Technical D+ short curcuit. How to find the 2A fuse? 2021 Ducato

[Communicator]

Hi , I have read your post and we have the same issue with our fridge not working on 12volt. We also have an ebl630.
Did you manage to resolve the issue and find a company that provided a KM630 module ? Thanks

On post 2006 Ducatos there is an option for a converters panel at the base of the RHS B pillar. This panel provides an interface with the vehicle systems including 12V power for fridge and battery charging. The D+ output on this panel is active low, which means that it connects to 0V or earth when engine is running. If your Schaudt EBL630 is not set for D+ active low, then it will not power the fridge 12V element.

I don’t have much knowledge in regard to your post. Why would the Ebl 630 change settings to D+ low active ? Do you think it’s a problem with the ebl 630 ?

We have a 21 plate Burstner

No solution currently as I am still away from home but A&N Caravan Services advised that the KM630 module cannot be repaired. As replacing the unit requires ordering from Schaudt via a main dealer I think a simpler solution is to bypass the module using a standard 12v relay picking up the D+ signal from the alternator. I intend trying this when I return home next week and I will report if successful or not.

I noticed the photo to where your KM630 is positioned in your MH. We have a 736 Burstner and the floor storage doesn’t have a small separate panel like yours so may have to search to find it !!

Did you sort out your 12v fridge issue ?

I am sorry I seem to have missed your query. You are have obviously failed to understand the situation. It is not the EBL 630 that changes the setting it is the installer. It requires human intervention. If the EBL 630 is connected directly to the Fiat converters panel, then the EBL 630 D+ selector switch must be set to Active Low (Bas). This action needs to be undertaken by you if it is not set correctly.
