Psycho Lionel RS GP9

[trainbrain]

Hi

My Lionel NYC GP9 is acting psycho today. It's #2380 w/Railsounds from about 1996. It was ok until I tightened the motor mounting screw.  It's thru the truck into the 1 Pullmor motor.  Back on the track, it shut down like it shorted the track itself.  The green light on the TMCC base was blinking.  I'm running in conventional.  I polished the wheels and p/u rollers and cleaned the track.  It hesitated, then ran and the horn had a party.  I ran it good up & down a long straight away and noticed the front p/u roller sparking pretty good. Then it shorted the track again.  Any ideas before the shop gets it?

As always, thanks

PS  My other engines run fine on the same track!

Green light flashing is on your PM-1 PowerMaster?  This is what it sounds like if you are running in conventional.  The command base is not ordinarily used for running locos conventionally.

That's a 7 amp short.  Perhaps a wire inside the loco shell got pinched when you cinched down the motor screw... it should be checked out ASAP before causing a TMCC failure to the loco.

Thanks Rob

I'm only using the Powermaster and it always blinks green when a short happens(Derailment, etc). The GP9 seems to short itself so it's off to the doctor.  It starts then dies.  The front p/u roller still sparks some.
