I am green and I just bought a early 70's 128. And I love it, but it is coming together with hiccups. The voltage regulator seems to be the culprit. I tested the SG and it responded correctly. The VR that is on it is a 4 wire with lug on the bottom. My problem is the hook up. The diagram shows a ground going from the VR, but from what lug, F?. The VR is capable of being grounded to the frame, is that enough?
I will appreciate all and any answers.
PS I already bought a plow.
