Engel 60 Combi

Hi Macca
I bought one just before xmas and it's first trip was to the Flinders Ranges - Innaminca - Birdsville and areas there abouts during the month of January.
Temps into the 50's. Bloody hot.

I have not checked the actual amps drawn but during this trip the unit was run as designed fridge/freezer combination and I must say worked real good the ice cream stayed frozen during these high temps and the coke was icy cold in the fridge half.

Both sides of the unit were full to the top almost all the time so it was running constantly to keep things frozen.
The longest time I had the unit running of the second battery without starting the car to charge anything was about 16 hours.
Battery voltage dropped from 12.6 to about 11.9 volts by my old multi meter.
Your next question will be what is the size of my duel battery, The answer is bugger it if I know of the top of my head and it's now to late to go outside and look so I will have to look tommorrow and let you know.

If someone can enlighten a basic user of the multi meter like me as to how I can measure amps I will check it next time I use it (in a couple of weeks) and let you know.

Regards
John

To measure amps, you first need to make sure the multi can cope with what is being drawn, so if the fridge maxes out at 4.5a and is on a dedicated circuit (without a hf or anything else connected down stream) and the multimeter can measure 5 amps or more, you turn the knob to amps and take out the inline fuse you have installed, and put one lead in each side of the fuse holder and get someone to turn the fridge on. This should be ok on a circuit that is not experiancing fuses blowing at the time you decide to test it.
Keep in mind that the fridge doesnt run 100% of the time, so if it uses 5 amps for 30 minutes of running per hour, the battery will be depleted by 2.5 amp/hours.
Also, if your aux is 12.6v full ,it is not getting enough charge or one of your batteries is on its way out. did you measure the voltage with the motor running at all? 12.6 is a little low for a full aux, it should be 12.7 minimum, and with motor running 13.6 minimum up to 14.6 max.
