Bought 4 new group 27’s for our two main banks and a pronautic 1240p yesterday. Hooked it all up and every thing seemed fine but when I fired the charger up and set it to preset 2 flooded the DC voltage went up to 15.1v. The preset is 14.8v max
I had to run, so I shut it all down and didn’t play with it too much but I’m concerned with that voltage. Without the charger on I see about 12.4v using a multimeter right on the posts.
I’ve emailed pronautic to see if it’s a bad charger, but what do you guys think? I’m going to go back today after they sat for a night and try it again.
side note, the previous owner had the port bank positive lead on the batteries with the starboard negative lead (and vice versa on the other side). I looked at the diagram and I don’t think that would matter because both engines are tied together with ground and they all share a common bus bar but it was a little alarming to find that way
