Legacy Powermaster problem

If you are SURE you are addressing it properly and it's been reprogrammed again, it's likely broken.  Sure sounds like the output pass triac or FET is shorted, I don't think you're going to fix it if that's the case, you'll need a tech to repair it.

The modular club I am part of uses a pair of Legacy Powermasters.  One of them is not working properly.  When you turn power on, power to the track immediately goes to around 18 volts, regardless of the position of the command/conventional switch. In addition, after trying to turn it off with AUX 1, 0 the power stays on.  Even if I use the emergency stop button (red triangle) the power stays on.  Has anyone else has a problem like this, and were you able to resolve it?

Thanks for your assistance.

 

is this the new powermaster 360?

No, not a Powermaster 360. Yes, pretty sure I’m addressing it correctly, reprogrammed the address several times.

GunrunnerJohn, what would the cost of repair be on something like that?

Thanks!

so how about a 6-dash number so we know for sure what you have

It is 6-37146.

If it's just shorted output drivers, it shouldn't be too significant.  I'd contact Lionel and see what they say.

Thanks GunrunnerJohn. I sent an inquiry to Lionel yesterday, so hopefully I’ll get some response.

Sorry to use this old thread, but it is right on point for my problem.  Neither of my two 180W Legacy Powermasters will shut off track power using either the Reset Icon or the Aux1,0 sequence.   One PM does nothing;  the other reduces power to around 7.5 volts.  I have tried to reprogram the powermasters using various TR and ENG #s, but the problem persists.  I  have also tried a substitute  Legacy base without results, so I believe he problem is in the powermasters.  Lionel Customer Service told me that they do not repair these items.

First question:  does shutting down the powermasters (eg. Aux,1,0) reduce power to zero, or does it reduce it to a lower level from 18 volts?

Second:  if my powermasters are actually broken, does anyone repair them?  They appear to be sealed units.

Thanks. 

As, John said! Game over - repair time.

As “BALDOC sez:  Replacement time, Lionel does not repair Legacy Powermasters!  I bet GRJ could if he had a Diagram or Schematic !!!

We repair lots of stuff without schematics, obviously it's a whole lot easier with documentation!

Thanks for the replies.  Since the PWs seem to run the trains OK, I'll just keep them and shut off track power at the Powerhouses.
