Going through an H4 which just plain quit in the field. When checking it, no spark, and no impulse coupling sound.
Impulse coupling wouldn't be a problem while running, tho'. It was balky to start.
Also, checked the coil which had an open secondary winding.
Points were good, condenser checked out ok, ohm meter showed changing readings.
I think I've read every blog post here and elsewhere, and studied the Blue Ribbon manual, etc.
Disassembled it, and replaced the pawl springs which were pretty sad. One broke.
New coil, good readings on the primary and secondary. THE CURE!
New points at .013"
New condenser with good ohm meter readings.
Checked the Coil cover, perfect continuity from contact strip to coil wire.
Internal wiring looks good, no shorting indications.
So, setup in a vice, no cap or rotor, and a ground wire from the body of the mag to a new spark plug and wire. Perfect continuity. The plug wire is in the coil cover.
Don't you think by turning the coupling and getting the 'snap' I would get a spark? Can you find any flaws in this setup? I know I'm omitting the cap and rotor, but the coil should put out a jolt without that.
So, what next? I think I should have gotten a rebuilt, considering the cost and time so far.
Thanks, guys, I know it's something I'm overlooking.....
