So the bubbling / boiling sound was normal? The voltage it was showing on meter when charging was 14.xx volts.
Like I said the charger is suppose to stop when fully charged but I just got a little worried.
Now I'm worried about my on-board charger charging the batteries to much and ruining them while I'm connected to shore power (I plan on connecting to my house power the night before we leave camping to get my fridge cold and I wonder what will happen to may batteries if my 40amp old charger charges them to much or something.
Sure wish I kn knew more about this.
