So your saying I should ignore the installation instructions that came with the relay and basically hook it up just like the old one was connected, right? Actually, the relay instructions may be illustrating the same hook-up that's in the Shopsmith anyway. It kind of makes sense as I don't really kn...

Then is the yellow wire the lead to the motor start winding? I've procured a Mars 19004 and am unsure which terminals to connect the motor wires to as it appears to be different than the(RBM, I think) relay that came on the AO Smith motor. Terminals 5 and 1 on the original relay are definitely acros...
