factory fit aux battery

Gday from down under Does anyone know if a faulty aux battery relay from factory would cause the battery light illuminate on the dash. When it does do this I can hear the relay tick as the light comes on. After starting the van, about 30 seconds later the battery light comes on which as a...

This is my current set up in my 2018 Caravelle, a mess of wires of a Factory specced Eberspacher Auxiliary air heater and 2nd battery, plus a few extras fitted by the previous owner, all under the passenger seat: This is the wiring diagram as it sits: I've got the standard split charge...

Hello everyone. This is my first post here. I have just bought a 2016 vw Multivan that I plan to use as a weekend camper. Some of my planned modifications are to install a webasto diesel heater under the car. I am trying to find measurements and drawings, possibly a 3D drawing, for the...

On my 2023 T6.1 both the cab sockets were factory wired to the factory fitted leisure battery. I‘d like to know if this was a standard change from T6 to T6.1s (2019 onwards) or whether it “just depends” on equipment fitted. Advice is often that you can charge the starter battery from one of the...

Under my passenger seat I have what looks to be a 10mmsq cable which I’m lead to believe can be used for a DC-DC charger, negative coming from chassis. I was originally thinking of a Victron 12/12/30 unit which would be mounted in a cupboard I intend to make and located under the non sliding...

All, I specced my van with a few extras when I ordered it. One of them was a 2nd battery under the drivers seat, I am intending on using the van as a camper at a later date but for now it’s primary use is for work and a day van. At present nothing is running off this 2nd aux battery but I’d...

Hi. I have a the set up as shown in the photos and would like some info if anyone can help please. Where does the feed into the split load relay come from as it is not connected to the battery terminal, and what might be the length/ route for the cable? I would like to fit a proper leisure...

Hi, I had the factory fitted aux battery ( under a single seat with swivel base ) fitted to my T6.1 with the intention of using it as a camper leisure battery. After getting less than impressive performance and reading about how the split charge relay is a pretty bad charging method I wanted to...

Good evening all I'm hoping somebody will be able to point me in the right direction quite easily - I want to connect a leisure battery to my new Renogy DCC50S charger. My initial thought was just to run a fresh cable through to the starter battery in the engine bay, but I've found some cables...

Hi I have a factory fitted leisure battery on my 2018 T6 Kombi, however it doesn't appear to be connected to anything. I don't get a relay click from the leisure battery when I turn the ignition, nor do I have any 12v or 240V sockets in any of the pillars. I think I need to find a conversion...

Hi. I’m away now for the second week in my van and it seems my factory fitted second battery under the passenger seat is draining as well as my main battery. I haven’t run the van since arriving. I assumed the second battery was like a leisure battery so am puzzled why the main battery should...

I know this subject has been covered to death but I don't know what you do regarding the OEM relay. So my van had the 2nd battery and I am planning the electrics going forward, I am going to put a lithium under the driver's seat hopefully and use the OEM wiring. So what do you do with the...

So I have had a look at other threads but couldn't find the answer, does anyone know what these wires/ fuses do under my passenger seat please!?

Hi, I'm new to the forum and have a question regarding my 2022 T6.1 Kombi. Under the single N/S passenger seat of a RHD Kombi is a long slim fuse box. This is fed by a fairly thick red wire which is permanently live and terminates and splits into a slightly thinner one and three thin ones which...

Have looked at previous threads and some seem to conflict with what I’m finding. 2023 T6.1 Hillside Birchover Classic campervan; uses standard VW factory fitted aux battery fitted under passenger seat. I’ve just measured the voltage on both the upper and lower cab 12v sockets both with the EHU...

I have a 2016 T6 which when I bought it had a small 300w inverter fitted in the base of the passenger seat. I removed the inverter and refitted all the other wiring in the passenger seat bin under the front mat and some of it across to under the drivers seat when I fitted a passenger seat...

Hi, now on here and thanks to everyone putting on great info. Picture is factor setup. Anyone know what the bank of three blue fuses are and more specifically the blue connector - the blue connector was disconnected when I got it. All three wires come off the battery and go down into floor -...
