ZW "Multi-Control" TM Controller problem

Classic Toy Trains Forum
1

I have a Lionel type ZW “multi-control” TrainMaster Controller and Powerhouse transformer set, Lionel # 6-22982, with two 135 watt bricks. I am operating it in conventional mode, and the track voltage stays on full power on channels B and D, regardless of whether the controlling handles are turned all the way up or down. I have the transformers (bricks) and jumpers plugged in correctly, according to the instructions, and have rechecked the track wiring several times and still cannot get the voltage to come down. I have also tried the “reset” feature. Can anyone help?

Thanks, Jitney55

Sounds like you need a board repair. There’s a guy, Dale Manquen, in the OGR forum that fixes them, here’s his site: TrainFacts

Great, hopefully he can bring it back to life. The symptoms sound like the driver triacs, which I think he has in stock.
