Ok, I can't find any diagrams showing the wiring in the PT for a Golden Eagle 1102 engine. Since on the GIC website http://goingincirclez.com/TycoTrains/Guide/PowerTorqueRepair there IS mention of the reversing light for a Super 630, I have to assume that there is something special about that version that allows the lights to work in forward and reverse independently. But unfortunately GIC's site didn't provide that wiring or PT picture on his website. Do you have one handy to show us? I'm curious as to how it works. I don't have any of the 630 version engines, only 430. And of course all the Tyco diagrams on HOseekers is all 60's and very early '70's, there's nothing showing the later PT layouts.

| I'll see if I can dig mine out and add an addendum to the repair guide (which has been seeing a lot of action of late). IIRC it used diodes. Also a rare crowing moment for Tyco as they were possibly the first company to do this in HO scale - in 1978. Who needs DCC? ;)

Ahhhh, ok, that makes sense, because there's no WAY a simple bulb will only work one way unless it's wired special. I thought it had to be something like that. Since I don't have a 630 (yet), I have no way to look at the PT to see how it works. Thanks for clearing that up somewhat. I await the diagram ( in your spare time ). Much obliged, Tyco guru.

It'll probably be a little while before I work these into the repair guide... in the meantime I'm sure these pics won't need too much explanation around these parts.
Reversing 630 (note the rear of the loco is shown):
Reversing GG1:
The diodes are mounted to a fibercard (NOT a PCB) in the center of the loco. Otherwise the wiring is much the same as the 630 - the diode is simply in series with the bulb.

Excellent! I see how they're mounted now. That should clear up the installation , now all I need to know is what the diode value is.  thanks for your input, Tony. Much appreciated.

I like 1N4001 diodes. They're an easy size to work with, inexpensive and available at Radio Shack. If you want to buy in bulk, check out Mouser at $0.20 each for 1 and the price goes down for quantities 25, 100 etc. They'll ship USPS Priority, so you can avoid over inflated shipping charges like those from our favorite hobby suppliers:

I can get those from work, either off obsolete PCBs or elsewhere. Thanks for the tip. They are pretty common.

Eh, the diode is behind the bulb, where the wire leads into the bulb ( on the 630 ). It's black like the wire, so not easy to see, unless you know what you're looking at. The Diode is soldered directly to the bulb in this case, then the wire to the other side.
