I did some searching, but I didn't come up with much and electrical issues are my biggest weakness. So if I'm asking dumb questions, please enlighten me with your ingenuity.
The car: 1984 Brat with a replaced EA81. When the engine was replaced, some "extras" were removed and I definitely have some wires to nowhere.
The issue: Recently, when I turn the key to start the car, 1 of 2 things happen. It either:
1. Starts right up.
2. The dash lights up, the battery gauge needle hits about 8-10V and the starter doesn't turn.
If it starts and I drive it there are no issues. If I roll start it, jump it with the 50 amp setting on my batter charger, or jump it from another vehicle there are no issues running it and driving it. Once it is running the needle sits just above 12V and everything is great.
I got my battery tested. It is supposedly fine.
It seems that no matter what, if I drive the car then shut it off, it always starts back up if I try within a few minutes.
The questions: Is my starting circuit grounding somewhere intermittently and killing my battery? I'm assuming an intermittent short to ground because sometimes the battery is fine and other times it gets drained very quickly.
What should I look for?
Edit: I'm not sure if it matters, but the car had been mostly sitting for a year while I worked on it off and on to finish the lift and do some rust repairs to pass inspection. I just started driving it again last week and that is when the issue started.
Edited again for grammar.
