All,
Have a Bachmann Christmas tram, which refuses to run.
Initially, I thought it was missing one of the square silver contacts adjacent to the motor. - These pass current from the pickups to the motor et al. However, I replaced the missing piece with a couple of bits of folded wire.. Lights are rock solid, but motor refuses to run well (if at all).
Even if lift the motor clear of the gears, and put power directly to it in stalls. - I think the brushes are shot, as it arcs internally.
I have two choices:
1. Try to source a new motor. - Led to believe these motor blocks can be problematic anyway, so this might be false economy.
2. Replace the block with something else. - I have a USA Trains block (sort of) bought for this purpose. Would need to cut the axle-ends which protrude beyond the wheels. Wheels are a lot smaller diameter, but look better IMHO. Drill motor block for 'skirt', does give me the option to increase the track clearance a bit.
Second option a bit scary.. Having-at a new motor-block. Probably trimming the wiring mounts off the tram, and fabricating some sort of mount for the alternate motor-block.
Anyone any brilliant thoughts, or alternatives please?
