As mentioned in a recent post, I think I may be able to get hold of
one of these second hand.
Is there an "official" way to wire them for running the fridge (CTL
350) whilst travelling?
I am thinking of running a plug out to the 12S socket on the back of
the car and back to a socket mouted inside the box and then fitting a
12S plug onto the fridge to take it from there.
Does anyone have any other suggestions?
yes, have the bloody common decency to acknowledge help given in your
previous posting, before trying to get other people to sort out yet another
problem for you. Alternatively, get off your lazy arse and find out how to
do things for yourself.
They consume about the same amount of power they pump when used
at normal refrigeration temperature differentials, which is
indeed significantly lower efficiency than a conventional fridge.
The standard 40mm square Peltier element takes about 4A at 12V,
and more at the car's charging voltage. I'm not familiar with
the particular fridge the OP mentioned, so I don't know what
size Peltier element it uses.

As usual, i'd not given enough info :=((
I think the where to connect which pin shouldn't take too much
figuring out. For the record, the CTL 350 is (was) made by camping
gas (well it's got their badge on anyway and is 3 way ie it runs on
gas leccy or 12(ish)V. Dunno what kind of element it used for the
12V, but it's rated at just short of 7A.
My real enquiry was to find out whether there was a standard way of
routing the cable into the Conway fridge box, standard place to mount
the socket etc.
Or indeed if this arrangement of "fixed extension lead" was the way to
Many overdue thanks, appologies and felicitations to those in
uk.rec.caravanning for thair many and various suggestions. On the
previous thread I initiated.
I think perhaps i'll stay where I belong in uk.diy in future mind or
perhaps uk.rec.motorcycling. The heat is a little too strong in

Replying to my own reply for the benefit of anyone who comes Googling.
I discovered from Tony Maris who hangs out in uk.rec.caravanning (and
runs a towbar fitting and trailer business in Derbyshire (Towbars &
Trailers (www.towitall.co.uk)) that the correct pins were 3 (earth)
and 6 (fridge). His site has some useful wireing diagrams which show
where these are. Mine of course had no voltage on pin 6 even when the
engine was running :=((
I had a dig about behind the carpet in the "boot" and discovered a
black box which I decided must be the split load relay and to cut a
long story short, eventualy worked out that there was a broken
connection inside the relay. I soldered this back on and now have the
necessary volts appearing on pin 6. (When ignition is on only)
The wire I soldered back looked a bit thin to be pulling 7A for the
fridge and potentially the current for charging a second battery as
well, but i'll see what happens before putting in thicker wire or
getting a new relay.
I think I read somewhere that some newer designs are voltage senseing
and don't switch the current through to the fridge & battery until
they see lots of volts comeing out of the alternator.
Either way, although Trailers & Towbars aren't strictly part of the
uk.d-i-y remit, I imagine lots of us have them, and I would like to
propose "Towbars & Trailers" for inclusion in the FAQ.

Tony also answers questions on the aforementioned newsgroup and will
discuss specific problems via email, but he only logs on during the
hours of darkness (well a little bit before in the summer months).
Thanks for the plug!!
Sorry I haven't got back to you yet about altering the chassis. I've been
reading a 244 page EC document about introduction of type approval on
commercial vehicles and trailers...... :-0 [yawn]
Hopefully tomorrow evening....

My "little man" has shifted the "box" back 11 inches, and very wierd
the trailer looks too.
Unfortunately, the second hand Conway box isn't available before this
weekend, so I just ordered a Storage Box from B&Q (which I hope will
do) only to discover after the web site had taken the order that it
won't be despatched till tomorrow (if you know the right route to take
and burrow through about 15 pages on their site, there is a notice to
say that after 2.00 PM it takes an extra day. Not impressed!
Still if it arrives early on Friday and I can build it during my lunch
