I plugged a phone charger in the cigar lighter wich worked then in the power socket and not working.
Used the horn fuse (also 15A) instead of the socket fuse - not working. Put the socket fuse in the Horn - working. So not a fuse fault.
Need to get a Multi Meter. Any recommendations?
I know this is an old post but I blew the fuse on one of the 12v sockets in the cab today and the advice about not relying on a visual inspection of the fuse saved me countless hours of faffing around looking for another cause. I put my meter across the fuse and lo and behold it HAD blown even though it looked fine.
