This is embarrasing,,, but I can't find it. Looked all around engine compartment, around cab and seat. Just don't see the darned thing. I want to check fuse for traction lock. So far I have swaped relays no go. Parking brake plug was allready disconnected. I assume you dont have to jumper plug. I removed traction lock to be able to move machine. Solenoid metered .3 and 10.2 so that should be ok. Was thinking of a way to bench test solenoid. Any ideas there? Also thought I should check alternator output. I don't think it was the fuse because it was a sporadic problem, but now traction lock won't unlock at all. I got some good ideas from you guys here and downloaded parts of the manual from Old Machinist I appreciate the help.
