Oops. I made a bad mistake - one I know better than to do. I assumed black would be negative and red would be positive. Someone before me wired a connection to the house battery w/ a black positive. I was messing around w/ my battery and inverter and managed to reconnect it to the neg. side of the battery. I know, I know... House lights didn't work so I started testing and found the problem. Fixed and all is well - at least on the house side. After I got it all working properly, I decided to test voltage at the inverter w/ the engine running. I started the engine but the charge light didn't go out. I have 12.2v across the starting battery posts w/ the engine running. I checked all the fuses and the fusible links in the black fuse box to the left of the engine (facing the engine) and everything checks out fine. I am wondering what a dead short on the house side of the isolator could have burned out on the engine side of the isolator that would keep the alternater from charging, It's an 87 w/ 22RE and AOD trans. Got any thoughts or suggestions? Other than "don't do stupid stuff like that again", I mean...
