help with mosfet upgrade

bought a stator from tim parrott and regulator / rectifier from Jack Fleming finally got bike all back together thank goodness today. I followed Jack flemings installation guidlines to a tee pretty straight forward stator wires to 3 wire harness from the regulator rectifier then right to the battery. Getting solid 14.5 at battery awesome! Checked everything out electrically found that front headlight not working at all. I need help with getting this striaghtened out so i can get sticker and ride! Any help would be appreciated

I believe that one of the wires coming out of the R/R powers a latche headlight switch/ relay. You will need to fake that wire out somehow.

It is the yellow (not striped, pure yellow) wire running into the junction box that triggers the headlight. This wire is driven by one of the legs of the stator, that is split off in the wiring harness behind the scenes.

You need to splice that to a leg of the stator. I have an install post I made here detailing my install.

Yup, it's an easy oversight. I went thru it too. Don't worry about the lead from the stator going to the junction box. As Thtanner said, it's how ma-kaw originally had it. We just don't see it.

What I did when I installed my mosfet and new Stator is I hooked the new stator wires to where my old stator wires connected (bullet connectors ) and used the stator wires from the Old R/R connector for the new R/R connector. As long as your original wiring is good

I do still need to get rid of those bullet connectors and use a solder joint instead. Advice ive seen on here and agree with.

When helping pitdave and gcextreeme, i posted how to make a pigtale that would convert the mosfet r/r to our stock r/r harness. this would eliminate the headlight issue.

Can't find the thread, but HERE is the link to the pigtails.. you would need the MOSFET R/R Battery and Stator (Black and Grey Connectors Respectively) (top of the page) and the Generic 5-Pin COnnector at the bottom of the page.

to wire it all up:
White wire goes to Black Connector Positive and Stock R/R Connector B Terminal (bottom left)
Black Wire goes to Black Connector Negative to Stock R/R Connector G Terminal (bottom Right)
3 Yellow wires to Grey connector and stock R/R Connector Top Terminals (doesn't matter which one goes where)

Plug the black and grey connectors into the Shindegen MOSFET R/R and the white plastic connector into the stock wiring harness. Test for 14.5 Volts through all RPM ranges

***NOTE***
the Lower middle connector will be left empty on the conversion harness, and might want to be filled with silicone to prevent corrosion and water damage.
