Reply to "MTH Z-4000 powering Lionel powermaster - no sound on Proto one - why ?"

Fred HollidayOGR Forum Member

I started up my PS1 engine on a a 400 without the power master in the circuit. After it stared and the sound came on, I then had it wired where I could change a power with the power master installed and ran it from there. It ran fine with sound. I had heard that MTH had the PS1 locos to turn off the sound if it sensed a Lionel power master. I don't know ir that is true, but the engine worked the way i have described.
