Well, here goes...

Friday nite, I was working on my toyota/samari.... 87 samari with a 22re engine/tranny/transfer axles.

I have the sami running off of the stock wiring running the headlights/tail/wiper/blinkers/heater horn. The toyota engine is running off of the efi wiring harness from the engine/fuelpump/alternator/sr5 gauge cluster. Here is my problem.... My buddy who will is a little unmechanicly inclined was helping me out on the sami, well everything was going good and we where closing shop up. My battery was dead so I had him hook cables up from a spare battery to mine. Bad mistake... He ended up hooking the pos/neg on the spare, reversed to my battery, needless to say sparks flew for about 5 seconds before he unhooked them. Needless to say I was pretty pissed. I started it up and my check engine is on, also the brake charge is on. (brand new alternator before this) also the wipers go on with the key (sami system). Volts on the sr5 gauge are pegged above 18. What the hell got fried? I tried a diff battery with no change. All fuses are good. I unplugged the alternator and ran it without t!
he alternator plugged in to the main harness (but with the single gauge wire from the alt still connected. No change.. Any idea what got fried?
