My main reason for sourcing these fuses was that fuse no. 12, dim/dip, had melted though the wire conductor was unaffected. I've now replaced with one of the ceramic type, and dim/dip duly functioned, but only for a short time. The fuse hadn't blown so I removed it and saw that the 'fixed' contact was very dirty, and had bits of the old aluminium conductor 'welded' to it. I scraped all that off, but the plastic around the fuse holder is quite black from overheating. I just wondered if the resistance of the old fuse could have caused that, perhaps because dim/dip is continuously on, unlike other components.
This doesn't matter too much as everything works as it should, but I have an enquiring mind, so any information from all you knowledgeable people here would be welcome. The new fuse is the correct 8 amp type, by the way; I can be a bit doolally but not that stoopid!
