    Hello everyone, id like to start by saying that this site has been amazing for tips while building my wfp system, especially things like the guttering hopper to fill your di's. Amazing idea (and easy to pick up from wickes last minute!).

    Again, im sorry to post a question for my first post, but im panicking.

    Im going out tomorrow with the set up for the first time. Ive built it myself but its engineered to a high level. I have a new way of bolting a tank to the chassis in a vivaro ill share when i have more time next week.

    Ive fitted a TCW controller with charging relay (v11?). Tested it yesterday. All working fine. Ive looked in the back today and noticed that the controllers still flashing CHG even though the ignition is off :(

    All wiring is 100% correct, i believe. Im thinking it may be the terminal on the van battery ive picked. Has anyone had this issue? Ive tried searching with no luck.

    I was advised by my neighbour (old and wise) that the larger cable would probably be to the starter motor. I had it on that originally but had the same issue. Tried it on the thicker one and its the same.

    Am i right in thinking it shouldnt be saying CHG when the van isnt running?

    Any advise would be great, im scared of having a flat van battery on my first day with my new kit :(.

    Cheers

    Chris

    Never be sorry for asking a question Banesthename (second best Batty villain after Heath Ledgers Joker) and welcome to the forum.

    You are over my head on the techy wiring stuff but hopefully spruce or AGlassAct should be along soon and they know a thing or two about wiring.

    Welcome once again.

    Once the engine is switch off the 'join' or link between the leisure battery/aux battery should be separated. I don't know what colour wires your controller has for the charge relay side of things. Your manual you got with the pump will tell you. The charge indication should only be visible when the engine is running, so something isn't right IMHO. (But I don't know the controller.)

    However, my first major concern is that you have used an industry standard earth wire (green and yellow) as the positive lead from the battery. This is never good practice tbh. (Brown = positive, blue = negative and green/yellow = earth/ground.) It looks as though you have used ordinary 3 core 230v electrical cable which also looks to thin for the job if its a standard leisure battery.

    You need to go back to your manual and confirm you have wired the controller up using the correct wires. If you are using different colour wiring its easy to get mixed up.

    If you can't solve the problem then you need to contact Ian Sheppard at Spring who make those controllers.

    Thanks a lot for the reply spruce. Its much appreciated.

    I dont know if you can see on the pic but i put a piece of coloured shrink tubing on the cables so i know which is which. The earth cable has red on and the blue has black. It was literally to save me stripping another 6m's of outer cable off to get another brown out. I can change this, Ive used 1.5mm. The cables on the controller are all that i believe.

    The pump has a blue and brown. Ran totally seperately in small copex.

    The remaining cables left on the controller are black, red and orange. The orange, is the positive fused cable that runs to the earth cable i used. The red (ive used brown) runs to the lesuire battery positive. The black (ive used blue) runs to the lesuire battery negative. There is then a blue link (negative) between the two batteries. It should all be connected up as in the diagram. It all works connection wise, its just like it cant see that the ignition is off.

    I can change the cabling for 2mm or something?

    Ive added a picture of the controller cables. The connection block is housed in an ip box in the rear light pillar.

    Also attached a picture of the instructions. Does it need to be on the alternator or something? If so why do they say to connect it to the battery?

    It definitely wasnt doing this yesterday when i tested it. None of this CHG flashing.

    Any more ideas? Sorry to be a pain. It was all going so well... Probably wont be running tomorrow at this rate :(

    Turned the controller off. Nothing displayed. Started the engine, chg initiated. Turn off ignition, still says chg.

    No idea.

    My controller flashes CHG after the ignition is turned off. I'm not technical but I presume it's a current still flowing. It does go off after a while though.

    i have a vivaro mate,its one of the easiest to wire up but it looks like you have a newer model than mine,personally i would have a thicker wire/cable coming from the battery coupled with a 30 amp fuse just after the terminal and one before the leisure battery,the spring controller suggests its not getting a charge so that maybe your problem-it should cut off at 11.5 volts,
    just check with a multi meter your getting 14 volts or higher from that cable with the engine running,and at the end where it connects to the controller-before the fuse
    also,and its something so simple but can give loads of issues buzz out or check every single earth you can and read the ohms to check resistance
    i think your problem is a simple one but just needs thinking about thats all
