Diagnosing a servo fault

 

Before taking Ragleth to Andy's layout, I needed to perform a little fix. You see, last time I'd run it at railway club, there had been a little oil fire underneath it. And after that, the regulator servo stopped working. 

Of course, I'd meant to do something about it, and yet nothing had been done until a few days before the event. 

Still, I managed to remove the loco body, and quickly identified the problem. Those wires are a bit cripsy!

The servo casing was somewhat distorted to. 

The solution, dig out my last spare full-size servo, and swap it out. About half an hours careful work, and all was well. 

It was too. We steamed perfectly for a single trip. And then the servo stopped working again. Time for another look...

Hi Phil, you might want to find out the cause of the oil fire - that was probably what did for the servo wires...Good luck! Regards Richard

Split oil and lighting up the loco. The problem in this case is my carelessness.
