Ground and wiring help needed.

Try the Rube Goldberg method first. Either hook up two ground wires or one, very heavy gauge wire. Also, though, check the current at the battery while running. It should be about 13 to 14.5 volts. If it's way higher than that you have a regulator issue.

Are the rest of the electrics back on with the new ground wire?

Does the new engine have the same stator as the old one? The voltage regulator/rectifier must be changed if it does not have the same stator. Voltage regulators are sold by the number of "poles" a stator has. You must use the correct VRR.

Also; attach a heavy-gauge wire to one of the valve-cover bolts and connect the other end to a known ground on the fame. For some reason this "primary ground" is not mentioned on gy6 wiring diagrams, and is often omitted.
