Case 4690 3PL Hydraulic lift.
My arms are controlled by a 3 position switch UP ,MID, DOWN and that switch in the cab is fed by a wire wound resistor.
The hydraulic pump seems to be down near the arms.
Mine used to work but now it doesn't as inside the cab got wet.
Putting 6 Volts direct on the pump contacts does not start it running and even touching 12 Volts does not get a response.
Can anyone tell me how these work and what I should be looking for to get it going? I'm assuming I will have to pull the pump down . Checked power in and all that ,fuses etc.
I cant find a manual or drawing or even a circuit diagram on the 4690 so I'm flying blind.
