Weird short?

If the M1a is new, send it back to Broadway. The engine is advertised as DCC ready, so it should not be giving you this problem. If you mess with it too much, they may say you've voided the warranty... Quit while you are ahead on this one!

Yes, power trucks can be a problem. I have a Lambert Brass railbus that has the wheel wipers/power pickups integrated with the motor brushes, and it's almost impossible to isolate the motor because of the miniscule distance between the wheel and the motor.

The M1A already came with a pair of wires disconnected in the tender that my friend tried to solder together, not really knowing where they go, so i'm going to say that the warranty is already voided. I'll still tell him to try and send it back, i didn't do any surgery on the model.

As for the power truck, the wipers and motor are on two different assemblies, so they are very much seperated. The only way into the motor assembly is through the pair of wires that you can easily disconnect from the wipers, so i have that straightened out as far as i can tell, but i'm still worried about the humming noises.
