I recieved a forklift that someone else was working on. They said that it was blowing fuses and that the mast was locking out after it was washed. I originally thought I was chasing a short to ground since it was blowing fuses. I was looking for where a wire was rubbed through and grounding to the frame but found none. I checked all the fuses with a meter and they were good, but the mast spool was still locked out. All the relays were clicking and working. I took a step back and started over since I couldn't replicate the alleged electrical problem.
There are two solenoids on the machine:
One for lift and the other one for tilt. I tore off all the panels to get to the solenoids. I switched the pigtails for them to see if the problem followed to the tilt cylinder. That way I would know if it was electrical or hydraulic. The problem didn't folllow it so I knew it was the solenoid. To verify I put power to the solenoid and it didn't click like it should. Bad lift solenoid.
