This is where I become your bestus buddy!
We're gonna test the coil with the help of morris
I have the "1979" paper manual that was left in my '79 cj 5, by mistake when I bought it in 1983.I did not take care of it, when I realized it's value, I started treating it like it was a sacred scroll
Using the drop-downs, install: cj 7
. Then 1980 (76-78 ign is different than yours [prestolite].79-80 is the same as yours [motorcraft])
They did not replicate the manuals, so "1980" is gonna be you, when you look stuff up!
Now then, last thing."Power plant-ignition system (1,961kb)". You have just entered "the book"!
Scroll a bit
(these pages can be printed)
You will run into diagnostic chartsthey are like flow charts
The "specs" you need for the tests. Are further on. On page "1g-18"
They also assume that your "mechanicals" are in order when you begin.(Stuff I was trying to pull out of you. Like distributor in right, timing gears right? Modifications other than factory?). That stuff is found in here too, you just gotta have a librarian (me) guide you to them, at the right times!
Forget trying to test the module yourself, you can't do it all--at once, as fast as the parts store tester can over and over, you will be fooled by the test in the manual
In fact, you'd be better off buying one---if it was not the problem, you would have a spare
I keep a spare coil, ignition module, and a fuel pump in my console. So far, 2 other cjs were glad. One needed a fuel pump, the other an ignition module!
I have added lots of storage---made lots of stuff "user friendlier" (like roller and spherical plane bearings incorporated into my clutch linkages (never have another linkage problem again!). Many other things too!)----I pretty much carry a condensed tool shed w/ me.I can show you a lot of this, if you are interested
Last two pics----me just prior to ranger school w/ my '79 (#2 of 7 cjs). My mannequin on patrol in my present day man-cave
Keep me posted---i really hope I have not been replaced by a book!
