If anyone has a (working) OEM regulator, would you check the voltage at the battery terminals at idle, 1500 rpm, 2500 rpm, and 5000 rpm, please?

The electrosport regulator I just installed maintains ~13.6V at those engine speeds, I'm curious what the OEM version does.

Also, anybody with any other brand, same request.

thanks.worm

 

Sorry, I don't have a stocker. I replaced my melted one with a gixxer unit a couple of years ago along with adding a voltmeter. It pumps out a steady 14V above 2k rpm and a few tenths less at idle. If the fan comes on at idle, it drops down into the 12's.

I think yours should flucuate at least some.

A R/R consists of three on-off switches (diodes) that shunt current based on need, not RPMs. When charging, your charging output will be about 10 volts if one of the circuits is compromised, about 5 if two are.

Are you having a problem, or just wondering?

 

I was just wondering. Seems to me if the stator is supplying sufficient voltage and current, then the R/R should supply a constant voltage across the rpm range (since that's what I'd expect a regulator to do). So I was happy when I measured that constant voltage from idle to 5k rpm.

But it is at odds with what the local shop claimed the stock R/R would put out, which was basically:
battery voltage at idle
13V by 2000 rpm
15.5V by 5000 rpm.

I'm of the mind that yet again the shop was FOS, but remained curious enough to poll the forum folks.
