My Galaxy was missing the relay; I got a relay installed, and it worked as expected but it seems to be burning up a little bit ; the plastic base of the relay has melted slightly. And it smells a little Sulphury when the game is on.

Is this likely just a tarnished relay socket causing excess heat? Or....?

Basically just need the relay part #.

Also, I'm assuming I can just move the blue wires back to the rightmost tabs & remove the jumper - if that's wrong, please set me straight

Quoted from G-P-E:

Ah -- found photo.
*Stern* Galaxy with relay near rectifier board - GI Relay.
Powered from A2J2-2 --> solenoid power.
Use 48VDC relay:
Omron LY2-DC48 or Rayex LB2-48DS

Awesome, thank you!

Where'd you find that info, just for reference? I didn't see it on the schematics.

Great Plains doesn't sell that one by chance, do you?

So, I got a relay installed, but it seems to be burning up a little bit ; the plastic base of the relay has melted slightly. And it smells a little Sulphury when the game is on.

Quoted from G-P-E:

Yes - that was me that posted #4 above... I wanted to make sure but could not find that picture again.
So I did go through the connection diagram for Galaxy. The relay gets its power from A2J2-2 which is rectifier board, J2, pin 2 --> 48VDC.
Relay needed for replacement:
Omron LY2-DC48 or Rayex LB2-48DS

So, I used the Rayex LB2-48DS from GPE, but had the relay get toasted.
Does seem like you've pointed me towards the correct relay.

I'm wondering if I rewired things wrong.

Anyone got a picture of the wiring going to the socket that the relay plugs into?
