So I have a Speedaire Brand Air Line Chiller (for use with my compressed air lines to remove condensation) that badly blew out its relay about a year ago. Trying to find replacement relay was hopeless. Model discontinued. Someone on a ask a repairman website pointed me to a whirlpool 66857-2 Refrigerator Compressor Relay as something that should do the trick as a replacement part. It has taken me months to get this far and now that I try to install it I have no clue which wires go where. The relay has no markings that I can decipher. It has three contact points.

I have 4 wires to connect:
1 is the ac from the power supply
1 appears to be the power to the fan motor
2 come out of a philips brand electric start motor, used, I assume, to kick start the compressor.

I am no appliance repairman, but I am still handy with these kinds of things, but with no schematic or markings on anything I haven't a clue.

Attached are photos of the new relay and the melted one while it was still wired. It just isn't as simple as connecting the same wires to the same place on the new relay.

Thanks
