Nice job on that throttle, Kevin. I bought one directly from Ken (he's only about 15 minutes down the highway from me), but had trouble when I hooked it up to the layout. I took both the main board and the hand-held back to him and both checked out okay. I had wired it into the layout so that I could select either my MRC Controlmaster 20 handheld, MAW Scale throttle, or Intrakit pushbutton throttles (both run off the AC terminals), or the PWM handheld, simply by flipping a couple of dpdt centre-off switches. All worked fine except the PWM, which was absolutely dead. After rechecking my wiring several times and finding nothing wrong, I shifted the input power to the board from the fixed-DC outlets of the CM 20 to the AC outlets (same as the MAW Scale and Intrakit handhelds) and, lo and behold, worked like a charm. It turned out that the brand new dpdt switch used to control the PWM throttle was faulty.
