My split charge system

As the weathers changing for the best I decided to install a split charge system to Vinnie mainly for running a coolbox/fridge whilst camping but to also charge phones and other bits too. After reading many other threads on here and getting some good advice regarding different methods (Iguana, Sailorboi & Nic Symonds) I decided I was going to use the T-max Split Charge System.

I'm not keen on adding extra bits to the cab of the D3 where they will be on view and pondered on a few locations to mount the T-max controller, eventually I decided for me the best location would be the upper glove box! So with this in mind I started working my way back from there towards the spare battery box under the bonnet. I drilled a small hole in the corner of the upper glove box and threaded the wires through, I then went on to route them behind the glove boxes.

Then from the drivers side footwell I pushed a length of solder through to the passenger footwell to use as a pull through, taped the wires to it then pulled them back through.

From here I ran them under the carpet and over to the grommet leading to the engine bay. As you can see I pushed a screwdriver through the grommet and nearly caused myself all sorts of issues Shocked

I then replaced the screwdriver with the solder and pulled them through into the engine bay

The red wire will be too short so I will extend this to reach the main battery. This is how I will use the controller when needed

And when not in use I will just leave it tucked away like so

I next moved my attention to building the rear panel that will house the 12v sockets and usb sockets. I pretty much copied another forum members (Nic Symons) design for this. Firstly I cut a piece of ply to fit inside the back of the rear drivers side cubby panel

Click image to enlarge



Then I marked out where I wanted all the items to go with a pencil and tape measure and started cutting/drilling. After I had marked out the rectangle hole for the volt gauge I then removed the ply and cut a bigger rectangle out of that too


Click image to enlarge



Until I had this


Click image to enlarge



On the back I fitted a fuse box screwed to the ply and set about wiring it all up.The blue wire and smaller wires going to the volt gauge are only temporary as I didn't have the right size cable to finish them


Click image to enlarge



Click image to enlarge



I then hooked it up to a spare battery to test it all worked.........which it did Thumbs Up


Click image to enlarge



Click image to enlarge



Click image to enlarge



Once I was happy it was all working I put the panel back into its location to see how it looked


Click image to enlarge



Next step is to source some small black screws to fit the socket surrounds on properly and then to get a yellow top Optima battery ordered as well as a battery clamp to fit the spare tray. Once that is in place I will measure up the length of cable needed from the aux battery to the rear and get my local auto electrical shop to make it up for me ready to be threaded onto it's final position.

Looking good Thumbs Up

IVe just started something similar myself. Just need the cable to go from aux battery to rear cubby. I'm sure someone will know how long it needs to be.

Iceman, thats a really really lucky call there with that wiring.
You've gone through the wrong grommet, there is a much better one to the right of the Brake Booster tucked away into the bulkhead. You can put a screwdriver through that one with no risk to the wires.
The preferred route is the one to the right as most vehicles are Auto's and it is used only for the Manual clutch cable, so plenty big enough for the cables that are normally needed.

I like the 'box' being tucked away in the glove box. :thumbsup:

Sorry for the late reply! The plyboard was 1/2" thick and all the other bits were off eBay.

I was slightly worried to say the least that i'd done some serious damage!

I'm guessing your referring to this grommet?


Click image to enlarge



If so it looks a million times easier to get at Banging Head Thanks for that, i'll pull the cables out and re route them through that grommet I think, and also my new positive cable for the rear will go through there too!

The glovebox was the only place I was happy with putting the controller.........so thats where it went! :thumbsup:

No worries, I asked at a timber merchants for an off cut of ply so it didn't cost me anything Thumbs Up

A bit more progress today......

After Bodsy telling me of the better grommet to use I pulled the cables back into the drivers footwell and fed them back into the engine bay via the new improved grommet


Click image to enlarge



Click image to enlarge



I removed the siren for better access as I don't use it anyway and mounted an inline fuse holder to the inner wing behind it. I then went on to route the positive cable from the holder to the rear cubby, it still needs tidying up in the engine bay yet. The cable that was recommended was 16mm2, 110 amp.

I ran it behind the foam near the pedals and down in the corner where I fed it all the way to the rear in a duct that already houses cables

I decided to use one of the already threaded holes for my earth so I gave it a good clean up and attached my negative lead to it

I've also taken delivery of this bad boy, so hopefully not long now and it'll all be up and running Cool

Thumbs Up Awesome write up!

You really went to town on removing panels. I went the same route to get power to my roof lights, but didn't want to take all those rear panels off... Ended up fishing the wires thru with a fibreglass rod, much like you did with the solder! Mr. Green

Excellent Iceman,

I am following this with real interest. Thumbs Up

Any tips to remove the rear qtr plastic trimm?

Already have the split charge system in, just need to get the feed to the rear of the car now.

I also planned to use the earth that is already there inside behind the rear lights in the back corner. Any reason you didn't use that?

cheers.
