Cbe 100 problems

Its definitely sensing the alternator charging just not switching back when the voltage drops when it stops charging.
Unless I disconnect the signal so for some reason the voltage drop is not enough for it to switch.
 
Only really noticed this happening since we started going off grid and couldn't use the lights so could have been happening since it was installed hense me questioning if it should be connected to the ignition wiring.
 
Just found this wiring diagram so I think I've answered my own Question and the company who installed it wired it in to a permanent live and not the ignition circuit.....

I'm really confused. Are you saying the converter took a constant supply to pin one of the connector J01 in your wiring diagram?
If so, this is obviously very wrong, but you would always have had the problem that you described in your original post!
What changed?
 
What changed was we went off grid where previously we where always on a hook up so it masked the problem...I've traced the signal wire back to here and am currently poking it with a screwdriver lol....

(PCT Volton Relay) I am presuming this is the problem as its not switching even when I try to adjust.....I know its there to sense the vehicle battery drain and isolate it when it gets to low but is it normal practice to connect the signal wire to it or is it they have just been too lazy to find an ignition feed.

I'd have thought that you'd get mixed results with any van that is EU6.
Certainly on T6.1 vehicles, the voltage dips under 12.2V whilst driving at times, making volt sending kit tricky to make efficient use of.

Is it difficult to run a proper ignition feed?
That is what I'd be looking to do.
 
As far as I know there is not a smart Alternator on this van as its not got adblue so that shouldn't be an issue but the voltage isn't dropping enough to switch so it still thinks its charging.(another reason why we didn't see this because I've only recently changed the battery as it wasn't holding a full charge)
Currently on the search for something ignition operated that I can T into near the rear of the van which isn't as easy as its sounds when its fully kitted out...lol

Check the V5 vehicle registration document, if under 4.Vehicle Details, D3 Model the letters ‘BMT’ are shown it’s a Bluemotion model which has a smart alternator.
Some Euro5 models (no adblue) are Bluemotion models.
