I would call this more of an exorcism rather than resurrection. Last week my MTH PS2 260E began acting wildly when powered on the track...high speed lurching then a slow resumption...then repeat. It must be possessed.
I checked the usual...clean wheels and track...has a new BCR2..adequate steady power ...proper lube.
I use PW transformers so I got my Z1000 floor layout power hooked up to the track and sent a speed control off code...smooth operation then. Ahhh...I cleaned the speed sensor...no change.
Checked with the MTH board...the expert said I was looking in the right area.
Most of you who know me know I am a pre/post war guy. This is all new.
I looked at the sensor and it was a tilted up a bit. I tried to move it..no go. I then wedged a small piece of clear plastic behind the mount (see pic). This forced the sensor closer to the flywheel with a better angle. I hope it holds.
BACK IN BUSINESS. It works like new.
In summation...deductive reasoning...forbearance and just plain luck prevailed. I feel better now.
