Default Air compressor wiring (speedaire)(dayton)

Can anyone on here help with the wiring on a speedaire(dayton) air compressor? There are no tags on the motor or compressor so Grainger cannot help with wiring diagrams. There is some sort of switch or treminal block missing in the junction box. The wiring was done by previous owner. I tried wiring the two wires with the missing connection directly together but it blows the breaker. With them disconnected nothing happens at all. The wires appear to come from the low oil cut off switch. Any Ideas. The ground wire is not wired to anything at all in the present configuration.

1) get a Grainger catalogue and look for the model closest to the one YOU have.
( is a start but you need the hard copy; better yet an older one)

2) plug in the model # that looks closest here: and then poke around.

3) while you are looking for the grainger catalog look for a basic electric motor book too.
