Step one was testing power to the pump switch. That passed
Step two , I took the pump out of the car. Would not turn when you power to
the wires. I tore it down to see if the gear was caught, even after removal
of the gear, the motor does not turn. There is something inside the motor
which is causing a short. I took the motor all the way down but there is no
evidence of a problem.
Brushes look good
windings look good
Some kind of blue lubricant(?) on the commutator. Looks original
I can't see any reason it does not run, but it blows a fuse that is 3 times
the call for size and does not turn. I may return it to Mallory.
