Local LHS asked me to look at this as it does not run. Can i test this with my MTH Z controller ac track? It is a weaver NN1301.

Like most modern trains the motor itself runs on DC whether it is 3 rail or 2 rail. So:
Yes, you can use your AC transformer to test it if it is a 3 rail model as these had an electronic reversing unit. No, if it is a 2 rail model. I believe the 2 rail models only ran on DC.
BTW, I have extras of those electronic reversing boards for the 3 rail versions if you need one.
and yes it is 3rail.
The Pittman motor is DC only. There is a circuit board in the 3-rail units to convert the AC to DC.

Thanks...i will be troubleshooting next week.
I've just installed a Loksound Select into my Weaver GP-38. The only way to get the loud buzzing to stop was to switch off the BEMF.
Are the Pittmans all like this, or did I get a dud one?
Cheers
Weaver horizontal-drive 3-RAILengines were designed to take AC track voltage, but would run on DC as well since there was no sound. Their behavior would be neutral, then forward, then neutral, then reverse with each application of power.
The 2-rail engines are DC only as there's no reversing unit. ll
Thanks Matt. I didn't know that the 3 rail versions will run on DC. Learn something new everyday I always say.
