[@FastEddie007007]

Since I am an old school guy as soon as I knew one battery was out of the circuit I would have brought out the jumper cables for trial and error work to get everything working. In this case I would made the repair with a heavy duty ground strap from the engine to the frame. Probably the way your dad would have done it. All cars and trucks should have an engine to frame ground strap and a body to frame strap to ensure a consistent ground. I am 71 years old and like your dad I grew up in a time when we didn't have much to work with. We just think a little differently. I do enjoy watching your brain work with logic of the computerized systems we have today. You make it look easy and it probably is when you have the wiring diagrams available and the scan tools you have. You are at a level not many mechanics will ever achieve. Keep up the good videos and I will keep watching.

[@putsowetmefdupa1]

The presentation was for mechanics that did not have a strong understanding of electrical troubleshooting

[@stephensaines7100]

I'm an electronic tech, and the second thing I'd check after battery voltage, and finding a differential, is measure the resistance between battery terminals, neg to neg, pos to pos. If you're measuring a different voltage across two devices that are in parallel, then they're not truly in parallel. Something ain't right. Also, as a tech, 'chassis grounds' in any device, unless silver or gold plated, (copper can work but not as well) are problematic when using them to conduct hundreds of amps as needed to crank the engine. Always connect a healthy gauge of copper wire between those terminals with a common ground at the starter via the same heavy gauge wire. And equal gauge from the solenoid back to the batteries. Wire is cheap in the big scheme of things. Always wire directly for ground returns on high current devices.

[@beechwood619]

I made my "bad ground" diagnosis at the point in the video when you didn't get the same voltage reading from each individual battery, that was the give away as to the problem for me. I have watched most of your videos and have learned a lot. I didn't cheat by watching the entire video and then composing my comment.

[@patricksmith5655]

Alternator charges batteries, batteries crank engine, engine running, alternator runs lights,all accessories, and plow motor also plow lights. The only GROUND between the alternator and ALL of the above is the connection that you found FRIED. Ground for the plow is going back to the Neg. Battery terminal NOT the ENGINE BLOCK. Remember the Plow is AFTER-MARKET, Ford doesn't know its there and the Plow manufacture doesn't know its installed on that Ford so all they can do is rig it to ground to the battery. Answer is an extra ground cable from the alternator mounting bolt to the plow motor.

[@leocurious9919]

The battery saw the alternator voltage, so no, the alternator was fine, its connected to the battery. The only problem was the ground of the "second" battery never reached that of the still working battery at the chassis. See 29:00

This was a great video, Eric. I appreciate your taking us on this learning journey. The proof of concept technique was the extra step but also informative. These “teaching moments” (and the humor) is what keeps me coming back for more. Oh, and I loved the drawing on Scotty too.

[@Roger-pw3zz]

Sometimes a continuity (resistance) check is a better approach than voltage. Either points you toward a fix, but if it was me and I knew that the batteries were truly connected in parallel I'd: Check resistance between the (+) battery terminals (should be near zero Ohms) Check resistance between the (-) battery terminals (should be near zero Ohms) The second test fails in this situation, so: Check resistance of each battery's negative terminal to chassis. The defective chassis ground of the offending battery would immediately be apparent. Nice post. I admire the energy and effort that you put into this channel.

[@davidtyndall9604]

Eric, as soon as you drew your wiring diagram of how the batteries were wired up I knew exactly where the trouble was. Only because I used to work in the RV industry and worked on many coaches with multiple battery set up and often saw issues like this. Your scope use just blows me away.

[@spelunkerd]

At first I was a little surprised you are using current from the battery charger to get electrons moving enough to do the testing, but then I realized it is such a common situation, the technique almost falls into your lap. Good idea. I have to confess, with the big difference in voltages between the two batteries, I would have switched to static testing with an ohmeter, then switched back if I didn't find the break. It would be interesting to see what kind of current flows on those 12 gauge wires 'protected' by the 150A fuse. Even in an old truck, as you point out, that's a fire waiting to happen when either battery eventually fails. If he didn't want to pay for a heavy connection wire, I might have added a fuse to the 12 gauge wire to protect the 40A limit it is designed to carry.

[@leereynolds2911]

i would have put jumper cables on both batteries to produce a common ground then check battery voltage then it would show no voltage drop then it would show a bad ground

[@putsowetmefdupa1]

I noticed CCA has made it's way into battery feed cables for manufacturers to save money. I learned my lesson by avoiding CCA which stands for Copper Clad Aluminium. It looks just like copper at a lower price. The aluminum deteriates very fast but the wires still look good. Made the costly mistake of using that garbage on a front and back winch feed and had to replace all of it with copper welding wire. Don't be fooled by the cheap CCP crud. Look for solid core copper. battery feeds. Looks like this truck was a victim of that garbage. The way you can verify it, is hand torch it. The aluminium disentigrates fast where-as the copper just heats up.

Whenever I installed an Aux Battery that was connected to the Main Battery directly, or through a Battery Isolator/Battery Charging Relay, I ALWAYS ran a ground from the Aux Battery to the Frame AND the Engine! I've eliminated SO MANY problems that way. I had a Ford F250 that spent most of its like at a different (Los Angeles Dept of Water and Power) yard, NEAR TO the Pacific Ocean. Needless to say, there was plenty of crusties in the sheet metal, parts of the frame and........you know the song. The vehicle had "INTERMITTENT" electrical problems for over a year. The mechanic at the yard finally gave up on it, brought it to me. (I was the Auto Electrician at the Main St, L.A. Shop) I did LOTS of voltage drop testing, both with engine running AND using the SNAP-ON Battery-Alternator-Starter tester while loading the (Power, Ground and other) circuits with the tester. Without a load, some had up to .5 Volt voltage drop. Loading it produced a surprise from the same .5 Volt drop, up to 1.5 Volt Drop ! ! So, I ran a 10 gauge black wire from inside the cab at the ground in back of the Driver Side kick panel (2004 F250 with a 5.4 V8), through the bulkhead/firewall to the grounds on the bulkhead, the driver's side inner fender panel, the radiator core support, to the passenger side inner panel grounds to FINALLY, the Small Wire battery ground on the passenger side inner fender panel. The original ground at that point was loose, thanks to a (AGHHH) sheet metal screw ! ! I installed a "nutsert" into the panel and connected the new 10 gauge ground with the battery ground at this point being held by a 1/4" bolt and lockwasher tightening everything to Mike's Torque Spec! Retested for voltage drops, most were at .1 volt UNDER LOAD. The 1.5 Volt under load voltage drop went to .3 Volts drop under load. The driver took the truck, the next time I saw it was when I did the smog test to it about 6 months later. ALL my connections with the 10 gauge were crimped and soldered. No more problems.

Excellent video Eric, the bottom line here is the ability to fault find using voltage drop with purely a multimeter and not complicating it with "other" tools. Most folk play with the positive but tend to "ignore" the negative as I suppose it's deemed more complex, but it's not. It's a process many people do not fully understand, but, it's worth going through the pain to understand. Certainly speeds up fault finding once you do fully understand.

To make sure that insulation for cables is working correctly in high voltage usage. The first time i was introduced to this test it left me in awe. Cause I had never considered that a failure point. Just like with any test/measurement equipment. Its important to know where your equipment is inaccurate and how large the inaccuracy can be in those ranges.

I like the way you trouble shot that problem. Thorough and straight forward. 👍👍👍

[@beechwood619]

If the batteries are hooked together in parallel, how can you get different voltages on your meter? Shouldn't your meter show an equal average of the batteries on both batteries? Looks like a bad ground somewhere to me.

Yes and yes

I guess I like his demeanor he goes down to business finds it. He works hard at what he does. He should be paid very well. I don't think he's getting paid enough. May God bless him and his family and they do very well in life.

That's wrong... You didn't use any Brake Clean for this whole video!!! :) BTW, I saw the my local Autozone started carrying Fluid Film. Bought a can. It has definitely earned a spot on the top of my tool box beside my Kroil.

+South Main Auto Repair that's just to keep the government from snooping on all that top secret info on brake clean and beef jerky you guys have been talking about.

Could have taken the battery charger and hooked up positive to the battery and connect the ground to the alternator. The check the voltage at the battery. Then move the negative charger cable to the frame and check again. Keep up the good work. Really appreciate all you do!
