PowerMasters Problem

Could it be your CAB-1 since both PM are not responding.  G

Yes, checking for voltage with a meter or even a light bulb at A/U would be appropriate.  Are you trying to run Command or Conventional?

Are you trying to run Command or Conventional?

What Dale said.  There's PROG/RUN and CMD/CONV switches on the side, make sure they're in the correct position.

I'm running conventional.  The PROG/RUN and CMD/CONV switches are in their appropriate positions; like I said, everything was fine, nothing changed, and now I have problems. 

I'll take another look at the Cab-1, try replacing the batteries, but I can run my line with Command just fine (I have 3 lines: 1 command, and 2 conventional, the two conventional lines have their own PMs which are malfunctioning).

Are PMs known to spontaneously break?  I've had these for several years now and never have had any problems or issues before.

Could you have some sort of overload condition that took them out?

I have PMs from the mid late 90s and they still work fine.  Can you reprogram their track number and try again.
