Fiat Ducato Fuse Issue

georgendah · 10-02-2013, 14:03

Hi all. Wonder if anyone can help me with some advice on tracing an electrical fault on a Sea Dinghy 2003 on a Fiat Ducato Base (1.9JTD). I recently fitted a reversing camera through splicing into the feed from the cigar lighter. Everything was working fine till the other day when I notice the wiring had dropped into view I had not noticed that the there was some copper protruding from the join and made contact with the live causing a fuse. I checked fuse the 15amp fuse marked 44 in schematic and it was not blown (I did replace it anyway). I note now that cigar lighter, 12v aux socket and heater are also not working so the question is what other fuse could have blown in the process?
Many Thanks Nev

its not uncommon for fuses to be marked incorrectly in a handbook. Try testing or replacing the other fuses of the right value, as its likely one is blown

Thanks Big 1 - I tried that no avail. I starting to think that because its not only the cigar lighter but other functions that it might be a bigger fuse in the engine compartment.

i think there are 2 fuse boxes one in the cab near the steering wheel, the other under the bonnet. mine has the cigar lighter and the aux power fuses wrongly marked.

I doubt very much the fuse will be in the engine bay...any fuses in there are usually reserved for engine bay componants...ABS module etc.

you need to remove each 'cab' fuse in turn and check with an OHM / continuity meter and not just a visual check...fuses can blow right at the end where the break cant always be seen

generally that is correct, except my fuses for the cigar lighter and the Aux power on dash is in the engine bay. Fiat Ducato x250 i had to find them as i had blown one useing a tyre inflator

Thanks so much for replies -perhaps someone could explain to me how shorting the lead I spliced from the cigar lighter to the reversing camera has put cigar lighter , 12v socket and heater out of action (could be more) whilst radio , lights and indicators still work!

generally auxiliary circuits are separated from main lighting
and indicators, which will also be fused seperately
