Komatsu PC270-LC6 Key Switch Wiring? No power?

NNYDairy · 2021-07-14 22:49

Hello just looking to see if anyone can inform me on what I should have for wiring on my key switch? More specifically which one is the hot terminal? For some reason I have no key power and it killed everything in the cab. Just can’t figure out which terminal should be full time hot. Thanks

    I'll have to check a wiring diagram for a different model and hope they are the same. I don't have time right now. Maybe you can check the color and maybe number on the small wires on the master disconnect. It should be one of those wires the goes to the key switch for the hot one.
