i have 2000 jeep grand cherokee laredo and my alternator charges at 13.6 at idle i know alot of people would tell me thats a good thing but i want it to charge at 14v i hooked up a dmm to it and it was charging at 13.6 just regular at idle no electronics turned on so i turned on all my electronics such as defroster headlights , and ac/ and heater and radio and also the fan was on for the radiator and it was still the same ... then i accelerated to 3-4000 rpm and the voltage went up to 13.8 does anyone know if this is normal or is it a bad alternator? and is it possible if go get it rebuilt and tell them if they can add more amps or something to make it charge better like change the voltage regulator in it?
thanks to anyone that helps and also i got no electrical upgrades yet and the battery is a wet cell battery probably will upgrade to a deep cycle dry cell later .
