RCVR board Looking for help

Just PM'd you.

The pins require a little more heat than you'd usually use on a PCB, I find I need 600F-650F to remove those cleanly.

Ray,  I have those pins/connectors.  Not really too hard.  I use my Weller temp iron (good one) with adjustable set point.  I have done them on boards similar to Lionel one.  Not too difficult.  

I can bring iron down or some arrangement.

The one thing about the Lionel receiver board is it apparently has a an internal ground plane that soaks up heat, so a bit more heat it needed to free the pins.

Update June 14 2024:

A club member repaired the pins on the RCVR board, removed the old ones and installed new pins.

We tested the engine with the original Legacy mother board. The engine only responded to ID 99 and ID 1. We tried to reprogram the engine to several other ID's, but they never took.

So we thought maybe a bad mother board. He had a spare Legacy board, which we installed and then we installed the repaired RCVR board. Still could not program the engine to any other ID. It only responds to ID 99 and ID 1. The new board numbers matched those of the original board.

Thinking that maybe there may be a malfunction with the PROG/RUN switch, I made a new switch. No luck.

So now I am wondering, could the issue be with the RCVR board? Does the RCVR board play any roll in programming an engine?

The top receiver board does not store any data, so I think maybe something is still amiss with the receiver board.  Did the main RCMC work with a different RCVR board?

I have a steam loco that had the same thing happen. I simply soldered three individual wires from the bottom piece to the top piece. The pins are obviously a weak spot of these boards.

There was some boards from around that time frame that wouldn't keep a ID change, or the Prog/Run switch/wires aren't actually putting it in programming mode.

I’ve done this quite a few times now with great results ……IMO, it’s the least invasive procedure for those crummy pins…..leave em alone, and go right around them,…..
