Just a ponder, as I put together yet another loom. Occurred to me a coffee ago that the main 30A fuse is actually between the alternator output (joined with the main ECU power supply, etc.), all on the OTHER side of the battery. In other words, alternator output goes through the fuse into the battery and the alternator output will power up the engine electrics in the absence of the fuse. Interesting, but this is how I've wired it without thinking in the past (just as on the bike) on my last 2 looms.
I'd have thought you should have had the alternator output straight to the battery and the ECU and bike electric feeds off the other side of the main fuse.
Anyone else noticed this on a different model/make of hairdrier?

Alternator output on bikes doesn't go to the battery it goes to the reg/rec to be changed to DC about 14v not like on a car. It has 3 phases to convert and regulate before the bike can use it.

I overlooked the rectifier/regulator to make things simpler to question, but it looks like I may have complicated things a tad by doing so. Yep, but the rectified and regulated output from the unit goes straight to the main fuse, out, i.e the other side to the battery. Just seems a tad wierd, but all the Suzuki diagrams I've got square this as the way it is on these machines.
With the car alternator output, and to avoid confusion, by this I mean the rectified and regulated output (on a modern Japanese unit, there's one wire only, serving output function to simply further), this still goes to the battery, not on a main fuse 'protected' side.

It's just something I've noticed on my Suzuki machines, wondered if, say the R1 had done the same. Just seems wrong, works well though.
