G'day all,
Any advise on this matter would be greatly received .........
I am about to fit two pairs of 105A/h 6V batteries to my campertrailer which will give me two independant 12V supplies to run my Waeco fridge for extended periods. My question is .......
if I fit externaly, two 12V panel mounted lighted sockets on short heavy guage cables, do you think this would work and be suffient for my application. It has been suggested that I change the lighter plug on the Waeco to something more substancial which would also mean changing the sockets. I am hesitant to do this as I also like the convenience of being able to plug the existing standard set-up into the rear socket of the vehicle. Your thoughts ?

The general consensus is that the cigarette lighter sockets are woefully inadequate for running a fridge and will cause significant voltage drops as well as potentially overheating.

Dump them and fit proper sockets (Hella do a good one) to the camper trailer.

While you are at it, fit a similar socket (or two) to the back of your 4WD and run heavy gauge cable directly from the battery to power them.

Thank you for responce. I have taken your advice, in part, and ordered plugs and sockets from Hella. ( socket part no. 4918 & lighter/din plug part no. 4952 )
The lighter/din plug is a new item from Hella which allows it to be used with it's specific matching socket or with a standard lighter socket. I think this may be the best sollution to my situation as it will still allow me to use the existing socket in my 4WD. I understand what you are saying about up-grading the 4 WD socket and wiring but up untill now it has'nt caused a problem with the opperation of the Waeco.
I thank you again for your advice.

Don't forget, if you connect anything to your battery direct, it needs to be fused.
The last thing you want, is your nice new heavy guage wiring rubbing metal and causing a fire. Use a suitable fuse according to the guage of the wire. Formula used is 3A per 0.5mm of wire.
I concur with the cigarette lighter outlets, they don't provide an adequate connection. The Hella plugs are very good and capable of high amp continuous running.

Cheers Mate.

The Hella Din sockets and plugs at http://www.hella.com.au/ are rated 8Amp @ 12V or 4Amp @ 24V.
The beauty of this design is that once pluged in - the connection is positive and not likely to accidentally become disconnected like the cigarette type sockets can.

The plug on the Waeco is fine, it should have a red bit on it which when you pull it off it will plug into the Hella style socket which as said before is far better than a lighter socket.The cable and plug that comes with the Waeco will do the job no worries, people only have trouble when they plug this into a normal cigarette lighter type socket, get bad connection and also too much voltage drop.

Thanks guys for all your advice. I have taken it all in and will act on it accordingly.
Interesting info on the Waeco plug. I have been using it for a while in the rear of the 4WD, with no problems, but did'nt notice that the plug was duel designed to fit a Hella socket and standard lighter. Good to know.
