Hello all and Happy New Year.
I just bought a used Premier NYC E-8 20-2317-1 which has the 5 volt PS2 electronics. All sounds and features work fine except when I move forward or backward at 1 mph the engine takes off at full speed. When I change the mph to 0 or hit the direction button the engine stops as it should. The engine runs fine in conventional mode. I have changed the sound file, thinking it might be program or flash error, that did not fix it. The tach reader is right up against the flywheel, I compared the distance with another working Santa Fe E-8 PS2/5 volt engine and it's the same distance. I changed the tack reader, by removing it from my good working Santa Fe E-8 installed it on the NYC E-8 and still did not fix it. I even changed out the voltage regulator (though I don't think the VR has nothing to do with speed control), that did not fix it. All wires are snug and not loose, the tach reader is not loose and is very close to the flywheel and the tach reader tape on the flywheel is very clear, clean and no obstructions. Any help would be greatly appreciated, thank you.
