Fuse to coil keeps blowing

Thanks Dave for your prompt reply to my problem. I found the wiring diagram in the back issue which has helped as I didn’t realize the brake lights were on the same fuse. The previous owner has installed an extra pair of brake lights, so with four filament bulbs that’s nearly 14A just for the brake lights. I’m thinking about removing the extra pair anyway.
I’m not an auto electrician but there seems to be at least one mistake in the wiring diagram as connecting terminal D to H seems to connect the side light switch to an indicator. However that’s not a problem for me as my car doesn’t have any terminal blocks, maybe because it’s a Belgian built one perhaps.
The other funny thing about the diagram is that the panel lights are shown connected to the fuel gauge which would surely mean they were on all the time the ignition is switched on. Again not a problem for me as mine are wired to the light switch.
Again many thanks for pointing me in the right direction.

Folks,

Just a note on blowing fuses: a fuse is put in-line to protect a circuit from overload or short-circuit. There is a significant difference between a fuse that has blown from an overload and one from a short circuit. A fuse that has blown from an overload, tends to have done so slowly and if you examine the fuse, you will find that it has just melted in the middle, leaving the majority of the fuse element intact. If a fuse blows due to a short circuit, which generates a huge inrush of current, the fuse element tends to completely evaporates, leaving a nasty black sooty deposit. With an overloaded circuit, you can risk replacing the fuse, but when a circuit blows due to a short circuit, you must never replace with another fuse until the cause is located and remedied.
