Thanks for this tip about my 850 with no spark. My manual doesn't have much for wiring diagrams (Chilton seems almost, but not quite useless.) It also does not mention relays.




Relays 101 thru 104 near the fuses are stamped with the numbers, but the remaining three identical cubes have no numbers on them. However, the stamped cubes look as if they are counting in a clockwise manner, so I surmised position 106 is the middle cube. I did replace it with one from the parts car, and do have power at the coil, but still no spark, nor did I get a code working either.




So I'm still puzzled about all this.
