D+ or Engine Run Signal for DC - DC charger.

[Travellingtaff]

Hi All, I'm a new member to this forum and my problem is how to pick up a suitable engine run signal to activate the DC to DC charger. A couple of members suggested a new post but they did say that I could pick up a 12 v o/p from the central fuse box. However I have no idea which fuse and how I could make a connection to take of the +12 volts. Grateful for any help....TIA

Just looked at the V5 and its actually classed as a T30. Does that help ?

 

[roadtripper]

T6 or T6.1?

 

[Travellingtaff]

T6 or T6.1?

Well its an ex British gas van with 2 sliding doors...I think its a T6 but its a friend of mines van and she's bringing it over tomorrow so I can take some pics of it.

 

[roadtripper]

Do you know the model year?

 

[Travellingtaff]

Do you know the model year?

Yes its a 67 plate...(I think thats Dec 17) and she thinks the model is actually a T6.1

It is a T6 @Travellingtaff .

John.

 

[Travellingtaff]

Oh Many thanks for that...she wasn't absolutely sure tbh

 

[Rioja John]

If you look at my avatar which is a T6.1 you will see the difference.

John.

 

[Travellingtaff]

Ah yes, I can see the difference

 

[roadtripper]

And what cabling/leisure system do you have in already, or are you starting from scratch?

 

[Travellingtaff]

Starting from scratch....Pretty up to sped with the electric installation, helping my friend build the panel but its just this D+ feed to the charger I need to find.

 

[roadtripper]

So you have a fused high current feed in from the starter battery? If not it's much easier to put the ignition signal in at the same time while you have the floor up.

The easiest way is to get one of the fuse taps like this



You should place it in the orientation as noted by @Deaky in this post to ensure the original and new fuses are in the right circuits:

CTE D250SE ignition cables

Hi all, I am currently trying to fit the CTEK D250SE to my T6 and I’m hoping for some clarity on the ignition cables. I have a dual purpose flooded lead-acid leisure battery and am wondering do I fit the black ignition cable to ground and the red to the fuse board or is that only for AGM...

www.t6forum.com

In the dash fusebox the upper half of the centre column should be ignition switched. If there is an empty one you could use that as there is a common positive bus bar and the fuse tap will work, even without the other connection, and this will not disturb any existing circuits.

(If you want a very neat job you could install the socket in an empty fuse way and avoid using the tap, but that's more fiddly)

I'd double check with a multimeter at this point that you have an ignition switched feed to save confusion later on.

You should then be able to run a signal cable to under whichever seat you are installing your charger following the cable loom under the floor.

That great ! Many thanks for the info and advice. I'll give it a try
