12 v lights and oven fan won’t come on 19 plate fiat rimor I can’t find the fuse box

[johnbrennan]

I’ve got a 19 plate fiat rimor europa 3 of the under cupboard lights and hob fan won’t come on I’m sure it’s a fuse but can’t find the 12 v fuse box I’ve checked every fuse I could find does anybody have any idea what I could don

It tends to be on the charger unit, which is normally beside the hab batteries

Most motorhomes have a distribution/fusebox that has several 12V fuses for the habitation circuits. It also contains things like relays for the charger and fridge, and often has the mains trip switches and mains charger as well. The box may be hidden away in a locker or cupboard. Usually it has a wire to the display/control panel which is in a prominent place. So when you say you've checked all the fuses, did you find the ones on the distribution/fusebox?

Hia thanks for your reply I’m a complete novice I’ve opened every cupboard and dismantled boxes I don’t know what to do

I’ve found a fuse box by the batteries and all of them are good

Does it have a manufacturer name/model number? These boxes are usually bought in by the motorhome manufacturer, and are made by a few specialist electrical companies like CBE, Nordelettronica, Reich etc.

When you checked the fuses was that just a visual check, or with a meter? Sometimes they look OK but a meter shows they are no good. If no meter you could try swapping in a new fuse to see if it works. Do you have a multimeter?

They might be under a panel at the bottom of a cupboard

Like the OP, I'm having trouble finding a certain fuse in my Elddis even with a multimeter. The continuity checker uses an audible noise, which has never emitted a single note. There's no visual display that I can find on it. It's the standard cheapo but not the cheapest. I assume you need to put a current through the fuse and it should show by glowing a light.

I do not have anything else to hand on site. So where would I find a fuse upstream of a solar controller, that is between the panel and the controller on an Elddis?

The continuity checker function is a convenience, there are other ways of checking continuity with a meter. The continuity checker should emit a tone when the two probes are touched together. If it doesn't, the continuity checker is not working.

An alternative method is to set the meter to the lowest ohms range, usually the 20Ω range. then touch the two probes together and see what the reading is. Some meters will read zero, some will read about 0.2Ω to 0.3Ω.

Then measure the resistance of the item you want to check the continuity of. If it's a wire or fuse, and the resistance reading is still below 1 Ω, then quite likely the continuity is fine. If it displays OVL, OL or whatever you get when the probes are not touching anything, then there is no continuity.

I will attempt to do that. Thanks. I went through replacing the most likely fuses on the main power unit simply because I have come across the issue of the fuses looking good but are in fact blown. But to no avail with the solar controller.
