Missing leisure battery supply

[Siblo]

Hi All,

Hope this is in the correct area, (admin please move if not)

I recently fitted a new shower room in my Lunar Newstar Ducatto, it was old and tired and showing its 15 year age, so I ripped the lot out and replaced with a flushing toilet, flip up sink and large shower tray, now there's plenty of room.

Unfortunately, in the process, I had to lengthen a couple (few) wires which ran from behind the Power Management system under the rear u-shaped lounge, through the gas cupboard, or behind the fire, not sure which yet, and UNDER THE OLD TOILET AND SHOWER,

When parked on the drive, I wrongly assumed everything worked, but that was because I was on hook up.

Now without hook-up, with the switch on "car", all 12v systems work, with the switch on "van" I get nothing.

If I plug back in to a mains supply, I get all 12 and 240v no matter where the switch sits.

I'm assuming that when I extended these wires to follow a new route I badly made one or more of the connections, so here's my questions....

Which wires would run to the Habitation battery from the PMS, and visa versa? I'm going to check tonight but I think there were 4 or 5?

And does anyone know the wire colours used by Lunar? Or are standard colours used to give me a starting point?

Thanks in Advance

Simon

If the battery was still connected when the wires were extended you may have caused a short and blown the master fuse near the battery.
It should be a large, maybe 50 amp, fuse and very close to the battery POS terminal

What make and model PMS do you have fitted.

Hi and thanks for the reply's,

Yes going to check for an in-line fuse near the Habitation battery, none on the PMS have blown.

Images are of the PMS, just marked PMS4, can't see a makers mark.

Hopefully it will be the main inline fuse that is the problem (In case you need to know , for any reason in the future , the makers of your system was called Plug-In-Systems Ltd , PMS4 is the model type)

Update guys,

Yes it was the master fuse, thanks for the pointers guys.

Main hab battery is under drivers seat, when I added another under the passenger seat, I now remember seeing it, 'twas a bugger to get too though, now re-positioned so I can access the fuse with the seat rolled forward instead of actually removing the seat like I've just done.

Once again, many thanks to Pappa, and to Geoff for the info on the PMS for future reference.
