What size fuse

Hi there Sand Man, no its not, only one batt and only a 450cca at that. I am thinking of getting the same battery as in the hilux which was a 760 cca and was great when were down the high country prior to xmas running the fridge at -16 as a freezer never had a starting issue although it was started and driven everyday. I was just looking under the bonnett and aint much room under there for a dual. It must be able to be done as I have heard other people say they have dual but I have never seen it for myself. Regards Steve M

OK Stephen,

Just make sure the low voltage cutout on the Waeco is set so that your one and only battery is well and truly protected from too much drain.

The Waeco experts will tell you what setting to use.
I'm an Engel user myself.

Strongly recommend you look at a dual battery system at your ealiest opportunity, or alternatively, spend a similar amount on a portable battery system that can be charged from the alternator while driving, the fridge being run from this portable battery whenever possible.

Thanks Sand Man Derek has just posted a pic of his on here now, so will be taking a good look at the set up. Regards Steve M

Hi there Howie, no it is a standard cigi socket but the wiring is very thick, roughly the size of a power lead eg toaster, kettle. I havnt looked at the back of the cigi connection. I have no idea how he would get a wire that thick to be connected to it. Am going to have a look tomorrow in daylight.

ok.
remember cables can be all insulation and little copper, its the size of the cross-section of the copper that matters.
the length from batt to fridge is important in calculating size/voltage drop.
a good cable supplier should be able to work it out for you.
i would leave the cigi for general use and run a new cable specifically for the fridge.

Dual Battery in V6 3400L 12 inch N70

Hi there Derek, ok Dual batts NO, wire size, just had a look and it has written on it HIGH DEFINITION SPEAKER WIRE, but more like that monster cable, there is two strands of it (joined together) like a positive and neutral, One end is connected to the body next to under bonnet fuse box the other to the fuse box. It runs in with all the other wires running into the base of the fuse box. Now at the other end just took side compartment lid off where the jack and tools go on passengers side in the rear cargo area and the wires are just sitting there so are not connected to the lighter at all. The lighter has the original wiring connected to it. The light on the dash that the wiring goes to and from I just checked and only works when ignition is on. Regards Steve M

What are your plans ? Have you got a fridge and what size and type ? It may pay you to reconfigure the wiring for the time being until you fit a 2nd battery or Power Pack. If you have a 3 way fridge then the current wiring is fine but if you have a compressor fridge you will need to by pass the relay and ignition switch. Fit a socket and low voltage protector to the wire at the back. (Also replace the battery with a big one, MRV70 105 a/h with 760 cca)

Hi Derek, yes have a 50L waeco. Can I just use whats there for now eg, get rid of relay, run straight from battery with the current 30amp fuse bypass the switch inside and run direct to the rear and fit a cigi type socket next to the factory one thats there already like the one in your pic. Would this wire fit in the back of the one like in your pic or would it be too fat. Also should I get a lower amperage fuse or is that not an issue as the fridge has one anyway ? Regards Steve M

Hi Steve

First remember that your battery is very small and the fridge will drain it very fast. I don't know what size the wiring is but if you can fit a lug on it to suit the cable and socket then great. (Make sure it is at least 6mm2). Leave the fuse at 30 amps (Less voltage drop) and the fuse in the Waeco plug will protect the fridge. The Waeco has low voltage protection so you should be ok. Phone me if you need to know how to by-pass the relay.

Thanks Derek, appreciated will let you know how I go. Regards Steve M

No apologies needed there Shaker, no problem. Hope he gets back to you. Regards Steve M

Hi Shaker

I leave on Tuesday the 27th of March to inspect our new fridges and will be back on the 10th of April. Call me and I will send one out today.

Regards

Derek.

Hi Shaker,

Thanks for the call. The volt meter is in the post.



Regards

Derek.

Derek, I can't thank you enough.
I couldn't find one with the expanded scale anywhere.
