I am an active duty member with 30 years of service in the Army. Married with two daughters, and a grandson. I love tinkering around with auto mechanics and helping my neighbors save money in automotive repairs. I found a truck that I used to own 11 years ago, and had sold when stationed in Alaska. I found it in Texas and bought it back. I am in the process of restoring it. I replaced engine and transmission, new suspension, brakes.... too many things to list.
My current issue is with the battery light being on and the battery draining. The alternator and battery are completely new. I have checked the wiring and everything seems normal, no tears or torn cables.... I am puzzled as to what can be causing this issue.

First, check your alternator output. Even if it is new. The next thing I would check, would be possible draw on the battery. Check amperage draw, not voltage draw. If you have a 2 ,or 3 or more amp draw, you have enough draw to run your battery down. If you have a draw start to eliminate the source. Dome lights, glove box light, under hood light. If all of these check good, start (one at a time) pulling fuses while watching ammeter. If you find a circuit that stops the draw, look in your owners manual and see what all that fuse feeds. Then narrow it down. When the battery is low the battery light will come on. Hope this helps.

What year and model is your truck?

30 years that's a long time and still active. Damn.

I had a 2 yr army run with a little over a year in Vietnam. I was happy to make it home and got out.
