Motor had no fire at all. I had the motor running a couple months ago then decided to quit messing with it until the weather warmed up. Went out to crank it this weekend and no spark. The motor is a 1990 Johnson 60hp but it does have the ignition system off a 93 60ho on it which is slightly different since it had quick start. Anyway I feel pretty confident the stator is bad since it has some cracks in the outter shell. I also suspect the timer base. I checked resistance on the stator and timer base this afternoon. Here are the numbers. For reference I was using a Fluke 87V true rms meter.

Timer Base:
W-G: 15m ohms
W-P: 5.5m ohms
W-Bl: 22m ohms
W-BW: 0.67k ohms

Stator:
Br-BY: 0.829k ohms
O-OB: 406 ohms

Any ideas? Also is there anything else I should check?

Anybody got any ideas? I went ahead and ordered a stator today since it has some cracks and the one side appears to be open.

Just to clear up any confusion with my shorthand, these are the resistance readings I got while checking the stator and the timer base.

Timer Base:
White to Green: 15m ohms
White to Purple: 5.5m ohms
White to Blue: 22m ohms
White to Black White: 0.67k ohms

Stator:
Brown to Brown Yellow: 0.829k ohms
Orange to Orange Black: 406 ohms

New state didn't fix it. My stator had cracks in it so it needed to be replaced anyway. I'm leaning towards the timer base since the ohm readings are way off. I've disconnected the black yellow wire, the yellow rectifier wires and even the main harness (red plug). Anything else I could try before I drop the cash on a new timer base?
