Just don't try >ringing at lunchtime! Hey John! I've located a used hall-effect distributor from a 1985 Saab 900 and I will use that as a starting point to work out what else I need. I'll give the company you've mentioned a call too and see what they have got available. On Friday I purchased one of the Jaycar electronic ignition kits that I mentioned in the original posting and on reading the documentation, it can be set up to trigger from points set up, from a reluctor set up, and from a hall-effect set up, so it's quite versatile. When it's built up, the diecast metal box containing the electronics of the kit can bolt into the same place that the Bosch hall-effect ignition module is mounted in C900's which had it fitted from the factory... I have noticed that the Siemens HKZ-101 hall-effect vane sensors used by Bosch in the 1980's hall-effect distributors is no longer available, but I've been exploring data about hall-effect vane sensors from Honeywell and there are a couple of products there which look promising so I may order some samples and experiment with the soft-iron 4-slot vane out of a used hall-effect distributor with a Siemens hall-effect sensor. From some of the info discovered through Google searches, it seems that the most suitable Honeywell sensors operate in reverse (electrically) to the Siemens sensor, but that won't be a problem providing that the triggering points of the sensor can be kept the same. Adjusting a stock Bosch hall-effect trigger vane would be easier than making one from scratch. 8-) Regards, Craig. PS. For those in the know, what are the most popular methods of replacing the seals which go between the rear light clusters and the body metalwork on a non-hatchback C900? The rear light clusters on my 1983 900S are on their last legs and are leaking significantly when it rains, letting water into the boot space. I also need to look at replacing all the door seals as they are leaking too (the left rear footwell gets very wet when it rains), and also the internal door skins on the two front doors are looking quite sad. Can a Saab dealer take care of all this on a C900? Are there any 3rd-party places (preferably in Australia!) that make seals/gaskets/etc. for light clusters, doors, windows, etc. on these cars? -- Craig's Saab Page --> http://nospam/~c900 Sydney, NSW Australia Craig's C900 Workshop -- For all Saab 'Classic' 900 Enthusiasts world-wide!
