• Hi there Guest - Welcome to the New BCF!! This has been a long process and I'm sure there will be some kinks to work out, but as of today, Feb 22nd, the British Car Forum has been migrated to this new forum platform! There is much that is similar to the old BCF but also much that is different. Please give it a chance as with all things new and shiny it will take a little getting used to. However, I'm coinfident that, once you get used to it, you will find it a much more user friendly platform than the previous, outdated software.

General Tech Electrical question

Does anybody know a good reason why the positive side of the ignition coil is not fused.

In all the circuits I have seen the feed for the coil comes directly from the ignition switch and bypasses the fuse box.

That doesn't seem to be ideal to me.

Yes, I've always suspected that to be the reason. The fuses common in those days were not terribly reliable, and often "blew" for no obvious reason. That's a safety matter. I suspect that the headlights are unfused for the same reason. The unfused headlights and ignition are not uncommon in other cars of that era.

On fusing headlights, it's a matter of design philosophy, and there seems to be two camps on this question. Even the range of aftermarket fuse/relay modules is split on this issue.

One option: Feed the high and low beam circuits from different fuses.
