UPDATE --- Converter/charger issue?

I'm camping in a remote campground in the Canadian Rockies. I have an Iota45 with the smart charge dongle connected that is supposed to turn it into a 4 stage smart charger. I have a small voltage gauge hard wired in to the RV and use an inverter generator for charging during the allowed hours of 5 to 7pm.

Lately what has been happening is when we arrive at a campground with fully charged dual 6v golf cart batteries, the built in charger will not charge the batteries later that day after some use on the batteries, even though the resting voltage is 12.4v or so. (It used to charge from this level). Happened at the last campground too after unhooking the 7 pin.

It's like the converter/charger doesn't recognize the drop in voltage from use. When we unhitch we are usually at 12.8v now down to 12.2v and it usually goes to 14+ v when I fire the generator up. Now it's just been sitting at 12.2v and I can tell by the sound of the generator on smart throttle, it has no load.
  • The dongle I refer to is the IQ4 that plugs in with a cord similar to a landline phone.

    Kirkland 6v golf cart, I just checked and added about 2oz of distilled water to each cell. Plates were all still covered in electrolyte before adding water. Now at 12.3v resting voltage and no charging when I fire up the generator.
  • what kind of batteries and have you checked each cell electrolyte level?
  • Batteries are 1 season old and have little use and are well maintained.
  • Before the smart charge dongle was added it used to charge at 13.2v give or take. Now it goes to 14.6v at peak. I've tried unplugging the smart dongle - no difference.
  • I've done some basic trouble shooting. I have cycled the breaker for the converter charger and did notice a high pitched whining noise from the iota when the generator was running, but no charging action. The converter isn't hot no strange smells. The voltage gauge is accurate as I have double checked that by plugging a secondary one into the 12v barrel connection.

    Any ideas? Keep in mind I can only check during generator hours (5-7pm) and I only have basic tools and no multimeter.
