Hi
I've nearly finished the restoration of my TR3.
I cannot get the wiper motor (Lucas DR2) running though.
Before I remove it from the car to clean it and repair it, it was working fine :-(.
When testing it on a bench and put power on the spade connectors the rotor gets 'stuck' on the stator and doesn't move turn. I can also hear a buzzing noise (like electric power lines).
I've tested the commutator with a ohmmeter using the 3 recommended resistance tests (180° , bar to bar, shaft); and obtain similar values.
And when I put power to the commutator, it creates a magnetic field.
So it seems the rotor is in good order.
The stator also creates a magnetic field when connected.
Any idea on what could be wrong with the motor ?
