Hornby Railroad Class 37

[lee74clarke]

Hoping someone can help me with a poor running Class 37 chassis.

 

I picked it up relatively cheaply from that well known auction site (wouldn't you think I would learn my lesson buy now) so am not overly concerned, but would be nice to get it running. 

 

I run only DC, so no issues with removing some wiring, if that indeed will help. Now, allowing for the electrical luddite that I am, can anyone tell me if bypassing the circuit board will give me a decent runner, and if so, which wires am I altering?

 

Thanks in advance.

You shouldn't need to hack anything about.

 

Just get hold of an 8-pin blanking plug (they are easily obtainable as spares or a mate who uses DCC should have some he's removed).

 

It's a straight swap for the harness and chip.  

 

Hornby part number is X.9255

That's great, thank you John. So, on the last image, it basically splits between the small green plate and the larger darker plate, then the blank fits in there? Apologies for my ignorance!

Cracked it! Tried with a blanking plug from another model, runs like a dream now.

Just need another blanking plug now, can’t see the right one on e-bay.

Thanks again.

You can easily make a blanking plate.

 

If the model does not have lights then just bridge the two pins at each short end of the socket each with a bit of wire. This connects a rail to a motor brush at each end.

 

If the model has lights then include the next pin along in an L shape to match this pattern.
