Hello,

Had a slight problem, while plug into the 120 volt system at the campground, one of my dual batteries exploded making quite a mess. After cleanup I measured the voltage going into the dual batteries and it was 16 Volts. I am assuming it should be around 14 volts. Is this what caused one of my batteries to explode? Or was it just low on water? Obviously there is a A/C to D/C converter and I am assuming a Voltage Regulator. Anyone know what the voltage should be and how to troubleshoot? My Barth is a 1976 with Chevy 454.

Can't speak for yours, but the one I took out of my 84 did not put more than 12 volts into the DC system. It was a converter, not a charger. Most older ones were like that. What converter do you have? Got any literature on it? 16 volts is commonly used as an equalizing charge, and does not usually explode batteries. I wonder if a spark ignited some hydrogen.
It's a good thing you weren't nearby. Safety goggles are neat for battery work.
