17 volts on a 12 volt system?

Hello All,

I just got back from a rotation in Afghanistan to find my fridge on my Beneteau 400 Oceanis non-operational.

The fridge is a Frigoboat Frigamatic AH35.

While troubleshooting this afternoon I found the 12v system of my boat sending 17.2-17.4 volts to the Frig controller! The Frigomatic manual mentions that over 17 volts but under 22 and the controller won't allow the compressor to start.

I keep the boat on shore power when away and it was on shore power today during my troubleshooting.

I'm guessing that my charger/ inverter is the culprit? It is a digital unit and is showing 13.4 volts out with AC power in while charging.

Any ideas?

My plan is to take the boat off of shore power tomorrow and further investigate.

Thanks very much!
