Hi All,
My fridge is starting to annoy me! I run it the garage on my power supply..runs great,put into my truck and it throws an error light..put the multimetre to the back plug plenty of power to run it..no heat..so wire is not to thin..checked the battery with a hydrometre reads OK..checked earths all OK..I'm going to run a battery cable all the way back to the fridge and use 50 amp anderson plugs to supply power..if this does'nt work...I think I have covered all bases?????

This seems awfully strange. Are you running ANY other accessories? I am wondering if something else is running, and maybe pulsing, giving you an error light. Normally the light would only come on if there is not enough voltage. Sometimes, I have seen this, and it can be what is termed a dry joint inside of the female plug socket.

Try this....

Connect your power pack to the battery terminals, with the battery disconnected of course, and quickly see if it works or not. Process of elimination. If it doesn't, then you've got a voltage drop problem inline somewhere.

Its a dedicated power sourse,but will check it as I replace the wiring with heavier cable...not sugesting the wire is to thin but just want to make double shore its not nice going bush and your second guesing your food because of fridge...er.. your write somethings being overlooked somewhere.Thanks for your input.

goodday jd
what sort of plug are you running
in the back of the patrol i have my fridge fed by a 6mm twin wire (red & black inside a sheath)it has a fuse at the battery end and a T plug at the fridge end cut the manufacturers plug off
the T plug is a 32v rated and i have more trouble unpluging due to very tight i have pulled the wires out
i keep finding the cigarette lighter type plugs are just a pita

Hi Folks,
I use a cigarete type of conector and socket..but it connects quite firm and has been good for about 2 years now??This the confusing part and everything seems to be good.Thanks for your input.

Cigi plug sockets are notorious for letting you down. What about a Hella type plug? Much more positive connection.
Also, despite you getting good voltage reading on a multi meter at the plug end where it goes into the fridge, if there is a bad connection or a partially broken wire (eg: the internal cable near the plug could be mostly broken from fatigue.....you wouldn't be able to see it and it would still conduct 13 volts, but not enough grunt for the fridge).....

What about trying to power-up a portable compressor (like ARB etc) using this power lead? They draw about 30+ amps and that would "prove" the cabling is adequate. To do it you'd need to make up a "joiner" section of cable so you could poke the metal ends into the female end of the fridge cable......just a thought. If you do this, you'd probably need to actually have the compressor under load, by attempting to inflate a tyre.

Good luck

Hi JD

Suggest you try two things.

1. If you have a blade fuse it may have gone high resistance due to metal incompatibility. This has happened a number of times to me.

2. Make sure the earth on the battery and other connections are correct and not insulated by body paint. This also has embarrassed me.

Three
do NOT use cigarette lighter sockets. Bad Bad Bad

we had same sort of problem - found out it that it was the little switch that we could put it on to say how much drainage we wanted from the battery - sorry for the non-intelligent terms! - forgot to change the switch when we put the deap cycle battery in....now she's working good....

G,day JD
As I said to you at the Show & Shine Sunday, that I sometimes have the same problem. I shut the fridge down for a few mins. and re start it and the problem dissapears for some time, but i will be interested to see what comes of this thread. For those that did not hear our coveration Sunday. I have a 60lr Waeco and i have installed a curcuit breaker with 2 merit plugs and 1 Cig lighter plug, it also has a volt meter built in and all showes well there and getting 12-13volts unloaded and 12.5 loaded (with compressor on) but that error light still sometimes comes on????.

JD,

Are you running the earth through the vehicle body, or do you use 2 core cable, as mentioned in one of the other replies? Seems there can be plenty of problems with vehicle earth return.

Merit and Arrid are 2 types of reliable plugs, as well as others made by Hella, and Narva.

Hooroo...

I suspect that you are getting a voltage drop under load at the frig.
The only way to check it is to use a good quality multimeter connected across the frig side of the power plug, usually you can pull the cover off the plug and just watch it as the frig first starts, you will probably find that it dips momentarily.
A normal 12v voltmeter (as fitted in vehicles) won't pick it up usually.

G'day Peter
my volt meter drops for a split second, on compressor start up sometimes. Maybe that is enough to trip an error light in the fridge. Now all we have to do is solve that problem??? Do you think JD has the solution useing a battery cable, or is that overkill???

as others have said definitely a 12v problem by the sounds of it

dirty wiring connections, poor joints (which heat up creating high resistance joint under load) or cabling is or are the probable reasons
this could be vehicle 12v or unit 12v wiring....connect straight onto battery to check?..this eliminates all vehicle connections that might otherwise be suspect.....if problem still happens then most likely 12v wiring problem in fridge...

I have the same problem with my Waeco 50 L The problem is with the plug in to the side of the fridge. If you wiggle it the error light will come on. I have a replacement plug, that I can take apart, so I squeeze the terminals and put it back toether and it is ok for a few months. I have heard of this problem a number of time on this Forum now.

Well you got me thinking but at the show'n'Shine the truck was parked and there was no movement at all,I pulled the plug out and check power to the plug with On Patrol while we were discusing it,so it was a new conection so to speak..but will have a look at the plug conection while i'm going,Thanks for your input.

Chuck it and buy a real good esky.
We survived really well on our 3 1/2 month camping holiday just with an esky and during that time we only had to buy 3 bags of ice. We just lined the top after filling with a good thick newspaper. Every time we were going to go bush for 5-6 days we would ask store managers, caravan park managers even butchers if we could freeze our bottles of salted water and our goods before we took off bush. Never had a knock back. Drysdale River Station was the only place we paid for the service and it was only a couple of dollars to freeze bottles and we bought meat which was already frozen. Then if we still had a day or two swinging we got stuck into the Tin Muck or pasta and jars of sauce. No problems. Only caught enough fish to eat on the day etc.
Everyone is different.

Hi Greiglin,
If you new me you would never say throw it away,when I cant fix something..to the piont of frustration I usually just park it in the corner of the shed until I drag it out and most times fix the dam thing with a fresh outlook on it..for instance..a 4 " grinder of mine which give up the the ghost about a year ago..I've been doing a garage cleanup,..and came across it again was about to throw it out a thought to my self I'll have a quick look at it..took me about 25 min good as new now,it had a partial cooling fan colaspse which I broke out the fan part that welded itself to the shroud cleaned up sandpaper...bla ..bla ..figgered I was on about 50 dollars an hr for that repair...that why it good to put these things to the forum because the smallest of comment somtimes puts you on track to fixing it..Hope I havent bored you..Thanks for your input.

Greiglin, interesting post.
Have been tossing up weather to buy waco, engle or simaliar.
From what i have heard, those eskies are really good. Can you tell me what sort of esky it is, how big is it and where you live. I live in townsville (Very hot) Did you use dry ice or ordinary ice? Also what was the esky used for , beer? food? or both? As i have 4 children and esky would probobly be used for all of the above, do you think the esky would stand a chance as apposed to a waco or engle?
Cheers

Hi JD
Havent read all of the threads but if its a Waeco then check the socket on the fridge and clean the prongs(?) where the cord plugs into it. They get very dirty and corrosive. Been caught a few times with it and now its a normal part of my maintenance routine. The tiniest speck of dirt will interrupt the 12V supply.

Maybe a squirt of WD40 or similar on the prongs/plug might be a good idea. I have to do that on my trailer plug from time to time when lights don't work etc.

Hi, I had a similar problem, would run on the 240v supply but sometimes not on 12v. Problem got worse until it would not run at all. Contacted fridge manufacturer and they knew the problem instantly (over the phone). Their explanation was; Turned out that some years ago (3,4 or 5 years now, have had fridge for long time)," Danfos had a bad batch of motors that had a wiring short problem in the windings. The bad batch could not be identified by serial or batch numbers. Just had to wait and see which went bad." My fridge was fixed free of charge by replacing the motor, electrics and dryer. Electrics and dryer because the latest and greatest motor was supplied and installed.

Not bad service really as I bought the fridge second hand from a private sale. I delivered the fridge to the manufacturer (I was heading that way) and they shipped it back to me free of charge.

So a secondhand fridge was made new again!

Not saying that this is your problem but just maybe...

Good luck

Hi TonyJ,
Thanks for your input,mine runs spot on from my 6 amp 12 volt power supply..240 step down ofcourse..I'm going to change to heavier wires and anderson plugs..once I do this of course and it still happens..I suppose it only leaves the battery...anyway I'll will sort it out.

JD, just a note on cabling. Earlier in this thread it was mentioned that someone was using 6mm red and black cables incorporated in a black sheath. This is automotive cabling and the actual 6mm size is more relevant to what size hole the cable will fit through. Typically this cable will actially be around 4mm squared (the correct measurement of the conductors actual cross sectional area - used for 240 volt mains cabling measurements etc)
With my fridge in the back of the car I use an automotive cable where each conductor is close to 16mm squared. Both positive and negative are run back to the battery via a DC circuit breaker. I ran the cables through the chassis rails which simplified the installation.

Hi Tony,
Thanks for taking time to advise me on cableing,i've been contemplating running the cable thru the chassis rail since the weekend when I was talking to fellow at the show'n'shine he was full of monkey cunning..and sugested I do just that..which now I think I will after you have confirmed this is the way to go..with the size of the cable I was pretty much onto it..I checked with my metre today and the fridge seems to pull 3 amps while the compressor is running..if i'm reading it write the voltage drops is really insignificant.Should have it sorted shortly.THanks for your input,Much appreciated.

For the 5 amp startup surge, you need really high contact pressure. The pressure for the centre Cig Lighter contact is provided only by the friction on the outside of the Cig Lighter - UNLESS you have the Cig Lighter Socket that has the retaining springs.

These springs are visible inside this socket here.
http://i23.photobucket.com/albums/b356/MikeAus/Auto/PICT2566DCConnectors100k.jpg

If your socket in the Power Supply has these springs but the one in the car doesn't, it could explain your problems.

SOLUTION - DON'T use Cig Lighter Sockets.

Hi Mike DID,
Its not really a cigarete lighter plug just similier..its been good for around 2 years..and it fits nice and tight..the ones in my power supply are hard contact type which i push on independently of each other..Yes I understand what your saying about not useing cig lighters plugs but if you seen and felt the connection and how secure it feels you would no why I have used it..anyway its all being changed to anderson plugs and heavy duty cableing...if it did'nt last this long it would not be confusing Mike, Thanks for your input.

Is there any way you can get rid of the plug socket on the fridge? If you're going to the trouble of running heavy cable to the rear of the vehicle using Anderson plugs, it would be a shame to still have to rely on the small metal pins in the plug on the fridge. What about taking the back off the fridge and if possible, attaching the new, heavy wires, directly to whatever junction set-up is inside that the plug leads to? I would envisage having these 2 heavy cables coming out of the fridge and maybe having a couple of feet of this cable exposed, with an Anderson plug on the end of that. It would mean the fridge was only able to be used in YOUR vehicle (or someone elses if they too have Anderson plug socket of course).
