This was one of those jobs that I umm'd and ahh'd over for a good month or so wondering whether this was a job I could undertake myself or not. Not being the most savvy electrician around and car electrics usually causing me a good few head scratches before understanding it (sort of), I really wasn't feeling that confident that I would be able to pull this off without completely fusing the entire car and doing a whole load more damage than good.
As ever, Dave was on hand (text) to provide opinion and expertise... ... this is how I kinda figured out what went where.
Easy right? All I have to do know is replace the bit of paper with the actual van and away we go. To be fair, I bought the leisure battery and split charge system from TravelVolts (www.travelvolts.co.uk) and the instructions that came with it were excellent - Martin was even answering a few questions via email despite being on a 2 week shutdown - Thanks Martin.
- Lower dashboard panels off again - with flashbacks to doing the electric windows
- Under the bonnet, take the windscreen wipers off,
- Remove the plastic trim underneath the wipers that keeps everything looking neat.
- Remove two torx screws and then lift out the metal plenum out from behind the battery.
- Now poke the very thick red cable through the grommet in the bulkhead and feed it down behind the gear lever column.
The most popular location for the leisure battery seems to be under the drivers seat. There's a channel in the bodywork from the base of the gear lever column to underneath the seats for wiring already so just need to reach under the cab matting and feed it through. That bit was actually a lot easier than I had expected, even with having to remove the drivers seat Don't be too hasty here though as there's a very small thin wire connected to the seat that you could easily rip out if you don't know it's there - disconnect it first by reaching under the seat. The other trick here for me was removing the drivers side step to get better access under the cab mat.
It does all get a bit snug under there but it does all fit. I installed a 6 way fuse box at the front of the battery that can be accessed from the front of the drivers seat. Just a simple eBay job but it does have little LED's indicators for each fuse which is a handy feature.
I'll need to tidy up the cabling at some point but it's in.
Having got this far, the most nervous bit was actually connecting all of this to the main battery. Everything crossed again as I really could do without fusing the whole van. Installed the final fuse into the carrier just by the main battery and then connected it all up.
At this point, I assume it's working. The van starts OK and there isn't any blown fuses that I can see. All seems to be as it was intended.
Actually feeling quite proud of myself.
No time to waste, now to connect stuff to it. To begin with, I'll start with the USB sockets for the rear passengers and the 12v socket at the tailgate. At least then things can be charged at campsites without fear of draining the main battery and not being able to start the van.
This is where I'd like to think I'd been a little bit smart. I'd already run all the wiring for the sockets into the roof and coiled up some wire up there ready for doing this job when I was doing the insulation and carpeting. So for this job, the only panels that needed removing were the B-pillar covers and a few studs from the roof to retrieve the wires.
Connected the two USB sockets to one fuse. The sockets are positioned in the end of the bed frame on either side so should be nice and handy for the rear passengers (mainly the boys).
That seems to be working fine.
12v socket connected to it's own fuse and actually has an in-line fuse too as part of the kit I bought on eBay. That's working too. This will come in very handy for blowing up airbeds when we all go away and take the tent too.
Actually feeling very proud of myself at this point. Time to tidy up and have a brew.
