It should be between 13.8 and 14.2 volts. 14.2 max at fast idle (2000 rpm). Anything over that will probably boil the acid in the battery. Make sure you don't over fill the battery if you are adding acid or water to it. Been a very long time since I have done any auto electric work, but for the system to charge that high you would have to bypass the regulator. See if you can find a good auto shop that works on electrical problems in your area and give them a call. Shouldn't cost much if anything to have them check it out.

Fast idle/charged batt (should already have that )/lights & heater on, check voltages/drops/ground side also. Blue/green wires go to either alt field terminal. Want switched 12V "blue" to reg and T to either field terminal and green from reg to other field terminal live every 24 hour block of time like it's your last day on earth
