Flashing Low voltage warning .

[vipers95]

My 2017 CTD started doing it on Saturday maybe ever 20 minutes or so it would flash low battery volts. Sunday got worse about every 10 minutes. Used it today every 2 minutes. Called the dealer he can get it in about a week. Check all battery connections and the 250 amp connection all tight. Checked the plugs in both alternators, they were seated. Passenger side voltage stud was a little loose. Drivers side was 4 turns loose. Tightened it all back up and no more problems.
