Over charging issues 16 + volts. Never really bothered anything until now . idles on 3 cylinders 4th cylinder kicks in when you start to go, tachometer is all over the place and the fish finder went haywire I know these motors have a rectifier and not a regulator other forums are saying to change to a aftermarket regulator 090-5 not sure how to go about this or what wires go where. If anyone could help it would be appreciated. Dennis.
