After checking every component of the ignition system Friday night and not finding any obvious failures, I decided I had nothing to lose by pulling the distributor and checking it out. Not sure why, but fooling w/ the distributor was always one of those things I avoided for some reason. Fear not friends, it's not brain surgery and I finally found the source of my Saab woes ongoing for years now...
Upon removing the field rotor in the distributor, I noticed that it was, for lack of a better term, warped. Each one of the fins that pass thru the Hall sensor looked like it was rubbing on the Hall sensor from the wear marks on the inside of the fins. The field rotor must have gotten so far out of round that it hit the side of the Hall sensor and seized the field rotor. The locating pin (to me appears to be functioning as a Woodruff key) was MIA, later to be found in some gunk in the bottom of the distributor casing. This is obviously the cause of the lack of spark I've been tracking down for the past week. What still perplexes me is the amount of rust that had developed on the field rotor inside the distributor.
Now that I think about it, I should have pulled the distributor long ago, given that in the years I've been wrenching on motors, it's usually the rapid moving parts that wear out first. It really was not much different than a commutator set-up on a lawnmower engine. I find myself sanding the rust off of those every spring before mowing even though my mowers are stored indoors for the winter.
Now the challenge becomes finding the best deal on a replacement distributor or even better, all I really need is a replacement field rotor for the inside of the current distributor. Are these available? The Bosch part number for the distributor is 0 237 507 008.
For those of you trying to find the numbers off of the Hall sensor, these were easily readable, the sensor part number is 1 230 500 221, the connector number on the Hall sensor is 1 230 329.
