Hi folks, I've been trying to adjust the regulator on my 76 model. The electrical system is all original. When the revs are increased above 3k it is over 15.5V. I've tried backing off the regulator adjustment to bring it down to around 14.5V, but it wont keep the battery charged. It will slowly go flat. It is a new battery. Is a solid state regulator the answer?
