It should be a cable that looks like an oversized telephone cable. I can't really tell by the description of the problem if you just can't remember where it plugs into or if you've lost it altogether. There will be a circuit board in the base of the treadmill that will have something that looks like a phone jack port on it. That's where it will plug into. There should only be one port on the lower board that will accept that style of plug.

Precor error 15 input voltage

Precor Error 15, AC Input Voltage Too High Probable Cause 1. AC input voltage is incorrect.
2. AC input voltage transients. Transients can be caused by lightning strikes or by other pieces of equipment sharing the unit's AC power.
Corrective Action
  1. Verify AC feed into the building's circuit breaker is correct and connected to the proper transformer tap.
  2. Ensure the AC grounding for the unit's outlet is good and verify the unit is connected to an isolated and dedicated 20 amp circuit.

Need to disassemble a precor 9.31 to move to a new location. What tools do I need and how to do it?

Remove the motor shroud this is done with a set of allen wrenches, remove wire harness from the lower pcb, then on the console tower which is bolted to the frame with (should be ) 4 allen bolts on each side. Have a additional set of hands so that the upper tower does not tumble down.
