Our club has tasked me with repairing our GP30. I think at some point someone has switched the wires around and I would like to see a picture of the decoder of an operating engine to check the wiring.
This engine is probably about 14 years old. It has a QSI HO140F34 GP30 decoder in it. If anyone has a picture showing which wires plug into the proper sockets, I would be very grateful if you could post a picture.
Thank you, Joe
Hello, Joe
I recently installed an ESU Loksound5 into a "vintage" L-L GP30:

I'm not sure why you would have difficulty sorting out the wiring. Motor + is on the bottom brush, motor — on top.
IIRC, Right rail pickup is through the frame and left from each truck.

If you need further info let me know.
Good Luck, Ed
"Old" here I think is a relative term. I believe the OP is referring to the Walthers version sold factory equipped with a QSI decoder.
I found a picture which show exactly which socker ont he decoder is for which connection (track, speaker, motor, etc) but I cannot post it here because it's on a competing forum. OP, check your PM, I will link the thread which has the information you need.

josephbwThanks a lot Randy, that was exactly what I was looking for.
The links I posted were of no use?

The connector locations on the Titan appear to be different than those on the original decoder. Comparing the image from the article I found with the diagrams on Tony's.
