another 12v waeco problem....

Quite possibly the wire size is too small, I get confused on wire sizes, but definately the bigger the better for sive of wire. Someone else will point you in the right direction re wire sizes.

Regards

Sounds like undersized wireing to me too, try plugging in to a direct 12v source using the plug supplied and see how it goes

Hi Chucky d,
Im not an expert but Id say the wiring is definetly to small. You need to be running 6mm auto cable as minimum. I run a 110 ltr Waeco when away on the back my 80 series cruiser using 6mm auto direct to the second battery. I've never had a problem.

i had the same problem, simple answer for me is to cut the cig plug off and put an anderson plug in it's place. doesn.t matter about the wire as much it is more about the contact in the join i found.

thread 81984 raised similar problem. I would say wiring too. If the wiring is too light could cause overheating and in worst case electrical fire.

You have 3 issues. 1.5mm Cu is far too small to run a 12 Volt fridge & building wire should never be installed in a car as it is far too ridgid & will snap from vibration over time. Run red/black 6mm multi strand auto wire direct from battery to fridge keeping as short as possible to avoid voltage drop. Replacing cig lighter type connectors with quality Anderson or Clipsal plugs will improve reliability.

Gday you should at least be runnig at least 6mm wire or go into any BCF and gets a raps kit it includes everything to run a waeco fridge

Waeco’s faults are more often than not due to bush electricians’ not understanding volt drop calculations and subsequently under sizing their cabling. Try and keep your volt drop to under 5% and you won’t have a problem. If you can’t do the calcs – reply with the current draw of your fridge and the length of cable and I will do the numbers.

Running to thin a wire will cause voltage drop as had been mentioned above. The reason this causes the Waeco to malfunction/error/turn off etc, is if there is a drop in voltage by the time it reaches the fridge, the fridge thinks that your battery is getting low, therefore shutting off before you have a flat battery. Just doing what it was programmed to do.

Im hereing this running to thin a cable to your fridge all the time. I run 4 mm cable at a 50 amp rating to my fridge, I have done so now for about 10 years, , running from a 80 litre weaco to now a 60 litre weaco, I have a circuit breaker up near the battery and got rid of the cig lighter plug ( they loose a lot of amps) .
upto today still no problems (touch wood)

Without doubt its due to the wiring being too thin compounded by the cigarette lighter socket. I played around with this problem and the best solution is to buy the wiring kit from Waeco. It has the right size wire plus correct fuse and most iimportantly the correct connector a merit plug.

just buy and fit yourself a Waeco Raps kit. Cost about $120. Google it or better still search EO here for it and you will see how it works as I have put links up for them plenty of times before. If you need to contact someone to buy 1 let me know and I will forward an EO Member details who supplies these and othe RV/4WD gear. Short of that just look at any camping, 4WD access shop or buy over the net. Very very simple to fit and you have everything you need in the kit, cheers....

G'day Chucky, bought a 60lt waeco fridge/freezer last year myself. Went over to W.A. and the same thing happened to mine. Had a hell of a time trying to sort out the prob. Stayed with the cable that came with the unit. Had to push the 12v plug into the Waeco until it was a tight fit. Found out the unit will not run correctly if your battery is down on voltage. Error messages and flashing starts for a number of reasons. Found most of these. Firstly back to the battery, run a multimeter on your battery and check voltage. If it is down below 11.5v, then disconnect the fridge and charge up your battery until back up to 13.7/13.8volts. Plug your fridge back in with the standard plug and hit the reset button and hold down for 5 seconds and release. The unit should be working okay now. Another thing that will cause the problem you are having is the unit does not like being operated on a lean and MUST HAVE adequate ventilation around the corner Air Vents, otherwise this problem will persist over and over. Do what I did Chucky, read the instructions that accompanied the unit 3 or 4 times over again. You will pick up bits you missed before and all of a sudden there will be the answer to your problems if what I have already told you doesn't work. Another thing, keep the fridge/freezer full at all times, even if you have to put plastic bottles of water in the unit as it helps maintain an even temperature and the fridge doesn't have to work as hard over a long period of time once it is cool/cold. Hope this helps mate. Cheers, Lyndon.

Thanks to all your replies, very grateful.
seems like everyone says the same thing... so makes me think i should change the the wire to 6mm and change over to anderson plugs.

thanks guys.
