You, dear Sir, are a Godsend!! Your video saved me potentially hundreds of hours of banging my head against a wall trying to chase down the crazy symptoms I was having with my caddy (exactly the same symptoms You were describing). Thank You soooo much for sharing Your wisdom and hard work!! I would have NEVER thought to look at the (completely obscured by other things) block grounding cable. Mine was completely severed right at the crimped eyelet that mounts to the block. Thank You again for Your incredibly helpful video!!!!

After watching a ridiculous amount of this dudes video's, I was trying to test my speinter starter motor for a no crank under the advise that it was that from a garage doing its yearly test, and i noticed the earth strap was black. Sobturning my attention to it, I moved it about and then went to try again and the thing cranked. Mr Scannerdanner you rock. Im an avid fan. Keep the vids coming, i'm hooked.

Hi, Paul. I've got about 30 years as a diagnostic tech. I hate to seem like a tool salesman, but, Power Probe 3 is a huge time saver. it is a dvom with really long leads. Direct battery hookup can tell you what the battery voltage is and voltage drop on both power and ground sides. I quickly diagnose all makes for a no crank problem. You check 3 things at the starter. Voltage at the + terminal, voltage at the crank signal wire and voltage at the case ground. All while cranking. Loading the circuit is key as you stated. I'm not trying to brag but your Cadillac would have been diagnosed within 2 minutes or so. I learned this the hard way though the years. Now I teach this to all new techs. The Power Probe 3 is a great tool. Yes you can do it with a dvom and test light and long jumper wires. But the Power Probe 3 is all those in one. I tried and quickly returned the Power Probe Hook. Don't waste your time and money on that one. The Power Probe 3 will quickly pay for itself if you make money fixing cars and learn to use the tool. I love your videos and your teaching methods. You're doing great work for future and current techs including myself. Big thanks from Marina Del Rey, California.

Kudos for exposing your human side, teacher. Watched this video in its entirety because I just inherited my mother's car identical to yours including dead battery. It made me smile to remember the first time I learned to jerry-rig an extra ground wire. It was in the '60s .. when I was 18.. and I found it myself. If I had videos like yours then.. then the space-time continuum would have been altered, of course!

My exact problem I'm witnessing right now today exact same symptoms and voltage readings, fuel pump running continuously, no scanner communication...I did all same test you did, I was suspecting bad ground all ready but the 2 volts at fuse box was making me look elsewhere and totally threw me off and started thinking bad positive lead wire, I thought maybe anti-theft was causing all this also, trying different keys and such, I even started thinking my volt meter leads were shorting out because of the crazy random numbers I were getting, but like you said a bad ground makes sense if you really think about it, this definitely was a head scratcher, thanks for video I'm going straight to that ground wire when I get back to vehicle, this video was right on time!

What I find with certain professionals is this, those that LOVE their craft will always tend to work hard at it. You love what you do and it shows. I'm medical but I've been watching your videos for years. I'm pretty anal when it comes to learning I have to know things inside out. This video really helped me. I've done some voltage drop testing before and for some reason sometimes I forget to load the circuit. Anyway I have a 1961 Chevy Apache that I'm working on and the tail lights have from time to time given me trouble. At one point I found a frayed power to the tail lights grounding out. I showed full voltage at the tailgate. I bought a new harness really two new harnesses since they divide at the door then at the bumper. Fast forward 3 years up until now it worked perfectly. I go out and the tail lights aren't working. I like to use the Power Probe since its so long although I've seen situations where if I had a regular voltmeter with long leads it would be better. I have trouble trying to do voltage drop with the power probe. Anyway I found full voltage at the tailgate itself when I turn on the lights. The tag light would work. but not the tail lights. I started thinking because of a video I had seen once that stressed power attempts to go to ground and it really doesn't matter if it goes through the ground side to get there. If I take a jumper from the battery to the back and touch the tail gate the lights turn on. Sounds simple but I was still wondering if some rodent ate through a wire and it was touching ground. The problem is there was no blown fuses. I disconnected the harness at the door and sent power back towards the tail lights without adding the additional ground and no lights only the tag light. I then disconnected at the tail gate and sent power through this is all with the power probe again the same. I kept saying it must only be a bad ground but of course unlike today's cars there was no ground all over the place back then. I now said to myself this has to be the reason sometimes that the engine wouldn't even turn over. If I went out and took a screwdriver and jumped it manually at the starter it would jump then the ignition key would always work afterwards unless I let it sit for months. When you showed the 10 volts at the ground side I said bingo!! If I had long lead for my voltmeter I would've done voltage drop on the ground side I quickly found the issue I think. The power probe says it does voltage drop I need to delve a little deeper. Thanks for the video however simple it appears it was excellent. I think like Netflix You Tube should allow us to like dislike or love the video. This video I love

Larry Hurst In short, the PCM was all screwed up (among many other modules) with incorrect voltage levels through the entire board. It is not a stretch for a particular transistor to be energized when it shouldn't be. Either from a misinterpreted RPM signal that really didn't exist (input side problem) or just simply the output driver itself turning on from a messed up voltage level at the base circuit.

As an auto electrical mechanic(which I learned literally everything from you),the first thing I do,is hookup a 20 foot red and black corded jumper wires to the battery and use them as my power and ground source.

Hi Paul thanks for the video, would a powerprobe hook come in handy for finding this type of fault?

A test light glowing when connecting frame and engine is such an impressive demonstration, I'll never forget it again. It's a rabbit out of a hat. I don't have many tricks when working up seemingly complicated problems but bad grounds are a fast way to look like a genius, ha ha.

I'm checking out your video cause I have an 2003 with intermittent starting issues. When the car is shutoff and heats up after 5 or 10 minutes it won't start, click, click, click. When it's cold it always starts never an issue? We checked the battery the alternator and it has a new starter so this video gave me somewhere to go, the engine ground and or the CPU ground. Thanks
