I've got a few questions regarding this type of ignition coil. I purchased one from a dealer to replace the points, condenser, and old coil on my 1979 Simplicity Sovereign 7116.
Since install, it always started hard, and by hard i mean lots of turning over before it fired. When it did start, it ran pretty good. Seemed a little low on power, but I could cut lawn and till with it. As of late, it's been getting harder and harder to start. To the point where I give up.
Here's everything I did.
Replaced old coil with new Magnatron coil.
I think the kill switch wire was hooked up properly as turning the key off would kill the engine.
Tested for spark by removing spark plug and grounding to a head fin. Very small spark, if any. It seemed that some engine revolutions did not even produce a spark.
Screwed in spark plug and tried to start...no dice.
Tested for spark again, nothing at all.
Tested plug on my Ariens GT18 (automotive coil type iginition), grounded to frame and had great spark.
Removed kill wire from terminal on new coil and tested for spark on the Simplicity again...nothing.
Is the coil bad? Magnet on flywheel holds a screwdriver out straight, so I think the magnet is fine.
If the coil is bad, and I purchase a new one, how exactly should I hook up the kill wire?
Currently, there's a wire coming from the key switch down to a small plastic tab on the points cover. Then another wire (on the same termial) going up to the kill switch connector that plugs into the coil. There's a second wire in that kill switch connector that I have grounded to the engine.
Sorry for the long post...from everything I read, this Magnatron coil is supposed to be pretty dependable and produce better spark than points and condenser.
Thanks in advance.
