Thunderbolt type V system. Stator Question?

[ddonahue]

I have a 1978 700 MERC. I have no spark to my #3 cylinder. The plugs, wire, and coil test good. I checked my stator leads between the red and powerhead ground, it checks at 146 which by the book says good but when I check the blue and red stator leads they read 4.6 (book says 5.4-6.2 normal reading) which is low. Is this an indication that I need a new stator. Any other advice what it could be before I pull the flywheel. Thanks

Re: Thunderbolt type V system. Stator Question?

Thats the problem with OHM testing it's not to accurate, In most cases a stator will not effect 1 cyl. the problem will be a coil or switch box. A quick trigger test is to swap the trigger wires from 2 and 3 cyls. if the problem moves the trouble is the trigger if it stays on the same cyl. you have a bad switch box. To test the coil swap input wires on 2 and 3 and see if the problem moves if not is the coil or wiring
