Hi everyone; I have a question about my 89 Kawasaki Mojave, what does the voltage regulator do, I thought that had to do with a battery.

 

At high rpm's the alternators (thing that generates electricity) output can reach 70-80 volts. At this voltage the alternator would melt (brushes) and you would fry the battery.

The batterys voltage should be 12.6v with no surface charge. The regulator will limit to 14.4v, as this stops the battery from gassing / shedding too much. If possible you're better off charging the battery up to 15.3v every so often. You will have to top it up fairly regularly.

If it's agm / gel don't over volt it (stick to 14.4), as you ruin it.

 

This bike doesn't have a battery , did the later modles have battries?

 

regulates the voltage going to your lights

 

Sorry I'm used to utility quads, which are all electric start etc.

 

No Mojaves have batteries. I have an 03. Less stuff to break down

 

You try pull starting a 220 bayou in sub zero temperatures with no compression release. Now tell me you don't want electric start!

 

I don't PULL start... I kick....much easier..lol

 

So , guys what does the voltage regulator do on a bike with no battery,

 

Regulates power to your lights.
