Power Commander 3 no power (07 Versys)
I have an 07 Versys and just installed a Power Commander 3. Before I put everything back on, I wanted to make sure it powered up; when I turn the key to the on position, there’s no power going to the PC3 (the unit works when connected to a computer with a 9V battery). The dash lights up, and I checked to make sure that the wires from the injectors (the thicker white and red ones) goes to the red wires of the PC3, and that’s all good. The ground is good. When I jump the left PC3 connector (red wire) to the +12V of the battery, the unit comes on, so I know it’s not the wiring of the unit. The bike ran perfectly before this (my wife asks me why if it’s working do I feel the need to tinker!) so I’m sure there’s no issue with the wiring of he bike either.
Now, as I mentioned, there are a few things not plugged in because the air box is still out (no IAT) and the tank and fuel pump are sitting on my workbench. From what I saw in the service manual, the power goes through the fuel pump relay. Would that explain why I’m not getting any power to the injectors (and subsequently the PC3)? I’m not at home right now and honestly I can’t recall if the FI light came on or not.
Thanks in advance for any help. Riding season here is just around the corner as Mother Nature seems to be toying with us (-5Cto -10C in mid-April?) so I’m hoping that I can get this resolved ASAP.
