I believe I found my problem. was at the airport yesterday. Sure enough, the wire coming out of the regulator that should be going to " Earth " was routed to the positive post on the battery.
I replaced the battery a few weeks ago and I am pretty sure I reconnected all the wires back to where they were when I took them lose from the old battery. So either myself, or the previous owner put that wire on the wrong post.
It would be easy to do... All 3 wires coming out of the airplane side of the regulator plug, they are all yellow wires. One going to fuse box, one goes to + on battery and one should go to ground.
Put the ground one from the positive to negative post, rolled plane out and tied it down and ran it up. Was seeing up to a little over 14 volts at 2500 and higher rpms. And tach was smooth and steady unlike before, and seemed to be no noise in the radio either. Fingers crossed this is now fixed.
