Title: Charging
Post by: Thomas on June 28, 2025, 06:50:33 PM
Hello everyone! Suddenly the ammeter shows a charging current that depends on the revs. I suspect my regulator has a problem. Am I right?
Cheers, Thomas

I don't understand the regulator. I pressed the two little plates today to see if they could move freely. After that the light stopped working, but the engine started and the fuse is ok. Can anyone give me an idea of what is wrong here?

Thanks a lot, John! I will put it into my files although it'sd for a MCR2 (I have a MCR1). In the meantime I discovered a broken earth wire in the regulator wiring part and soldered it. The cut-off is fine. The reg seems to work again.
