85 R80 charging
We have gotten the R80 running good and decided to check the charging voltage.
The warning light goes off just above idle, but when a multimeter is hooked to the battery, the voltage is only 12.7. If the RPM is raised to 3000, within a few seconds the voltage tops out at 13.2
The battery is new and cranks fast. The owner and I rode 150 miles yesterday with his heated liner on and the battery seems to have been charged.
We started troubleshootng and followed Chiltons advice to scrape the paint away from the rectifier mounting bolts. That made the rise to 13.2 a little faster. We then cleaned the connector on the voltage reg. That made the rise to 13.2 even faster.
Is the regulator doing it's job of not over charging, or should the voltage rise to 14V or so?
