Earlier than the Zipstart rusty ute.
Well the sad news is that the aftermarket coil did not work. It fits perfectly and looks pretty much the same as the old one, but it will not work. I got a strange result with the spark lead firing sporadically, then not at all for some time, then firing again. It was all over the place. Weak spark one turn, strong spark next couple of turns, then nothing. Coil I tried is supposed to suit MA05183A, MA05529.
So I put the old coil back and now it sparks strong and consistently. Old coil tests at 6.3. The problem is probably as a member told me on another thread, it has something to do with the way the coil is wired, as well as the thickness of the wire and number of winds etc.
With the old coil testing at just 6.3, I can still get a very good spark with electronic ignition.
This was in fact the coil I trialed. It would not work properly for me.
