2005 KZ 1000P. 70,000 on the meter,,, assuming it is the original.
Trying to get my sons newly acquired KZ close to right,,, it was seriously neglected. First Kaw I have worked and first time I have had a motorcycle charging circuit act like this.
Checked all wiring and connections especially on the Brown wire. With headlight off it's 14.6... headlight on 15.1. Hooked in another regulator, (off a Honda) same thing. Stater shows good, 60-70 vac per phase. Coils 5-6 ohms, no grounds per megger. There is a 0.5 to 0.7 voltage drop from the battery to the sense (brown wire) at regulator plug. Checked the regulator rectifiers. check good on the multi-meter.
Strange thing is it doesn't jump to 15.1 when I turn on the driving lights that are on the fairings auxiliary circuit. (2 @ 35 watts). Only the headlight which I believe is 55 watt.
No offense to the Kawasaki crowd,,, but I'm not real impressed with the Kawasaki wiring on this bike. Appears they went the cheapest possible using 16 and 18 guage wire. This particular voltage travels all the way from the battery to the Ign Switch then all the way back to the fuses. Unnecessary voltage drop. Then One teeny little wire from the regulator to charge the battery. Even cheapo Honda used (2) 16 guage wires here to carry the current,,, and it was fused!
Well,,, 15.1 isn't super high but I am used to 14.4 to 14.6. What say you Kawasaki experts? Should I pop for a 775 Shindegen? About 200 buckeroos! but eliminates the sense wire.
