Ok - so here's the deal. Going away this weekend and need to run the 60l Engel fridge off the battery supply in the ct(when we are camped, will run off the car when travelling). However the extension cord that I normally use has a damaged (as in totally stuffed, in the bin job) female socket. A replacement part is not available for this weekend. Would it be too dodgy to plug the cigarette (male) end of the Engel plug into a female in-line socket which has crocodile clips on the other end, and attach the crocodile clips to the bare ends of the extension cord wires? I can't think of any other way I'm going to run this Engel from the battery. The female/croc clip harness is a prefab one that you get from most car accessory
places and is rated 12amp load max. I don't want to start cutting up the Engel cord. Any ideas? Sigh - probably just have to take the esky and manage with that. I hate warm beer! Thanks for your input. Oz Doc.

So, if I understand you properly, you have a 12 volt extension cord/cable, the female end of which is stuffed. You plan to use the bared ends of this cord and the aligator clamps of the short adaptor cable.
The issue I see is that the aligator clamps aren't going to be able to get a good solid hold of the p!issy little cable ends of the extension cord. Also, even if you could get a good solid join, there is the issue of the 2 aligator clamps shorting out on each other.
You will suffer a certain amount of voltage drop over the length of the extension cable, even if it was in tact.
The other option is to cut off the aligator clamps and attach the longer extension cable to the short adaptor cable using either solder or a small terminal block (with screw connectors).
Is it not possible to take the battery to the camper or vice versa and then use the short cable adaptor with the aligator clamps directly on the battery with the Engel plugged in?
Good luck.....

Yep...Im with you Roachie.
Also bad connections cause heat! Ive had a fire in the back of the car once due to a bad earth!...small, but not pretty!
Cheers

Thanks Roachie, the extension cord is made of very heavy (thick - possibly 15 amp) wire. The Trojan is already in the front of the ct. I could drag the Engel to the front of the ct and use the alligator adaptor straight off the battery. The alligator clamps would probably make a better connection onto battery terminal than onto bare wires. However if I use the alligator clips straight onto the Trojan I bypass the fuse. Do you think this will be a problem?The wire on the alligator harness if very thin. Stamped on the female socket is "12 amp max load"-one would presume this also applied to the wire?

Lets look at the cost involved here.
2 cartons of beer : $80/90
1 extra esky and ice to keep it cold : $50/60
The cost to fix it $150/200
The cost of you're boggy repair job if it catches fire and KILLS some one in you're family,
well that's you're call.
Cheers Steve.

Now hang on a minute - I'm led to believe that if I let the pressure down on my "boggy" repair to 15 psi, that I won't get "bogged"! But you have hit the nail on the head. For the sake of a simple piece of 12 Volt equipment all the expensive gear (Engel/Trojan)goes to waste- right when I need it. When I do get the appropriate part - I will buy two of them! Ps - you overstated the cost to fix it - Arrid type two pin socket from 12 Volt
shop is only 19.95 plus p/h. Just no way in hell I can get one or anything similar here in
Karratha!
