snail Posted April 13, 2023 Author Share Posted April 13, 2023 Morning again guys, bit more help needed! Firstly to fully remove the seat I need to disconnect the air bag connection will this then cause a problem that needs to be reset on ecu? Now I have the seat laying back onto the bed I can see much better, the installer has not used heavy cables to the battery, brown and black wires I guess about 5mm and run two of each to double up To the 40 amp fuse and then a short 16mm red from fuse to battery live! I am assuming it should all be run in 16mm so it's turning into a bigger job than expected, now the seat will have to come right out to access back to psu and charger, hence the question about airbag wires Thanks Link to comment Share on other sites More sharing options...
Hans Posted April 13, 2023 Share Posted April 13, 2023 I've placed 2 SuperB lithium batteries of 100Ah. Stand off grid more than 3 days in winter (compressor fridge and Webasto heating on) ! No more problems ! Link to comment Share on other sites More sharing options...
Hans Posted April 13, 2023 Share Posted April 13, 2023 I have also 150 watt sun panel on the pop up roof. Link to comment Share on other sites More sharing options...
Hans Posted April 13, 2023 Share Posted April 13, 2023 Extra Info.The above VW transporter seats can be turned 180. And are made by Faurecia, The fiat ducats is larger in space so you can put a larger amp in it. It is not a DIY job. But i are aware what sits under these seats and safety rules.

Hans Posted April 13, 2023 Share Posted April 13, 2023 Forget to say that an induction cook plate is a nice fit. And all is related to batts under the front seats. Link to comment Share on other sites More sharing options...

You will have to disconnect the starter battery before unplugging the SRS wiring to the seat to prevent codes. Follow the instructions in your owners manual for how long to wait after turning the ignition off or having doors open or closed when disconnecting to prevent other faults! Keith.

Robinhood Posted April 13, 2023 Share Posted April 13, 2023 As Keith said. You might get away with it (any codes generated might well reset when everything returned to normal) but playing with that wiring is not something I'd do without disconnecting the starter battery (and any solar panel too if it is set to charge the vehicle battery). Whilst I'll not claim it is definitive, this is what I did on replacing the airbag ECU: Quiesce all vehicle systems and leave for 5 minutes then remove vehicle battery earth - Remove the battery cover , close all doors and windows, activate the central locking with one press, key out of ignition, wait two minutes, ( wait seven minutes if the ign has been on). All modules are now in standby mode, disconnect the battery negative quick release, exit via drivers door, lock with key. (I left everything to quiesce by leaving via the hab door, since it's a coachbuilt, and then re-entering the same way some time later. Opening a cab door starts everything up again). Do all your work, then: Reattach vehicle battery earth - When reconnecting enter the van using the key , close drivers door, connect negative cable, wait one minute, carry on as normal. Its possible the alarm will sound, cancel with the fob. Link to comment Share on other sites More sharing options...

Hans Posted April 13, 2023 Share Posted April 13, 2023 And when they are fully loaded . Pullout the loading cable. They do not like to be Hanging on all the time Link to comment Share on other sites More sharing options...

I am assuming it should all be run in 16mm so it's turning into a bigger job than expected, now the seat will have to come right out to access back to psu and charger, hence the question about airbag wires Thanks It's now dawned on me, these cables feeding the leisure battery must have been installed by Autocruise/swift, I am very surprised how small they are? The live side has two brown cables doubled up to the 40amp fuse then to battery, while the negative is one larger cable? The ec400 has the ability to connect a solar panel so am I to assume the original cables should be able to cope with solar and mains charging when on ehu? Do I need to change these cables to something much larger now fitting two 80amp batteries? The solar installation done by Somerset with 100 watt panel and epever duotrace dual controller is not connected to the solar connection socket on the ec400, it's piggy backed onto the wires coming from the ec400 PSU that go to leisure and vehicle batteries I'm unsure if I'm worrying too much but I would of expected much heavier cables after all when I fit the new AGM in parallel they will be joined with the normal automotive battery cables from Halfords which will be much heavier There is so much info on line it's hard to get a definitive answer everyone does things different and of course there way is best What's your thoughts gents?

snail Posted April 14, 2023 Author Share Posted April 14, 2023 Can we get back now please , my dilemma is basically cable sizes, so what do you think, stay as it is, or go bigger, or another thought to reinstate the ec400 to original, (remove the pigtails wiring ) and go straight to batteries from controller with bigger cables Over to you gents, thanks Link to comment Share on other sites More sharing options...
colin Posted April 14, 2023 Share Posted April 14, 2023 Your cables should have been sized to take the current from charger, our charger puts out 18amp iirc, yours might be similar, but I don't know the swift setup Link to comment Share on other sites More sharing options...

So if on ehu and with solar 25 amps max combined, do you think I'm over thinking it and should just put the agms in and forget it? Link to comment Share on other sites More sharing options...
