Yeah, I know it sound weird, but it happens every time consistently, the rps drop to 0, and then the voltage starts to drop. sometimes for 10 seconds, sometimes up to 20 mins. doesn't matter if it is sitting idle or doing 60 down the road. I spent some time yesterday looking for a loose connection, didn't find any. Is it possible the crank sensor is going bad, I'm assuming that is where the rpm's are being measured. Here is the pic of the sensor http://www.oreillyauto.com/site/c/de...d=crank+sensor Although I still don't see how it would affect the voltage the way it does, any info would be helpful.
