The leafs of the top switch are two sandwich boards apart. Although clearly not closed, the switch reads as closed testing from lug to lug on the multimeter.

The only thing I can think of is that they are connected through the screws. The only stacks I've taken apart were Wms, which had plastic insulating tubes, so if Gtb is the same, it can't be the screws.

I'd appreciate some guidance before I take the relay apart probably for nothing.

thanks!

If you think it’s a screw, take one out at a time, and measure resistance.

More likely there's a nonobvious path through other parts of the game. For a reliable test of continuity, unsolder at least one of the wires.

Yeah you can never really trust a continuity test that comes back positive on an EM. Not to mention that many meters treat even 10-20 ohms as 'continuity' when most coils in an EM measure less than that

See, I know just enough to confuse myself. Thanks very much for the tips!

Hard to tell but just a thought…looking at your picture I don’t see the side of the top blade closest to the wire as I do the rest of the blades in the stack. Could be something, could be nothing.

I’ll loosen he screws and make sure the switches are all lined up.

Which relay is it on your schematic? In many Gottliebs, there will be an open switch and a closed switch from another relay in parallel with each other, making it so that the multimeter will read them as a short
