Over charging ?

Post by **Garym** » Sat Feb 09, 2008 8:27 am

My 1970 Mog seems to be overcharging.
I have renewed the voltage regulator and replaced the bushes in the dynamo because the red light was constant on the speedo,not charging.
This obviously solved that problem,but now when I start the car,on full choke the volts dial in the car goes up to the red,on tick over it goes down to normal but when I rev ,it goes back up to red,and the lights get brighter.Does anyone know the problem and how to solve it ?

Forget the in car volt meter, they are not that accurate. Using a digital voltmeter set to 20 volt range, connect it across the battery. Expect to see about 14.5 volts when engine revs are over 2,000 RPM. There's a setup section in the Haynes Manual for the regulator cut out etc.

Sounds like a problem with the regulator which you say you have renewed. Change back to the old one asap!
