Hi all
This may get a little confusing but let me explain. I am after a 2 pin screw together socket set up for my Engel fridge. A mate of mine just came back from Birdsville and told me how he melted his cigarette socket for his fridge when it vibrated loose on the corrugated roads. I notice my Engel plug ( and probably most others) comes apart and reveals a two pin screw in type set up which presumably would defeat the vibration problem as it would not simply shake loose.

Where can you get such sockets. Repco, auto elecs where?

Boating supply shops like Bias Boating
have one that sounds right.

ARB installed my dual battery system
and they used these for a socket in the back.

I got some extras to make an extension lead

Correct they are chrome brass, the female plug base is surface mount & male threaded, & the male plug has a female threaded collar. Almost any chandlery will have them.

If you are after the mating one for an Engel fridge, you can get them from TJM, ARB, Boots Camping etc. They are not cheap though, around $ 35.00 from memory. Part No. is ' S-PAN ' this is for the socket attached to about 250mm of cable and an inline fuse. They also do a long cable version and one with a switch, but these are even more expensive.

Stillthinkinaboutit is correct.... It is a Engel part . The type from the marine shops are different again but are two pole also. These sometimes come with a screw cap....
Think about a probe also from Engel for the tempreture reading that can be extended to the dash... This way if the plug did fall out you would see the rise in tempreture....

I think the ones you are talking about are the 12v marine plug and socket made by Hella and around $30.00. I have been using these on my Engles for a few years now but in hindsite would have used the two pin 12v plug similar to the household 240v type(cant remember their correct name) they can be bought from any electrical supplier and are half the price. I have had a few problems with the marine type with the pins wearing and loosing contact You wouldn`t think that would happen as they are a good quality plug but I have had to build two of the prongs up with solder to keep them contacting.

I use the hella ones. http://www.hella.com.au/cgi-bin/catalogue.pl?flcmd=prodver&flrecid=327

I've got the 4951 and 4918. The advantage of these over the others is that they are dual purpose meaning you can still use it as cigarette lighter socket. If you are looking for the other type I'm pretty sure they are called merit plugs.

The most reliable plug/socket arrangement for a car fridge is to use a "polarised extra low voltage" plug top and surface mount socket. They are available at any electrical wholesaler. They won't vibrate out and will easily handle the current draw of your fridge.

He he

Nah I find this all very helpfull. You would think as an electrical contractor I would have thought to look up a Clipsal catalogue first before I botherred everybody here though wouldnt you.

But I am grateful for everybodys input, still thinking about which way to go as there is no urgency yet.

I use them on all my accesories and also Trailblaza fridge came fitted with them

Yeah, we've been using this type of socket for many years now and never had a problem. 12V lights in the camper also use the same.

my engel is fairly old and when I unscrew the plug the front bit comes off revealing 2 flat pins. All I use is 2 automotive lugs that slide right on to the pins. cost couple bucks.

Wizzer & others using the push on lugs that slide on to the 2 flat pins.
Warning I did the same and when I slid my Engel back the cable got caught and pulled the plugs off. When I reconnected them I accidently reversed the polarity and have ZAPPED the fridge. The fuse is in the cig lighter end and therefore I had no protection. I have heavy duty cables that run from the aux battery which only has a high amp circiut breaker. Fridge is now dead & I'm looking for a doctor. I'd advocate using a plug that does not allow you to connect in reverse.Cheers

have you checked on the moter compartment cover for a little button that is marked reverse polarity reset (from memory) this is desined to protect the fridge from reverse polarity the fridge may not be dead.
I know my old engle had this button on it as the engle power lead didnot have a locating pin on it when you unscrewed the cigi lighter end so it was easy to reverse the polarity may have rectified this on newer modles.

Bruce I can not find any reset button on my engel. It is about 4 years old. Where exactly is your reset button as I might have to have another good look?
I did not want to cut into the original 12v lead and put an in-line fuse in (I wanted to keep it all original so I could put the cig lighter plug back on if I had to use it in another vehicle). I wish I had put in an inline fuse now. I believe they should have the fuse right at the frige itself so people can modify the leads and remove the Cig lighter plug without risk damaging unit. Cheers

Save the hassle - buy the correct lead made by Engel, with the inline fuse. It is about $30. You've got a $1200 fridge, silly to be cheap on the one thing that will keep it going. They are easy to obtain.

And yes, it doesn't vibrate loose, as it is all locked together.

Don't use cigarette plugs for vital connenctions.

You know then Engel genuine socket is expensive when ARB can sell one which is cheaper!. And we all know how much markup goes into their products.....

Cheers,
Glenn.
