Hey everyone,
I've got a M1078a0 which has a failed charging system. The truck runs and drives just fine, but the alternator is not putting out any extra voltage (it reads around 24v and 12v when running). I've gone through the whole TM troubleshooting guide and have gotten to the step of replacing either the entire alternator or the voltage regulator.
Some contextual information; when I first got the truck it did have a few weird symptoms that I though were just part of it being a military truck. First thing I noticed was the backup camera I installed would have something like scan-lines going across the screen when the truck was running, but be fine when just running off the batteries. The other symptom was the dash lights would flicker at idle or idling at a stop, but be fine once the truck was moving. Also, the turn signal flashing unit would never flash at regular intervals when running but is fine now that there's only battery power. The reason I didn't worry about it too much was because the alternator was charging everything just fine at the time. But now all of a sudden the alternator just stopped charging.
Currently the truck has a 76761-N1506-1 alternator with a 76761-N3030 voltage regulator.
As of now I'm going to be removing the starter to take to a shop for repairs since it's been acting up (starter gear is spinning before it's all the way out causing it to occasionally grind), and I've been thinking of taking the alternator with it to see if they can run through it and repair any potential issues.
My question to all of you is, has anyone experienced something like this and know what part is more likely to be the issue? I certainly don't want to be throwing the parts cannon at this thing when I don't have to, and it'd honestly be kinda nice if the whole issue was the voltage regulator as that's a relatively quick and easy fix.
Any insight would be greatly appreciated!
