I just got my new '17 501FE. I gave some first impressions in a different post so I will not repeat. Short story is I need a good soyrce of KEYED 12V for my GPS hookup (by keyed I mean it turns off when the key is in the off position). I need someone smarter that I to interpret that wiring diagram... I have the service manual and printed the schematic. I can't make much of it -- I am very good at wiring diagrams and have added keyed 12V to many other bikes but this one has me stumped. The ignition switch on and off positions don;t seem like they take 12V and connect to anything - I think I have heard elsewhere that the ignition switch can be entirely removed and two wires connected or one connected to ground to make it a "regular, non-keyed dirt bike (an explanation of that would be great). It seems like this bike lets the ECU control everything and that there is no easy 12V for accessories available, per-se (I hope I am wrong). As part of a desperate experiment (I was running out of time before riding), I took my VOM and probed the wiring harness behind the headlight looking for a hot wire when the bike was running. The strange thing is that many were hot but only periodically!! I would plug my GPS into them and it would power up but then every 10 seconds or so say power was lost only to have it return a few seconds later!! Sure enough, if I measured any of these potential wires with my VOM they would show 13 of so volts for a while and then drop to zero for anywhere from .3 to 1 second before returning back to 13v. Very strange behavior and they were all sort of doing this. I did not haul out the oscilloscope to see detailed behavior but I am willing to do that... I presumably was tapped into something in the ECU. Ok, so that was some bad science and I am willing to move from the errors of my ways with your help. If you can provide insight (along with location on the wiring diagram and wire color) of where I might find reliable 12V when the bike is running, I would be grateful. Please don't say "just hook it to the battery with a switch - that is not my style or the solution I am looking for). Presumably others have interest in getting keyed power for their goodies too. Thanks for your constructive responses.
