Williams engine won't keep running.

If I had to take a stab at it it sounds like a reverse board to me. I have a couple extra with no wires. I'll sell one for short money if your interested. E-mail in my profile.

I tend to agree with Chris:

*  if it was mechanical (motors or gears) the engine would either not work, or run very slowly or intermittently all of the time, not work fine for 30 minutes and then quit.

*  so it sounds like electronics are heating up, and do a partial fail when the temp gets to a point.  When cool, it runs fine again until.

*  the only electronics in the Williams is the reverse unit.  So that is most likely the problem.

To see if it's heat related (like Ken mentioned) take the body (shell) off and run it. If it's an overheat problem it should either continue to run or at least run longer until the failure ocurrs.

You might also examine the board mounting.  It could be as simple as a loose or missing heatsink that is allowing the board to overheat after some running.

 

It could also be a loose connection or a pinched wire.

 

Also check the lubricant on the worm gear inside each truck. If one or both are gummed up, that could cause overheating. Someone encountered that in a recent thread. Replacing the lubricant solved the problem.

Maybe the engineer figure needed a break after all that run time. What are in his union rules book?

can you hear the motor running when you try to move it.

Have a set of Williams F3s, and they did that.

pulled the powered truck off one of the motors and the

drive gear was striped. Had to replace the entire truck as

Williams does not carry parts.

 

Left one powered truck in the original powered F3 unit,

took the new powered truck and mounted it in the F3 dummy

unit w/ rectifier. now I have two powered units that will run together

and I can run them separate for two trains.
