And we are surprised by that ,why ?
Well, I dunno! No reason, other than I'm surprised that everything on the bike but the starter circuit would be running off that one small wire - all the power draw, and the charging. Don't the electrons bump into each other as they cross?
As I look at the diagram, yet again, I see now that indeed there is only one wire feeding the whole system, and that's gotta be it. It shows all the fuses "before" the ignition switch, but they're there.
Seems like this must be the answer - took awhile, huh? I know it's a lot of dope slaps, but think of the exercise you guys have been getting!
Here's another question, while we're on the subject of the UCE wiring diagram - do any of you guys have one you can read? Mine shows power coming (through that little red wire!) right from the battery, through a fuse and into a switched terminal of the "power relay". The energized relay sends that power on to the fuel pump relay and the EFI system. This relay's coil gets power from the battery through the ignition switch and the "kill" switch. The negative end of the "power relay" coil feeds a switched terminal of a second relay, labeled "PG" (Power Ground?).
It's this second relay that has me flummoxed. The other switched "PG" terminal leads to ground, so the "power relay" won't energize unless the "PG" relay is also energized - I get this. The "PG" relay coil gets power from the same source as the "power relay", but the negative end of its coil leads to ground (the same ground from the previous sentence), through the side stand switch.
This is what I don't get - why the second relay? As far as I can see, the only thing it's doing is protecting the side stand switch from is the power relay's energizing current, which would be identical to the the "PG" relay's energizing current anyway, so it's redundant. Isn't it?
Also - according to the diagram, simply disconnecting the side stand switch would prevent the "PG" relay's coil path from reaching ground, so the "power relay" would never be energized - and as we know, this isn't the case.
I know, this is wordy and makes no sense without the diagram to look at - but if anybody does, would you care to try to enlighten me on what's with this double-relay circuitry?
