OK, I'm going to need a little help here today, fellas. I'll do my best to make a long story short:
'95 Miata M with OEM AGM battery. Car was sitting for a while and had enough juice to run the door buzzer and the dome light, but not to start the car. Buddy of mine decides to just jump start it and hooks up the cables to another car, but he got the cables wrong on the Miata end (the negative terminal is painted bright red for some reason on my Miata). There were no theatrics, no blown up cars or batteries, and the other car is perfectly fine. However, the Miata does nothing now; even the dome light won't light up when cables are connected correctly.
I put a 2 amp trickle charger on it last evening and it seemed to show that it was charging, but when I went to check on it this morning, it showed that it wasn't charging at all. I figure at the very least, I screwed up my battery and need a new one, and at the very most, I royally fvcked up my car and I need a new electrical system.
Can someone tell me what I need to check or do? Thanks in advance.
