Thank you for your help.
I had recently renewed my battery and the new battery did not fit the tray correctly.(I was sold the wrong battery).
The battery had moved slightly and the live terminal had touched the battery clamp which caused a direct short.
I then telephoned Yuasa technical dept to find out the EXACT correct battery for my car. They said a YB5063.I have just received the "correct" battery which now falls through the tray.
Tomorrow I will cut a piece of ply to sit in the battery support frame.Back on the road this weekend-yippee!
Yep.....exactly what I had to do on my Roadster when I replaced my battery with a Yuasa! I had just cut the ply and soaked it in Cuprinol ready to fit when I bust my ankle that afternoon. The battery still sits on the garage floor!
