My loader wont go into forward or reverse. The parking brake light wont go off. It has had this problem but after moving the parking break switch back and forth it finally goes. Not any more. I took the switch out and it has a yellow, white and black wire. The yellow has 24 volts as long as the key is on. The black wire has 24 volts when the switch is flipped it's way. If the switch is flipped so that the black wire has 24 volts. The white wire will show zero volts. But for some reason after a few seconds the white wire will show 24 volts. I cut the white wire and it still shows 24 volts until I turn the key off. I suspect it's some kind of relay. I would think when you flip the switch off of park that it should have no voltage flowing back to the parking brake switch. I checked the switch with a meter and there is no feed back in the switch, it is fine. The Komatsu dealer is 180 miles away. Thanks for any help
