If current not passing through ABS unit, to leads at bottom the wire (brake control wire to motor, in soft rubber boot) connected to. Than likely the ABS unit has failed. I've seen it happen twice!Thank you 2001LC!
The system was completely depressurized as I removed the MC to replace the pump motor with a new motor. After reinstalling the MC I bled the fan brakes with the ignition off. When I turned the ignition on the new pump did not come on. I tried to bleed the rears without pressure from the pump, which seems impossible, to brake fluid come out of the bleeders.
I bench tested the motor I removed and it started without issues. The terminal on the motor looked like new. The terminals on the ABS unit side are corroded. I used a volt meter to test both terminals. With the ignition on I get 12 volt on either, turning on and off as a relay clicks. I did not jump the leads as you describe.
Should I still do that test if I observed current at the terminals? Would this indicate the the new (not rebuilt) motor is bad?
Thanks!
