Both CJs and FSJs have the CVR in one of the gauges, in the fuel gauge and temperature gauge resp. Nominally the CVR makes 5 volts to run the gauges at that reduced voltage. If that's the problem, I'd suggest searching for threads here about replacing the Jeep CVR with a 7805 or 7806 integrated circuit. I've done this to my J20; pretty easy and it works great.
