Same as what?

Thanks for the info, I remember viewing "OOBill" on YouTube checking electrical continuity with some sort of meter (not sure if my voltmeter has all the functions his has) but it all baffles me. The blanking plate is my best guess but I can't check just yet as I've asked a model shop to investigate.

Thanks. The 4-pin plug was silll firmly in place. I've since passed it to my local model shop to have a look so they'll probably spot the blanking plate as I didn't check that, I was more minded to think the motor had suffered shock damage from being dropped in the post.

Thanks Al, the little plug was still securely fastened and wires apparently intact.

I never thought about the blanking plate, I'm not DCC-savvy so have never delved into that. Will it have done any damage when I tried to run it with the plate was dislodged? I don't have the loco at the mo, a model shop is taking a look.

Could anyone please advise why my Black 5 (R3323) might be refusing to move. I've tried putting transformer leads to various terminals and wheels and get no reaction at all, it's completely dead. Background is that it was damaged en route to an eBay buyer, box end was crushed a bit but the inner plastic packaging and the loco itself seem untouched, pristine to look at in fact. What might a shock from being dropped do to the motor perhaps?

Thanks.

Hornby have just returned my R2383 City of Nottingham loco as unrepairable due to its age and non-availability of parts (bought new just over 7 years ago. The motor is slipping, lots of whirring, no traction. I keep reading and seeing videos of this common fault (in itself a bit damning) so I'm hopeful that someone in the Forum can help me with a fix, not least as I have two other 'Duchess' locos with the same problem, so £300-£400 of useless locos. I took the loco apart today and couldn't detect any slippage on the black plastic axle cogs. I then took off the worm gear cover and that seemed fixed solid too. So my questions: 1 given how fiddly the wheel set, valve gear and pick-up contacts are from the underside, is it likely to be these that are slipping or more likely it's the worm gear which is a little easier to get to? 2 do forum members approve of the oft-quoted solution to use superglue to fix the cog or worm gear? 3 can anyone please recommend an approved Hornby service agent in Berkshire in case it's all beyond me.
