it turns over but no spark.Have manual but, confused. No spark at plugs, coil packs, switchbox. tested stator and metered 800 ohms. chart ranges 800-1100 other wires to grd tested no continuity. tested trigger coil-purple to wht: 798 ohms. brown to wht/blk: 793ohms... not within range(1200-1350) appears to be bad... am I missing any tests? also when testing ignitiion coils, the book mentions how to test but which is the primary side of the coil adn the secondary? I have two screw terminals on the coil packs one is attached to switchbox and the other attached to grd. (it was running at low to no mph for 30mins+ turned off to remove driftsox and never did she start again!!!)
