I replaced the rear coupler on my Custom Series 1 Hot Rod GP9 6-18575. When placed it on the layout, I got nothing but static through the speaker. I opened it back up and found one of the pullmor motor leads came of. It appeared to short to the side of the motor. I reconnected it. I have the sounds back. Motor, horn and bell in conventional. I can fire the front and rear couplers with the DCS remote but the lights don't operate and the engine will not move. In conventional, the engine revs up higher with higher voltage. I can spin the motor so it is not a mechanical issue. I assume something on the board shorted out. all connectors are secure and plugged in properly
I have a few questions. Lionel shows the board but as blank. The sounds are custom to this engine and I don't want to lose the sounds. What exactly does the upper and lower boards control since the coupler connector is next to the lighting connector. Also I found that the cam on the axle has a crack and spins on the axle shaft. I assume this is speed sensor for TMCC to control engine revs when operating TMCC
Thanks Greg
