right up. Funny thing is on a normal temperature day it will start on its own. When it is real cold or hot outside sometimes I will turn the key and it will take a second or two before it cranks and starts, or I have to turn the key two or more times before I get my crank. Someone said it was my starter or ignition switch, but the fact it starts right up with my jumper voids that suggestion (plus, I did have my starter go bad and it was replaced) I have also gotten a new battery (twice). Like you stated in this video, I think the reason it starts on normal temp days is it is finding some alternate way to ground, then on the hot or cold days it can't get that ground... I will watch your other videos then run some test to confirm this. S.D. Thanks again!

[@RC-Heli835]

Only trained mechanics would expect to see a test light light up touching an engine block that has a bad ground with the test light hooked to ground. Ive been around mechanicing for a long time and have never come across this particular situation. This is one of those wow! Moments for me. I have come across a 24 V alternator on a bulldozer not charging because some one lost the insulator washer at the alternator to battery term. After much head scratching I found it because the eye on the red lead going from the alternator to the battery had turned glowing red. I'm still not exactly sure how a direct short like that on a 24 v system did not instantly burn the wire in half maybe there was a protection circuit in there somewhere..

[@andrewwmacfadyen6958]

In the old days when cars still had carbs with manually operated chokes we used to see old style BL Minis where a lower engine mount would fail and would be only restrained by the block ground. Eventually the extra strain would break the block ground braid and the customer would complain that the car was very slow to crank and smoke was coming from the dash as the engine grounded through the choke and throttle cables.

[@ScannerDanner]

That's crazy! And awesome at the same time!

[@pcno2832]

It's easy to ignore floppy engine mounts, but they can really wreck havoc. My '92 Dodge Monaco (near-Renault 25) had a cracked fuel line, then all the transmission fluid leaked out a hole in the side of the casing, at which point I caught on and replaced all the mounts. More recently, I went to visit my sister and brother-in-law and complained that their VW was so loud I couldn't hear them talking. Turned out everything was going wrong at once, including electrical glitches and exhaust leaks; I suggested they look at the engine, transmission and subframe mounts. They were all bad, but the car was too far gone.

[@fixitman8028]

Paul. Thanks for the great example with test light and jumper wire. I am a premium subscriber and have learned a tremendous amount from your video’s. Quick question on body grounds. I have a 05 Caravan with a corroded G101 ground stud. The stud snapped when attempting to remove the corroded nut. No problem though I drilled a 1/4 hole next to it and reattached the ground eyelit there. If I run an additional wire attached to the ground stud to batt negative do you foresee any problems? I am thinking more paths to ground the better. Just curious in case I am somehow bypassing chassis ground system. Thanks for all your help and explanations.

Working on a chrysler at the moment. Where would 150mV come from on the block? And would that be enough to mess up a tcm which is grounded on the block? Already replaced the alternator which tested bad. After replacing the alternator, the block voltage (and tcm ground) dropped to 90mV.

[@ratbag359]

When I see this it makes me want to check the other ground in particular the engine to body and body to battery as those wires and connections are only rated for vehicle loads usually around 50Amp max. I have also seen systems where they go battery - body - engine they seem to be the worst for bad grounds due to corrosion on the body where the wire is fastened.

[@turenolevin4672]

awsome test for bad ground. subscribed your channel.

[@michaelsabella5924]

I find using this test light a little confusing, wouldn't it be easier, just my opinion, to use an Ohm meter to check for resistance between the neg batt connector and ANY metal surface that should be connected to engine ground. Of course this may cost more with the need of a multimeter - digital is the best... Food for thought -

[@ScannerDanner]

And NO, the ohmmeter is THE WORST tool for this situation. I have a few videos to show where a high resistance circuit can show perfect resistance when tested with an ohmmeter. In short, it does not stress the circuit. Watch this one. Move to near the end of the video where I show the ohm tests kzbin.info/www/bejne/amXHgWmOaLaGa6M

I wonder if an LED test light would have actually worked in this instance or not! The voltage differential was opposite of what it should have been when you loaded up the block, and since LEDs can only pass current in one direction, I'm not sure we would have seen it function the same way your incandescent did.

[@teardowndan5364]

I'd go with grounding through the transmission as the most likely path: with the vehicle stopped, there is no torque on the gears to keep contact between them and no thrust on the input shaft (from meshing with gears) to make solid contact through the bearings.

[@carslover3509]

I have a question: Whenever I go through a car wash or have my truck outdoors in heavy rain at an angle (back end of the truck higher than the engine on a sloped driveway), my engine gets grounded. Clicks but no crank and starts draining the battery. Been trying to track this issue but no luck. Is it really as simple as Battery Negative to Engine block ground?

Hey Paul. Surely this problem is weird; how do I get directed towards a bad ground with a no crank problem? Because I would be like checking the starting system.

[@Blazer02LS]

Usually there will be a few indications that show a bad ground. Plus one of the first things to check in any no-start are the power and grounds, especially in the rust belt.

You would find this through voltage drop testing of the starting system. 12v around about at battery. A lot less at starter then checking for either positive cable or ground voltage drops, all while loading (cranking) the starter system. Pauls way with the test light though is a very quick and simple way to check the ground integrity of the starter system. Hope that helps.

+Kirk Abrahamson got it, thanks people. Fortunately I don't worry about rust too much in the tropic ;)

my lincoln has the negative terminal to the motor and the posative to the starter just like this car! i switched them around and when i hooked it to the battery the black terminal caused a big spark like little fire crackers thrown on the ground. so i switched them back and now car starts up fine. what should i really do in this situation??

You intentionally bolted your battery positive terminal to the block?
