Re: 71 Blue Jay

So I’m having (been having but avoiding) issues with the external voltage regulator (EVR). I replaced the old one about a year ago because it stoped working. The new one is points style regulator like the old one but it make so much noise. Didn’t think much of it at first but then the noise became sporadic.

I checked the voltage when it’s not making buzzing noise and it a healthy 13.5 or 14.5, can’t remember exactly now. It was good. Turned the engine off and restarted. EVR is now buzzing. The voltage from the brown wire in the EVR jumps between 8.2 & 11.3. The voltage at the red wire of EVR 14.8-15.5.
I’ve added lots of grounds, checked all the wires I can and patched and taped. Swapped the alternator. Got a new battery. Still not working correctly.

In reading about everyone’s EVR problems on here I’m thinking it isn’t playing nice with my HEI distributor. I may need to run a new hot wire to the distributor. Just ordered a solid state EVR to see if that will work better with the HEI distributor. If not I’ll reluctantly have to upgrade my alternator to a 12SI doohickey.
