This is a problem I just can't get my head around.
With no power going to the track, I can place my RailKing RS3 on the track, turn on the handheld, turn on the TIU, and control the engine fine.
If I shut down, replace the RS3 with my WBB E7 (ERR Cruise Commander, MRC AC Sounder, and an LED headlight installed), turn on the handheld, then turn on the TIU, the engine takes off like a rocket, the readout says 0.0 volts. It acts like it's getting the full voltage from the Z750 transformer (like in DCS mode).
I can back the thumbwheel down and the engine will stop. Move the thumbwheel so the readout indicates 5.0 volts or above and the engine starts to move forward with no problems, like it should.
If I turn off the power, then turn it back on with the E7 still on the track, it takes off again, under full power.
I double-checked my wiring (nothing's been changed since I did the initial install last year). I disconnected the MRC AC Sounder, I disconnected the LED headlight...same results.
I even turned off FIXED 2 and VAR 2 just in case, but if the engine is sitting on the track when I turn power on it flies away.
Any thoughts?
