Re: Stator and Rectifier help
Good work, almost there.
You haven't mentioned it, but the battery has to be fully charged and let rest for a couple hours before testing the voltage across the terminals at 5k rpm. You mentioned voltages when the battery is disconnected from the tender, but time is not mentioned. 13.9V is low for a 5k reading, but that last test to be sure is in the pic I am attaching.
The reason you need to do the last test is because you are now testing the rectifier as an isolated component. When the R/R is connected normally, the battery (and many other connections) now play a part in the circuit. If the R/R is normal, that 13.9 could still be the result of something else shitty- like corroded connections, for one.
If the R/R tests out of spec with the chart, it is already, of course, past it's best-before date. If she's buggered, replace it, but you also now have to re-test the battery, too. Let it sit overnight and test the voltage. A knackered R/R can knacker the battery. The generator is verified as already within-spec.
This, of course, is assuming that when you tried to start the bike, it at least primed the fuel pum and clicked the starter solenoid when you pushed the button...
