Over the course of time, I have pretty much striped completely the motor and solenoid pack trying to find the issue and think I know how the motor, solenoid and wiring works, but have one final problem to solve
below is 2 pics of the brush holder
now, power comes in to the brush holder via a connection to the copper bar *the small screw hole in the top pic) running across the top of the holder to the opposing brushes.
my guess is then it runs through the armature and to the other 2 opposing brushes and here my problem starts, these brushes don't seem to earth well to the brush holder chassis which would inturn pass the current to the earth attached to the motor chassis.
I believe the fault lies in this earth issue, any advice???
