Last night I was working on the car and got everything back together to get her moving again. It was late and for some reason the colors on my battery are backwards, red and black are switched. So not paying attention I hooked the positive to the negative and negative to the positve. I was wondering why there were sparks, lol. Anyway I did this on my sport bike before and it popped out a breaker switch or relay I forgot what its called. But instead of blowing fuses it deactivates the electrical system to prevent harm. Is there something like that on the e30?? If not how do I start my car? BTW car wont get any power now at all. So chances are someting is probably fried. Im going to check the fuses.
