The jet pump wires connected to the circuitboard of my Hot Spring Sovereign appear to have gotten so hot that melting has occurred. What could have caused this? Could it happen again? What do you suggest should be done to replace the wires? Photo: http://imgur.com/ZkS23jF Thanks

Hi, Three wires are disconnected from the circuit board near where external power comes into my Hot Spring Sovereign. The wire colors are green, white, and black and appear to run to the heater. Where should these wires be connected? Terminals P2 and P3 are open, and the GND hole appears to be missing a screw. Here's a photo: http://imgur.com/PKHGaY8 I don't have the manual and am not sure what year the tub is. An electrician told me that if it's 240v then it doesn't matter which terminal black or white go to since polarity doesn't matter. It would be nice to see a photo of what it's supposed to look like. Thanks
