1982 CJ8 six cylinder spark problem

Re: 1982 CJ8 six cylinder spark problem
Fixed-at least for the past two weeks. Have driven it daily.
What a saga I went through; still not sure what was wrong or what
fixed it exactly?! To do a summary recap of it all in the order it
finally happened as best I remember it (and I'm probably forgetting
something).
1: Replaced plugs and plug wires
2: Replaced distributor rotor and cap
3: Replaced coil
4: Replaced plug wires with better ones
5: Replaced distribtor rotor and cap again.
6: Checked and rechecked all connections
6: Replaced the ignition control module
7: Replaced the distributor
8: Checked to make sure good grounds everywhere I could with jumper
cables.
9: Checked volts throughout at relevant locations and found them, I
think, within spec
10: Retryed a lot of the above, checking all connectors very carefully
*** Nothing seemed to have any effect motor would barely run ***
11: On a whim and because we didn't know what else to do -- took the
connector to the coil loose and placed it back on the old coil, with
the old coil just laying loose. IT FIXED THE PROBLEM!
12: Placed the connector back on the new coil which remained bolted to
the engine block-- IT CONTINUES TO WORK.
(Examined this coil connector VERY carefully -- see nothing out of
order.)
Set timing -- and have been driving it for almost two weeks.
So what happened; I don't know, and I'm keeping my fingers crossed.
Thanks to all of you for your suggestions ......

Re: 1982 CJ8 six cylinder spark problem
The coil power wires can get brittle and start to pull apart. Pushing
the clip back on might have shoved enough strands of copper back
together to allow a decent spark.
Just a wild assed guess, but it happened to me out in the bush on New
Years. It started losing power then up and quit on me.
I went looking around then noticed a crack in the insulation going to
the coil negative connection. Sure enough only one copper strand
holding that let go as soon as I touched it.

the clip back on might have shoved enough strands of copper back
together to allow a decent spark.
Just a wild assed guess, but it happened to me out in the bush on New
Years. It started losing power then up and quit on me.
I went looking around then noticed a crack in the insulation going to
the coil negative connection. Sure enough only one copper strand
holding that let go as soon as I touched it.

Re: 1982 CJ8 six cylinder spark problem
Mike,
That's what logic would seem to say, that there is some problem with
this clip/these connections. But try as hard as I can, I couldn't
observe anything bad at all; nor could I make it fail.
I'll keep watching and messing and see what happens and let you know
if I come up with anything. (If it does turn out to be that, I
replaced a lot of parts unnecessarily. Of course, now I've got some
good old spare stuff.)
And thanks to you guys I've learned some things.
I've driven the Scrambler more the last two weeks, probably, than I
did all of last year. Plan to keep driving it as my daily driver for
a while so we shall see.
Thanks ..... Mike
