Hi,
Have got a modern Hornby HST out of the loft that I planned to sell (doesnt fit with what I run), but on testing it am having problems. It's a DCC model although only ever run on DC as my layout plans have never developed as hoped (indeed this is a little downsizing).
It runs great forward, but on switching to reverse you get a couple of small judders (with red lights on) and then it dies (lights out).
- Removed the fan to prevent that causing extra load on the motor (this is the older single fan type - I remember it being intermittent in working although I understand that is common)
- Lubricated the axles and the motor to bogie ball joints.
- No sign of any broken wiring connections.
- Swapped decoder with that of the dummy power car.
No change.
There was a some white gunk (grease of some kind) around one end of the motor which had sprayed on the inside of the loco. Is this a sign of the sealed motor having failed and this has come out?
I get the impression it is trying to move but failing and then perhaps the overload is cutting it out? but why would it work fine in one direction not the other, as I can see it, the motor drives both bogies
Any suggestions - I'm leaning towards the motor but its not had a lot of use so that seems odd.
cheers for any help
