Hi from N. Lincs. I have a problem with my motor mover, the indicator shows it to be an earth to chassis. I have disconnected the leads and the control box shows no problem. Reconnecting the right hand cables that motor works a treat on connecting the left hand cables the fault comes back. The cables are not damaged so it looks like the motor is at fault? Could faulty brushes cause this or is the motor itself crocked ? If so, is it difficult to replace the motor? Any help will be most welcome. Cheers Kenz.
