Re: Anyway to check a stator and Rectifier?
I have seen a few in some cases where at idle it was below 14. Mine is about 13.8 at idle. My battery is an original from 5 years ago and have never had an issue. As soon as I bring the bikes rpm up the voltage rises to about 14.3 or so. Even with cars the voltage may drop below 14 at idle. Most bikes don't start making voltage untill the revs are brought up.
The service manual for our bikes says that the voltage should be 14 volts at 5,000 RPM. And that the battery should read 12.8 static with the bike off. I have always been with the schooling that 12.6 is the minimum static battery voltage for a good battery. anything less means that the battery is not up to snuff.
And after double checking the service manual it is the stator that has the resistance test. The rectifier is not testable. the procedure is as follows.
Connect the pocket tester (Ω × 1) to the stator connector probes.
looking at the connector with the flat side down ( tabs on top ) from left to right are probes or leads 1-3.
Lead 1 to lead 2 test resistance= 0.12-0.18 Ω
Lead 1 to lead 3 test resistance= 0.12-0.18 Ω
Lead 2 to lead 3 test resistance= 0.12-0.18 Ω
If out of range the stator is bad. If good and the vehicle does not get 14 volts at 5,000 rpm then the rectifier is bad. This is as per the 06 r6v service manual. It is the same for the 05 and earlier bikes as well.
