I have a 2005 kama 354 gauge panel stopped working noticed a fuse missing could not find any of those funky wire fusesĀ and switched to an automotive fuse panel. didnt solve the issue.tractor starts and runs fine just none of the gauges work including the tach.i found a small connector box behind the dash that had a sm.pc board inside with a broken transistor replaced that. wasnt getting any power through the regulator so replaced that and as soon as i started the tractor the regulator smoked.does anyone have any ideas? also can anyone help out with a wiring diagram so i can trace all the circuits?
