horak8,
Welcome to FTE and the IDI diesel forum.

Don't know if I would call the sound like a compressor, more like a coffee pot.

After an hour or so, you should feel some heat if it is working.

Hmm, mine just makes a hiss, kinda like a low LPM HHO generator. O'reilly's can order a new cord if you are thinking yours is shorting out.

Try this test......

First make sure the BH red power plug is in the BH, then do a continuity test with a meter on the main plug wires at the grill. If there is no continuity check the wires for breaks just behind the 120V plug. Pull on the wires and you can see the break as the shielding gets smaller, cut off the end. If the 2 power wires now have continuity through the BH just replace the 3 prong plug.

What coolant do you have installed......

If you have a ground fault recepticle the breaker will trip if there is a problem.
