Who needs 12v
Posted: Mon Aug 30, 2021 2:10 pm
Completed a full restoration on my SC about 12 months ago. I had always had problems with the sluggish starter which left me wondering if i should upgrade tp 12v. Enquiring on the forum the advice was if its set up correctly 6v is perfectly adequate as Porsche intended.
So as part of the resto the starter was rebuilt as was the dynamo. In addition i double earth strapped the starter motor to the bodywork and double bolted the battery earth lead using a copper strip. I also fitted a Rally style battery master switch as an antitheft device and a way of ensuring no battery drain whilst not being used. As a result my starting problems disappeared and the starter flies over.
For reasons i cannot understand i have not used the car for the last 3 months but today i wanted to take it out for a blast. To my astonishment once the float bolts were full it fired up like a good un. The only concession i made was to fit LED headlights to improve night time visibility.
So if you are contemplating the very expensive conversion to 12v think again. Just do everything you can to ensure the existing 6v electrics are set up right, particularly a good earth, and you should not have any problems.
