I've been taking apart stuff on my buddy's Komatsu PC150LC-6 over the past year, and there's one thing I can't track down anywhere—a connector diagram for the throttle potentiometer. Just swapped it out because the old one was shot, but somebody had already cut the original connector off. If anyone's got a picture of theirs, I'd really appreciate it. This forum's helped me fix a lot on this machine already.
