no relays required.

A 15A fuse would be a good idea if the LR fuses aren't present.

Just a case of earthing one wire to body, and soldering the other wire to a wire on the grey plugs.

the thick green/brown IIRC

happy days Bow down

have got a spare megafuse holder , can easily get the 15amp fuse for that and are only a couple of quid

will be a job when i’ve got the other bits finished i’m currently doing , replace the faulty T max solonoid and finish off the front struts, front drop links and anti roll bar bushes

am considerably the wiser though that’s for sure and just can’t begin to say how grateful i am Pete for u taking so much time explaining all of this to me Thumbs Up Bow down

will have to sit down and work that out ref the wiring , unless as ur saying it’s just one wire from the 12s socket to that grey socket in order to pick up the power feed just for recharging purposes , sorry being a bit dense Laughing

thank u so much Thumbs Up

something like this:

Yeah its just pin 3 via the black wire to chassis earth
pin 4 to thick green/brown, with the fuse inside the car

this is what i’ve got

https://www.ebay.co.uk/itm/Midi-Car-In-Lin...SwiBJZ65XU

but also got a spare one as per ur link , so will use that , even have some fuses too, Laughing

that’s great , i think i’ve even got a 12 s wiring diagram Whistle

sorry as i didn’t realise it was just running 2 x wires , thought it was considerably more involved , ie wiring up the entire 12 s

will get the bits ordered up now and then order some cable , 3 x metres of the twin cable should be plenty shouldn’t it plse

see there’s an earth post right by the boot pully , so perfect for the earth

will be great getting this in, will just have to also order a ctek - 12s converter plug

Thumbs Up Bow down

PS, may i ask plse , does it matter for the mot that the 12s won’t have all the wires , haven’t got a tow fitted

just realised

i’ve got some short spare rolls of 12 volts cable

17amp. 3.5 metres long x 2 rolls
27 amp 2.2 metres long x 2 rolls

wondering that would be ok to use wouldn’t it plse , just need to install the lower 15amp fuse

also got some spare sleeving , heat shrink etc

thks Thumbs Up

Yes you could use that.

I don't think they test the 12S at the mot. In any case just put the cover on.

Hi pete

wished to say a massive thks, all the bits arrived, just ordered some extra conduit , can then get it wired up

just appreciate the great help you’ve given me Bow down

got an email from Ctek as i asked a good while back ref the extension lead

HI!

The original length of our Extension cable 2.5m is dimensioned to what our measures allows the max extension to be. We do not recommend longer extension than 2,5 meter.
This is because if the distance is longer, the charging quality will be too weak as there are losses along the leads and the connector, and the voltage that reaches the battery will be too low to fulfill the CTEK requirements for charging.

Best regards, CTEK SUPPORT TEAM

I guess they are worried their cable is too thin.

You could always make your own extension using thicker cable from the towbar plug

I charge 2 cars from the boot, so I have the whole length of the car to contend with and have no issues. Car wiring is double the thickness of the CTEK extension though and local earth.

So best to make your own.

Gary google 12 volt nomogram and get reading, it will keep you quiet fro hours and is actually quite interesting but not for to long as it made my brain fry!

The white fuse adaptor is belt a braces should a fault happen while you are testing, which is unlikely.

It sounds to me as if you haven't set your volt meter to a low enough range. 200mV I think is required.
They can't all be reading zero.

Test/practice on the 20A suspension one.


thought that about putting a socket outside , just thought it easier i can then hide the ctek in doors , ie if i go out with the dogs

didn’t realise at first the ctek short lead i’ve connected to the battery has small lights on it

the zero readings are when i set the meter to ac, for the alternator test

i will recheck the meter ref it’s settings, i did use my other multimeter to double check every small fuses and after the time out everyone showed zero , just in case i need to double check them to ensure they making contact with the meter probes 100% on the small fuses

these are the meters i’m using






Not sure if this will help, but i posted a short run through on what i did to help find my drain.
I found reading via the main earth cable was more consistent. Also didn't see in this post if you had closed out the bonnet open switch. If you close the bonnet catches with a screw driver it will allow the ECU's to go into sleep mode after around 2 min once you lock the car. You can then see what the drain is and i closed the door catch to allow access to the passenger footwell and fuse box. Defiantly worth removing the Fuse links first if you still have a drain above .5a

Hi pete

indeed, suppose there just trying to cover themselves Whistle

many thks, that’s a good idea ref the lead , may i ask what cable did u use plse to make up ur extension lead Thumbs Up

plus i made up my towing socket today

couldn’t believe the hack on the existing loom someone has done, madness as there’s spare connectors on the end of the 12n and 12 s wiring looms

enclosed a pic of what hack was done , Censored
