New guy with a electrical question
I recently bought a 96 250 crew cab long box with dual fuel tanks with 230,000 on it. This is my first diesel btw and I love it so far. The problem I am having is with my charging system. My battery light keeps flickering. The guy I bought it from replaced the alternator not to long before I bought it. Now some times the light will flicker on a smooth road or a bumpy road. It will also flicker when I'm jus sitting there idling. (Which means the problem is close to the engine I'm assuming) if it starts going crazy if I get on the gas and accelerate hard the light goes off.
The truck did quite on me one day after the light was flickering for a whole and I went and bought a voltage gauge because the stock on doesn't work. I am trying to figure out where to start diagnosing this. Ive had the truck running with my wife in it and I've wiggled everywhere and harness I could find and the light didn't illuminate at all. Am I looking in the wrong place? I also had autozone test the alternator on the truck and they said they couldn't guarantee the accuracy because of the dual batteries.
I'm guessing I'm looking for a short or a bad ground somewhere. I'm just not sure if its under the hood.
Thanks for the help.
