this truck only has 140 k on it. I'll hook up the pics tomorrow. As for the sound, I'll have to listen to mine when it does it again. The terminals were pretty gross, cleaned the crap outta them and the battery connectors. The truck cranked kinda slow and I thought it was just because of an old starter, always started right up the fist time after wts goes out. Now, vroom, the starter doesn't even really have to engage. I performed a load test on the alt, because I noticed that the voltage gauge looked a bit on the low side. but charges good at 14v, and recovers well when load is applied, dropping just shy of 12vdc. the volt meter in the dash is lying. but before fixing anything, I really need to get the tank switch issue figured out. trying a google search wasn't a help, maybe I am searching the term wrong. I'll take a look at the ebpv too.
