I recently purchased a used MTH Bump N Go trolley on ebay. When I place it on the track and power up, the lights come on but the unit does not move. I have attempted pushing the bumpers as described in the owner's manual, but have had no luck. I am using a compatible transformer according to the owner's manual.

Any ideas on how to fix this? Not certain if it has been reprogrammed. Is there a way to return it to the factory settings?

Any help would be greatly appreciated.

A bump and go trolley has NOTHING TO REPROGRAM, there is no "reset", and there are no factory settings.

It is 100% a mechanical switch and rectifier. The bumpers activate the mechanical 2 way switch through long plastic parts to reach the switch. The lights are on a separate circuit from the motor so they only indicate you have power.

Possible failures (since the lights indicate you have power):

Switch just in the middle of 2 directions and pressing one bumper or the other to fully move the switch to one direction or the other

Bumper parts broken that no longer activate the switch (caused by hard impact to bumpers- dropping it, slamming them going too fast)

Locked up motor or driveline

Damaged switch (same things that break the bumpers can break the switch with hard hits)

Burned up rectifier (caused by locked up or failed motor- replace BOTH)

This uses the SAME parts as the bump and go handcar- just minus the handle gears.

Basically these few parts

18 - switch and rectifier board

5- motor

23 and 24 - plastic bumpers

Again, there is very few parts involved in moving.

Motor can be bad, or the board/switch.  Parts should be available once you determine actual issue.  G

Thanks for the replies. I have replaced the switch and rectifier boards but no luck. I will try a new motor.
