1969 A65 Thunderbolt Blowing Fuse

[Wilf2019]

At least I have found the issue now. I found that one of the two wires going to the rear light had rubbed on one of the metal clips in the mudguard.

I have now replaced the wire and put heat shrink over the top where it passes through the clips.

All appears to be working fine now.

I think what threw me off from the start was the fact that the rear light and brake light worked fine without the engine running.

Maybe the exposed wire was only a small amount to start with.

Electrics isn't my strong point, but got there in the end with the help of this forum.

Thanks for all of the replies and suggestions.

Regards,
Wilf
