That is very weird. Maybe I'm doing it wrong, but while the pumps are running, I stuck my test leads on positive and negative on the Pump +/- output on the interface. Clearly read 26v or more.

How is your pump life given your pumps are getting 12v to them. Any issues with your saloon freezer getting cold enough?

Hi all,

I have 2 pumps set up. A 12v and 24v, both work. My panel indicates that it is running 24v which is lit up.

I am metering 12v going into both pumps.

Just changed to make sure and they are both running OK.

I would like to help buy this fridge pump thingy is something else. I have a few spare pumps. Both 12v and 24v.

Very Best

Arno,

I just measured and got 26+ volts. 

The Frigoboat interface itself indicator shows 24v.

Hi Jamie,

I’m surprised you measure 24 volt. When I did the same I measured exactly half the voltage of the 24 volt system (about 13 volts when you are on shore power).
Did you measure under load? The whole Frigoboat system is made up in such a way it does not matter if your ships system is 12 or 24 volt. The compressor also reduces the actual supply voltage of the compressor motor to 12 volt irrespectively of the power-supply.

I recommend you check it once more. Maybe use a lightbulb to make up some load. If you still measure 24 Volt your switchbox may be broken, also explaining you extreme short lifespan of the pump.
