6-12867 Powermaster Problem

If pushing the red “Oh ****” button isn’t killing voltage then I’d say there’s something wrong with the power master.

@PRRick posted:

The other will not completely power down regardless of what I do. When I roll the CAB1 red wheel the whole way down the volts reduce from 19 to 10. The halt button also just decreases the voltage back to 10v, doesn't kill it.

Just to be sure, reset the stall voltage to 0 and set the momentum to low.

Thanks for the replies, didn't work. I also just put a PW 681 on there and it constantly whistles. Although the PM1 red light blinks as though its receiving the command (change direction for example), nothing happens. Not looking good.

PRRick - Have you tried the other way to shut down all power by pressing the following sequence on your CAB-1...

Press TR - then press # you've assigned to that particular track - Aux 1 button - then 0?

I'll try that, PH1975! Thanks (EDIT: DIDN'T DO ANYTHING)

Based on a little research, it seems like a bad mosfet. I found a really nice video (https://youtu.be/qRmuNFU459A) skip to 11:00minute mark and he begins to explain my problem where I can't get the volts down.
