Richard-358946 Posted March 5 Share Posted March 5 Hi guys, i dont want to alarm anybody but it might be worth checking your motor wires are not rubbing on your flywheel in your power cars. I like to pull things apart and found my red and black wires were rubbing on the flywheel weight.. ive caught it before it turned into a problem but it may be worth looking to avoid a future short and possible decoder short happening in your locos. Il try and add a photo of said issue.. il probably tape my wires so they are pulled away from the flywheel or dab a bit of superglue to hold the wires away from the flywheel... Thought it best to say something now and hopefully it can save future headaches for people. There are four screws at the front and rear of the big PCB. Once removed the pcb just lifts up to reveil the motor as shown below... 3 2 Link to comment Share on other sites More sharing options...
Rallymatt Posted March 5 Share Posted March 5 Great spot, this is something that could be fed back to Hornby too, could a Mod do that please? 1 Link to comment Share on other sites More sharing options...

gilbo2 Posted March 5 Share Posted March 5 Blimey, that is all rather tight! In extreme examples I'd imagine performance would be impacted too. Link to comment Share on other sites More sharing options...
ntpntpntp Posted March 5 Share Posted March 5 (edited) Won't be the first time I've seen that sort of problem. I notice it's more common with Far East chassis designs where there's a lot of hard-wiring in the assembly, for example Hornby/Arnold N gauge locos that have been re-worked for production in China have far more separate wiring than the old German-made chassis which tended to use sprung contacts routed along the block. Are the motor wires captive to the can or soldered to the brush tags? Edited March 5 by ntpntpntp Link to comment Share on other sites More sharing options...
BigTop Posted March 5 Share Posted March 5 Would a piece of insulating tape on top of the motor be ok to hold the wires down and away from the flywheel? Also worth noting there’s a cheeky transparent washer for each screw between the pcb and chassis. 1 Link to comment Share on other sites More sharing options...
Rallymatt Posted March 5 Share Posted March 5 I don’t see why not, and I think Richard mentioned the transparent washers somewhere else but not this thread. Good spot Big Top 👍 Link to comment Share on other sites More sharing options...
gilbo2 Posted March 5 Share Posted March 5 I wonder when the loco is assembled in the factory whether those wires are pushed back over the motor with a thin tool and then the PCB 'clamps' them over it? Just a thought. Link to comment Share on other sites More sharing options...
Baz657 Posted March 5 Share Posted March 5 I'll check mine tomorrow when it arrives (should have been today but hey-ho). Thanks for the info. It's what these forums are all about. 1 1 Link to comment Share on other sites More sharing options...
