Temperature Gauges - Waeco Fridges

that sounds right to me, but where did you put them and where did the wiring go ? Camec sells a D cell battery operated fan, runs continuously for about 36 hours on 1 battery, purpose is to circulate the air inside the fridge - was made for finch type things but works really well in any static fridge set up such as engel and waeco. But the old computer fan sounds much better than churning through a D cells every couple of days.

I have them between the two baskets, one at the top the other about two thirds to the top.

The wire then just ducks out between the two hinges, I probably lose some sealing, but not a great deal!

Eskimo,
If you meant "thermometer" instead of "thermostat", I think I know the answer.
I use a Radio Shack inside/outside digital thermometer. The unit sits on my dash and I've added a few feet of cable to the remote sensor so it will reach the ARB fridge. I've used the suction cup which came with it to stick to the inside of the lid. I can now be confident the fridge has not tripped a fuse/plug come out etc, with the result that the beer is hot!!! I can handle most dilemmas when I'm out camping; but warm grog is one I can't put-up with...
A word of advice though.....there is a good deal of difference in the temperature between the top and bottom of the fridge. I leave mine on all the time and during the week there are only a couple of bottles of water in there. Although the temp gauge says the temp is about 4 to 5 degrees, mostly the water on the floor of the fridge is frozen. I usually keep 1 or 2 bottles in the small basket which is up at lid level and these don't freeze. Obviously, the computer fan idea would alleviate this issue.

ooops i meant thermometer
The bottles only freeze as the are in contact with floor I expect. I always run mine as a freezer and alternate plastic bottles to the small esky to keep my beer cold. If the beer does go hot for some unforeseen reason I always have some standby red.Wow, am I cute! The extra long legs are built-in prevention against ducks disease. Great looks and a real goer. Doesnt waddle along like some.

Darling the Jaycar goodie number is XC0116
Darling I have had them fitted in my shopping trolley car and the fourbie dear. Absolutely fabulous dear as I can make sure the battery is not going to die on me like the hubby sometimes does

Does the Jaycar one have a backlight which can be connected to truck's instrument panel lights? It would appear to run off the truck's 12 volt system too?
If so, this would be a better option than my Radio Shack one. Mine has a back light, but I have to know where the button is and it stays on for about 5 seconds. It is independant of the truck's electrics and uses one of those button-type watch batteries......I'd much prefer it if it could be connected to 12v.
Cheers,

the jaycar unit has a decent electronic blue light which comes on from the inbuilt light sensor unit. The clock part runs from two button watch type batteries and the temperature and voltage runs from the 12vDC
i leave mine permanently connected

You lucky buggers - Jaycar are flogging them on special this month (March) for $29.95 - 10 bucks off.
I measured the current draw off the 12v, most of which runs the blue backlight, and it only draws about 20mA; ie it can run for 50 hours before it uses 1AH off your battery, so a permanent connection to your 2nd battery is not out of the question. If in doubt, a switch to isolate it from the 12v would be the go. Go one further and put in a 3-position switch to select either battery, with "off" in the centre. An internal battery backup means that it can measure your temp even if the 12v is switched off.

Thanks for the great replys. I have just bought a Jaycar one and looks great. The problem I have found is that the temperature wont dispay (work?) unless it has 12v into it. This is a problem if you are running off mains power as the waeco transformer outputs 24v. I have got around it by finding an old computer printer 12v power pack and have wired the thermometer to it while it is running inside. Works a treat!

Works a treat - I spoke to soon! I have compared the digital temp gauge to a analogue gauge and at the lowest setting, 7 on the waeco the digital reads -9.5deg and the analogue -13.5deg, 4deg difference! At say -3deg and higher the units seem to read the same though. Waeco say that the FF90 will freeze to -15deg, so teh analogue appears right, and it has just been calibrated. Does anyone have this problem with theirs or did I get a dud?
