i have had so many electrical problems (flying through optima batteries) ever since I got that damn pulley installed. If i wasn't so lazy I would take it out....
I'm on my 3rd Optima yellow top Battery in a yr and a half. The same day I put my last one in it was already at 12 Volts when I was shifting, idling.143hawaii said:It could be your battery. If you garage your car a lot, drive a lot in stop and go traffic, etc. your probably not seeing enough load to get your battery recharged enough. Combining the underdriven pulley with any kind of audio system (amp/subs/etc) and that would also make things worse.
