looks like someone hooked up a 180watt Powerhouse to my old PM-1. With no switch on the PM to change over to 180, it's toasted. On conventional mode it will not drop below 50% power. I have tried the AUX1, 0 reset. Has this happened to you?

You probably have a shorted power FET in the output.
Just hooking it up to a 180 brick won't cause a problem. These things can also blow with a 135W brick.
I repair Powermasters. If nothing else is damaged, parts and labor to replace a blown FET is $25, plus shipping.
My repair also includes adding a TVS across the FETs to minimize future problems.
thank you, I am going to borrow a PM and make sure I have no other problems then send the bad one to you for repair.
