17 Studie...sorry for the long delay...winter in Canada is no fun and not much work was done on my 16 Roadster. Short answer is while their is a local museum here with a big restoration shop that thought they might be able to fix my original relay I decided to do what others have advised and I bought a 6 volt cut-out relay. My roadster is in show room condition but I am having trouble getting spark still (see my above post) so I have to find time to get after it. BTW...my Studie was built in Brockville, Ontario, Canada and shipped to Australia...it is right hand drive!!!!! Rick.
