Hi all, new member to the forum, friends call me Tuggy.
I have a motorhome based on a Ducato 2.8jtd. When the engine is started the habitation 12volt is switched off automatically and the step also automatically retracts if you have forgotten to do it.
This has just failed and I'm struggling to find a failed relay or loose contact. The Bessacarr 725 manual only deals with hab stuff and the Ducato manual only deals with the base vehicle. Neither seem to deal with the interface between the two.
I don't think the problem will be individual to step or hab electrics but something further back up the line that affects them both.
I've checked all visible connections and fuses under the hood but have no idea where the relay in question is positioned. Can anyone help please?
I'm guessing it will be a 'normally closed' relay that opens when it detects output from the alternator? I'm no mechanic but blessed with decent common sense. Quite able to use a multimeter if necessary.
Thanks for any advice.
