coxy123 Posted February 13, 2016 Report Share Posted February 13, 2016 On my 1978 Spitfire there is only 2 fuses, the 3rd has a broken holder and at some point in its past it has been replaced with a loop wire and an in-line fuse. All the electrics work correctly, My question is, is it worth it and how hard is it to replace the fuse box. Link to comment Share on other sites More sharing options...
John Bonnett Posted February 13, 2016 Report Share Posted February 13, 2016 Now might be an appropriate moment to consider fitting more fuses and protection. In the event of a short circuit, the insulation on the low rated cables will melt and burn before the three twenty or thirty Amp fuses blow.

dougbgt6 Posted February 13, 2016 Report Share Posted February 13, 2016 Easy enough to replace but well worth upgrading. Your head lights, for instance, have no fuse at all! All the current for the headlights comes directly from the battery, through the head lamp switch and on to the head lights. John beat me to it!

Clive Posted February 14, 2016 Report Share Posted February 14, 2016 Replacing the fusebox like for like is very tricky. Mainly as the wiring loom runs through a hole in it. One way of fixing it is to replace with a Mini fusebox and the existing wire terminals (which double up as the fuse holders) are replaced with 1/4" spade connectors. Or indeed a bigger fusebox as above. And if feeling good about that, add a few relays...... Link to comment Share on other sites More sharing options...
dougbgt6 Posted February 14, 2016 Report Share Posted February 14, 2016 "Mainly as the wiring loom runs through a hole in it." Not on mine, my wiring connects to the back of the box and once the box is unscrewed from the bulkhead it and the attached loom can be pulled a good 4 to 5 inches forward, making detachment fairly easy. The only difficulty would be taking care to identify the cables for reattachment. Maybe it's different on a GT6? Link to comment Share on other sites More sharing options...
Pete Lewis Posted February 14, 2016 Report Share Posted February 14, 2016 yes spitfire has a nasty thing with a hole in to seal the harness /baulkhead GT6 and Vitesse were a bit more 'posh' Ha ! when we split the body tubs on the Vit6 I cut all the wires to add a full fuse box, but car was needed in a hurry and choc blockes were fitted as a temporary bodge Ive sold the car 2 yrs and guess its still got them ...hiding behind the battery Oops!!! one of them To Do lists that Dont Pete Link to comment Share on other sites More sharing options...
dougbgt6 Posted February 14, 2016 Report Share Posted February 14, 2016 Well well, learning something all the time! I've got all the bits to replace mine, relays and everything. Hope it doesn't fall into the "Round Tuit" list. (Never get around to it) Link to comment Share on other sites More sharing options...
