FA 1 WBB Shorting

See if anything else is off the track, or something fell onto the track.

See if the coupler thumbtack is out of position and touching the center rail.

Take your time and look closely at everything on the bottom.

Take everything off the track and see if the problem with the transformer still exists. If so, something is on the track, like a black screw that is hard to see.

After checking the track and the externals of the loco, if you still have a problem, then something may have happened inside the loco. Take off the shell and look for any loose wires. Look at the circuit boards inside for signs of damage; the derailment may have damaged the motor or board(s). Check the motor by disconnecting the wires to it, and by applying power from a 9 volt battery to the motor terminals. It should run. If the motor runs, and the loco still shorts out, the electronics smoked.

Thanks guys, I followed all the advice, the problem was a loose wire, not disconnected but loose, I tightened the screw and now the engine runs great.

Again thanks for the advice

Brent

Good job, Brent. You were fortunate this time.
