Title: Capacitive discharge ignition Post by: j-f on March 02, 2021, 12:14:29 pm Hi,
I'm looking for a good ignition system and saw that CDI looks to be the more efficient for our flat4. I saw a few used Crane analog CDi on Ebay and wondered what kind of distributor is needed to work with that? I have an old Mallory YL dual points that I would like to use, but don't know what it takes to wire it to the Crane box?

5 years down the road, i am still using it, same set of points , mileage not much covered about 13,000km and it is still running OK. still on the same set of points, recent maintainence was change of new plugs and new diaphragms on the DRLAs. points still look OK , just greased up the points and refitted. plugs were BP5HS that i swapped out for some Iridium NGK plugs i never bothered with the car much as its more of a weekend runner, so i never explored much beyond that.

i wasnt keen on spending on the MSD and coil setup hence i went with the Winterburn box.

I had no idea the worlds first CDI was an invention by F.L.Winterburn in 1962 in Ottawa, Ontario, Canada.
