I recently acquired a used 25011 set. The trolley would not move so I took it apart and found that by loosening the mounting screws on motor assembly it would run but has little power (will not move when body put back on). Voltage to track is 7.4 v. Have cleaned all contacts, track, etc. New motor needed? Also, instructions says one section of track is an activator track for reversing. Set has 3 straight tracks but all look the same-like regular track. Are activator sections available separately? Thanks
When you say it has little power do you mean it runs slowly?
Is 7.4V the maximum voltage you have available?
These items are rated up to 12v DC so I would try it on a higher voltage before thinking of changing the motor!!
Hope this helps.
Thanks for reply, Steve- The voltage on this set is fixed at 7.5 volts- no varible speed. Motor runs with no load, but as soon as load added (streetcar body) it won't move.
Can you remove the motor from the chassis and see if the chassis moves fairly freely?
Could be that the chassis needs freeing up a bit.
The 7.5V would normally make the car run at a reasonable medium speed the higher voltage I suggested earleir would make it go like the 'clappers ' (Thats an english term for rsther fast!!!)
Mine >:( is doing the same thing. I sent back the trolley thinking it was that. But the trolley returned to me does the same thing. If I put the trolley on a track controlled by a higher tranformer the trolley works fine. I haver cleaned the track and at all connections it just doesn't seem to be getting any power??
