Unfortunately one of the soldered wires to the underside of the chassis has detached. Can anybody with a working rocket post a photo/diagram of where the wires are soldered.
Service sheet HSS 451 does not show this.
Many thanks
Bob Hughes

If no one else has done it by tomorrow, I'll dig mine out and try and take a few photos for you.

Is it the wires soldered to the front of the tender? Or are they soldered inside the loco somewhere too? Can’t really see how the loco comes apart and as it’s so small I’d rather not try taking it apart.

*edited to add* I can’t even find my small screwdrivers to have a go at taking anything off at the moment either, sorry.

Wires soldered to the underside of the tender.
Just one has come adrift.
You can see the positions when you invert the loco+tender

This is the best I can do, camera seems to want to focus on everything but what I want it to! Hopefully this link works, trying to do it off my phone...

The pcb they are soldered on fits into the adjacent pcb with a miniature flip catch connector so if you release it it will be easier to solder back on as you can do it away from the plastic body. Really a major weakness - they should have arranged for a cable clamp across the wires to stop any pull on the soldered wire joints.
