How to wire a transit conversion

[JD01]

Hi folks,

Hoping to get some eyes over my wiring diagram for my transit minibus conversion. It's a 2015 Transit and i'm about to start running some cables. Electrics are new to me and i've spent a fair while trying to learn over the past few months. I would really appreciate it if someone with more knowledge than me could take a quick look at the diagram.

The plan is to have a 220ah AGM battery under the passenger seat (the starter batteries are under the drivers seat) with the plan to run cables to the rear wheel arch where the electrical cupboard will be.


Any advice would be much appreciated!

Why is the ctek wired to the ignition?

If it's an automatic charger just leave it on all the time powered by the solar panel.

I would also advise installing a power inverter, so you don't have to rely on hook-up power for your 230v,

I'd add a bond (earth/negative) close to the leisure battery aswell.

It wires to the ignition so it only charges when the engine is running. The solar connection is separate on that CTEK model IIRC.

OP: Sounds like a trip to camper forums might be worthwhile. You might shudder but the VW T6 forums have loads and loads of this type of install all with smart charging systems for AGM batteries. They'll also likely help you out too - same thing, different badge.
