Hi Everyone! Thought I would try here for some advice. My 2020 Ram 1500 has had intermittent high voltage. Started with the battery light coming on and speakers would pop. After the first time, I started watching the battery voltage digital reading and it fluctuates between 14.2 to 14.7 volts. I have seen it go over 15v when the lights come in. I have connected a volt meter and was able to verify the sensor is reading correctly. A restart seems to clear the light, but it happens 1 or 2 times a week. I am thinking it is a voltage regulator but have researched and saw it could also be the ECM.
Does anyone have any thoughts and also does anyone know if the voltage regulator is built into the alternator?
I greatly appreciate the input!
