so i have a 2000 gc, same symptoms as all, gauges die christmas tree lights up. checked bus signal at diagnostic port and reads 6-7v i disconnected alternator and everything works just perfect!! V at bus drops to a normal 1-2v, replaced alt and same thing. could it be the regulator shorted inside pcm thats causing pcm to go haywire?
