Voltage fluctuations
« on: March 15, 2018, 01:13:42 AM »
Just took "Lucille" out of winter storage and I'm seeing fluctuations on the dash voltmeter--nothing big, just annoying.  I checked the voltage at the chassis batteries and my voltmeter is showing about .3 volts fluctuations always between 14.2-ish and 14.6.  Curiously, the Silver Leaf is steady--no flux at all.  Chassis batteries are about four years old, and the alternator is less than a year old.  Seems to disappear at cruise rpm--more noticeable at idle.

Take a look at the connections on the batteries.  Clean as needed but look at the battery temp sensor and be sure that makes real good contact so it is sending good info.
14.6 seems a bit high.

Good luck
