1998 Cadillac Concours V8 Front Wheel Drive Automatic 132000 miles
I had/have a weird electrical situation going on. Without any warning, I attempt to start the engine, and I get erratic dash lights the starter doesn't turn the security system starts the horns blowing.
I turn the key off, it stops. Thinking maybe a it's a "ground" issue, I attempt to clean the bat. Terminals. When I removing the ground term. The horns start to blow, as though the security has be activated. So, I remove th hot side first, then the ground and no problem. After cleaning the terms, I try to start the engine and "no" problem. Thinking "all is well", I go to use the cars and this issue starts again. I go through the process again, but this time I clean the engine side of the bat. Grd. Attempt to crank, she starts no problem. Through this clean process, I found no "real" corrosion anywhere. I'm thinking some relay somewhere is causing the no crank, dash lights buzzing, horn blowing going on. When it did crank and fire and run like normal, I notice the radion was dead. No, apparent electrical connection when turning it on. Also, after turning the engine off, I hear this electrical kind of rumbling noise in the speaker system and all of the indicator lights on the transmission gear selector strip light up. After a few seconds I all shuts off. I have benn able to crank and fire. There is not indication of impending battery failure.
Any suggestions or clarification needed?
Thanks for any leads.
