grinchsr 591 #1 Posted June 25, 2020 My 1995 520 is sending 14.5 volts back to the battery. Is this considered over charging? I checked it with a DVOM. Share this post Link to post Share on other sites
lynnmor 6,698 #2 Posted June 25, 2020 Should be 13.6 to 14.7, so you are good. If you run many hours per week, then maybe it could be considered overcharging. Check periodically to get a better idea of any changes. 5 Share this post Link to post Share on other sites

Bill D 1,577 #4 Posted June 26, 2020 Ray, My 416 shows the same voltage when charging. I think it's an Onan thing. My Kohler shows 13.8V when running. Bill Share this post Link to post Share on other sites
grinchsr 591 #5 Posted June 26, 2020 I guess I have to agree it’s a Onan thing. I was always lead to believe that 14+ volts is considered over charging. Always learning new things Share this post Link to post Share on other sites
squonk 38,559 #6 Posted June 26, 2020 14.2-14.5 is a normal battery voltage with the engine running on pretty much any 12V system. Share this post Link to post Share on other sites
