Mosfet is in

Quote:
Mosfet is in and I have 14v at idle and 14.5 at 5k
Thanks for all of the help guys!
Seen this statement from a member on here and have some questions maybe someone can clear up for me.

#1. I was always taught ( in a technical school) that 13 volts to 13.5 volts was normal charge to the battery. 14 to 14.5 seems a tad HIGH. Has anyone here checked to see if their battery is HOT to the touch after shutting the bike down? Over charging has bad effects on some batteries.

#2. Does the Mosfet change allow more wattage to be used for optional items on the bike. If im not mistaken, i think i read somewhere in the forum that 90 Watts was the max usage allowed.

Please Chime In !

What most folks have done to pick up extra wattage is to change out bulbs to LED. You can pick up some watts there. I even went with a HID conversion so I'm using 35w instead of 55 for the head light.

I seem to remember the usable wattage for the bike was around 70 watts though.
Since my mosfet was installed I'm running a strong 13.5 with everything on (execpt running lights) at idle. Radio included.
The running lights are not an issue when I'm riding & it goes down to about 13v at idle.

cars, 13.5 is decent, its actually closer to 14.5 on computer controlled cars where the electrical system needs more juice... the Kawasaki mnaual says that the R/R should put of 14.5 volts at 5,000 rpm.. that is where we get the 14.0~14.5 volts from for determining if the stator/r/r is working or not

The manual is also not figuring on a Mosfet R&R. It's basing it on the old Shunt style. I wouls have to guess depending on the Mosfet R&R you buy, you could get different readings.

The popular FH012 seems to give a good 14 v reading however the one I bought used on Ebay FH001 came off an 06 Yamaha Road Star XV1700. I figured if it was good enought to handle the electrical system of a 1700, I should be good. And I am. No complaints.
