gp9 problem

i am having problems with a gp9 built 1996 with tmcc it has the older long boards in it. after running 10 min give or take it stops and this is my only engine that does this. Here is a video of what happens.

Sounds like a heat issue, did you try running it without the shell?

[bigdogjeff]

no because there is the light atached to the shell and a ground wire that is soildered to the shell

Even though O and HO are two different worlds the electronics are very similar. I have a loco that has very little space inside and heat builds up quickly. This was causing the DCC chip to overheat and it would cause the loco to do strange and not so wonderful things, like stall, slow down or just go dead. I solved the problem by cutting out the molded on radiator fans and installing fans with see-through grilles. This gave the heat a way to escape and the problem went away. Maybe you could do the same?

well i may of found the problem i was running it and when it stopped this time the engine was still spinning come to find out the plastic gear is stripped in the power truck

okay that about sums it up I have the exact engine and my problem was the elctronic e-unit board I think lol anyway got it from boxcar bill and put it in mine and all is fine. but mine would either stop dead or would go like a bat out of H&!! burnt up two powermasters that way befor figured what was going on.

ok here it is i sent the geep to lionel and they put a new metal gear to replace the plastic gear and the said found no other problems and sent it back to me and i ran for 1 hr straight pulling heavy metal cars to put load on it and no problem so it was the gear causing all the problem with it stopping.
