(Also posted at slantsix.com) Stock Voltage Regulators 70-and up fluctuate between 11.5 V and 13.5 V according to OEM specs and experience. Why? All the research I have done says that most if not all Volt Regs for other cars are between 14-15V steady. I am going to switch over to the constant 13.5V Regulator sold by MP if nobody can convice me not to. My car runs so much better when the car is first started and the regulator is allowing the higher voltage. My Alternator is fine, totally tests out, normal flucation at stoplights etc, but otherwise 100%. Tim |

Tim most voltage reg. vary the voltage on battery state and alt output. The mopar stock reg can vary from 11..8 to 13.5 but most of the time it is at over 12 volts. If you have not done this take your alt to a shop and have them to test it off the car be sure the amp load is up to specs. The reason a constant voltage reg is sometimes a problem on a street driver is that it could boil the water/acid out by overcharging. Also the Voltage reg on all MOPAR cars need to have a good solid ground if not this will be a problem Thanks Ron Parker |

The voltage regulators are temperature compensated. Batteries do not accept a charge as easy when they are cold so they need to be supplied with a slightly higher charging voltage. When hot they charge easier so need voltage reduced to prevent over charging/ cooking. Stay with a good electronic regulator. |
