Hi all, Whilst trying to sort out my dodgy fuel gauge issue, I came across a faulty 10 amp fuse under the bonnet of our Ducato based Hymer. Now despite two new bulbs being fitted (they worked at the time of fitting) to the front fog lamps a while back, , and very little usage since, they haven't been working for some time.........until I replaced this little 10A fuse. :Eek!: The Fiat manual places the front fog lamp fuse on top of the relay, under the lower dashboard. This isn't so in my case. Anyway, having got my front fogs working again, I noticed that the green warning light wasn't illuminated on the instrument panel. I disconnected the speedo cable at the gearbox and withdrew the binnacle to gain access to the bulbs at the back. I swapped them over into different circuits to test them all. They are all okay. I unplugged the multi plug for the warning light and fuel gauge circuits, and the replaced it again. Still no green light. Does anyone know please, why the warning light for the front fogs won't illuminate? My last thought is that it could be a faulty switch on the upper dashboard. Any more ideas please? Thanks in anticipation, Jock.
