An update. I had Autozone test the battery and they said it is healthy. 94% charge and 12.4v.
The ammeter isn’t an issue as it was already deleted. The battery and alternator wire are bolted together.
Now this will sound odd but take it with a grain of salt from someone who doesn’t know auto electronics. It seems like the polarity in the car is wrong, or the car is ungrounded. I tried testing the power wire coming from the battery to the where it was bolted to the wire from alternator and nothing. I took a power probe to one of the switches and gave it ground and power came to the car; the courtesy light came on and the electronic fuel pump came on. Thoughts?
