Spitfire voltage regulator

I finally got round to checking the voltage at the dynamo output and it was higher than the battery so I decided to give the voltage regulator a second look (it had already been cleaned and inspected) and I found that one of the contacts from the relay was broken so drilled the rivets to be able to take the contact part out and welded a new piece of coper in place.

The pic below will explain better, good news I now have an engine that charges the battery when it runs !
