NAPA voltage regulator by Tony Salvatore
"On a 12V CJ, a NAPA VR503SB voltage regulator ($29) can be used. It's the equivalent of the Standard Motor Products VR124. My bike now puts out a nice 13.7V throughout the rpm range. No more 18+V and boiling batteries! It's slightly bigger in size than the stock one but will still fit under the tank with no problem if that’s where yours is mounted."
"After cutting off the plug, it's the same as wiring up the Standard Motor Products unit. On the VR503SB leads: brown goes to ground, red goes to your diode (marked “+” on the stock regulator) and green goes to the stator. (marked “F” on the stock regulator.)"
