SV650 Curvy - Voltage Regulator / Rectifier supplier?

This seems a fair priced one

Just check with the seller it is marked FH008. If you do a search on this forum for FH008 you will see a few have been fitted.

I fitted a CBR600 one to a curvy too. I cant remember the year it came off but it cured the problem and lasted until I sold the bike about five years later.

I've got a mofset r/r doing nowt in the shed. Bought one for a job that never happened

Another possibility - series regulator:

Hi

I have installed a second hand rectifier which gave the correct readings when on the bike it has been removed from.

When lights are off, 16.5 volts at idle and hovers around 17v at 5,000 rpm.

When lights are on, 13.5 volts at idle and just below 14 volts at 5,000 rpm.

The results with lights on are within range, whereas lights off is outside acceptable range. Switching between dip and main beam does not change the voltage. Any indicators as to what the problem is?

Thanks,

Hi,

I fully charged the battery and the charging system behaves the same.

I fitted the previous rectifier back on the bike, and now it is behaving as previous with poor charge.

Before I resort to buying another rectifier, can a rectifier be faulty and cause over charging? Or should I be chasing through the motorbikes electrics?

I have also checked the Stator output again and now one of the three connectors is showing a couple of volts less than the other two. Can this be causing the excess charging?

Thanks,

Yes.

Anything 15V upwards will fry the battery.

You need to be a little careful about testing, though. If the R/R has been detached from the wiring loom before testing, it's possible that you'd read a high voltage when there's zero load. At least, that's my understanding!

Yes. The R/R does two jobs. The Rectifier part changes AC current from the Stator into the usable DC voltage required by the vehicles electrical components and the Regulator part meters/limits the Voltage so is doesn't burn out the components.

Buy a new one. Especially if the second hand one was an sv650 one, they're notoriously bad.

I fitted a tourmax brand new one designed for CBR iirc.

buy the proper kit = working bike


or dont but the proper kt = fukered bike


the choice is urs. welcome to the rip off bike world.
