Hi everyone
I am wanting to know if anyone can tell me an easy (Non Technical) way to
test the Amps that my Engel is drawing using a Multimeter ???? I have done a couple of Google searches without much luck...
Hope someone can help me ????
Cheers Hilary ......

If you know how to switch the Multi Meter to the Amp
test. Do that and if you need to swap the leads do that.
Then if you have a Blade type fuze in the circuit that runs your Engel, pull out the fuze, insert your
test probes across where the fuze usually sits, then turn on the engel.
The multi meter should show the amps being used.

Hi Hilary,
First you need to switch your multimeter to the "10 Amps DC range". You will also need to shift the RED multimeter lead to the "10 AMPS" socket.
Then you must insert the multimeter probes "in series" with the fridge. To do this you must "open" the circuit and connect a multimeter lead to each side of the "break". To open the circuit you may need to lift ONE +ve wire from a terminal and place the multimeter leads ACROSS the break. Another way is to locate the fuse which feeds the fridge, remove it, and place the multimeter leads across the two contacts of the fuseholder.
AT NO TIME whilst the multimeter is in the 10 Amps mode should you connect its leads from 12v +ve and -ve or earth, or you will destruct the meter.
If your multimeter is a digital model there is no need to observe polarity (Which colour lead goes to which side) but if your meter is an Analogue model (with a scale and needle) then the polarity is important. If the needle moves downscale to below zero then simply reverse the leads for a reading.

Chopperdog (unknown name)
We run two fridges, Engel 40L and 21L, two lights and sometimes an inverter to give us 240V for charging kids toy batteries. The circuit used for this is a fused one that comes straight off the batteries to the rear of the car.
We have matching dual Allrounder batteries connected in parallel and we very rarely stop for more than two nights. Plenty of grunt in the batteries to start the 4.2 TD diesel motor. The batteries are around 10 months old.
And sometimes I may also fire up the ham radio (similar circuit) and chat for a bit.

Hilary,
if you are measuring the 12 volt side you will need a DC tester, your multimeter won't measure it.
Maybe easier to go to someone like battery world and ask them to
test it, or look at the manufactures specs.
Have a good one

Hell Rockape, I HOPE he is measuring the 12 volt fridge supply, not the 240v ac supply. That possibility did not occur to me!!!!!!
But most multimeters, both digital and analogue, read 10 Amps these days. Or am I missing a point here?

Chopper and Allen,
yep sorry about that, I just looked at my mulimeter and you can measure up to 10 amps DC.
Chopper you will just have to put the leads in the right spot and then measure the current in series, break the + wire and place the leads in between.

Chopperdog,
Rather than trying to actually measure the current draw you may find it easier to go
HERE on the Engel site where the current for each current model is shown. If yours is not a current model one of the same size shown will draw about the same.
Note that for each model there is both a range of current and a maximum current. The variable in the range is due to the fridge temperature setting and the ambient temperature. In other words, the load.

Just looked at the Engal site and checked the 32 lt chest freezer.
it states that it will hold 44 x 375 mil cans. That all right for an Alcholic but it does not say how many Deeeer it holds.
