If the ground is bad on your voltage regulator will the sled still start?

Will a sled still start and function without a voltage regulator?

Is there any way to check proper operation of the voltage regulator while it's installed in the machine?

 

[the fix-it guy]

Yes on older machines and I think so on newer models. the ignition system is normally separate from the charging system.

fix-it guy is right.

You can test the voltage regulator by starting the machine and bringing the RPMs up almost to engagement. Then using a volt meter check any solid yellow line for voltage output. It shouldn't be over 14 volts or so. If it's much more than that the voltage reg is bad.

Also, if it is a bunch lower, like 5-7 volts, with RPMs up in the 3000+ range the voltage reg is bad.

Cool, I'll check it tomorrow.

It was suggested to me that the reason my 99 700 kept blowing headlights and such was a faulty voltage regulator, so I got one and swapped it out today...the instructions said to caulk the backing plate to absorb vibration.

Apparently its a wonderful thing I am not the guy redoing peoples bathrooms, because i caulked it WAY too much and it got everywhere and I have no idea if the regulator is even grounded now

I'll splice the yellow wire and check tomorrow

haha

The bolts through the regulator should be sufficient ground.

My 99 700 was doing the same thing plus melting my handwarmers. New regulator fixed it right up
