We have just purchase a Crown model 20Mt-S serial number 1A15911. looks like it has light use, but not maintained properly.
The drive wheel only runs sporadic, and only in the slow mode when it does run, you can hear the magnetic switches kick in but not the drive.
So far I have cleaned all the post, refilled and recharged the batteries, which were really low, and cleaned the connection to the drive motor.. I have started to clean the contacts on the magnetic switches and checked the safety switches.
Any other advice or problem areas I should be looking at? Also where can I find a wiring diagram and owners manual to download?
Once I get this running I will replace all the batteries, Cables and batteries look new, I don't want to put too much money in before I find out this is just an anchor
thanks in advance

Anyone have any experience troubleshooting the drive-wheel circuit on the 20MTs? The motor by the wheel is getting power from the 4 wires coming in, but when I twist the throttle it doesn't work in either direction, turtle or rabbit. I kind of suspect a fault somewhere in the switch circuit. But would appreciate the benefit of anyone's expertise.
Pulled the motor everything looks good, bench test runs perfect. i'll keep looking,
Thanks!
Thanks, I never thought of brushes.
I would take a look at the brushes in the drive motor. If they are worn and not making good contact you would have those symptoms.
