'77 CJ5 Jeep w/electronic ignition problem
Maybe someone here can help me figure this out. I have a 1977 CJ5
straight-six jeep with electronic ignition and I'm getting no spark
from the coil. I'm guessing it's the electronics module, but I'd like
to try to confirm this before buying a new one.
It was running before and suddenly wouldn't start. I've replaced the
distributor cap, the battery, and the plugs. And I know it's getting
gas.
If anyone has any ideas on how to test the module, or other ways I
might narrow down the cause, I'd be most appreciative.
Thanks a lot,
*****

*****, i have a 75 CJ-5, this was the 1st yr., with the AMC. BID ignition
system, do not know what the last yr. was...but AMC issued a recall on the
ignition system...bottom line...cut off the electrical connectors, leaving the
wires as long as possible..solder the wires, color to color as they came off
the connectors, tape w/electrical tape, etc. This should be done with both
connectors, i.e.2-wire from distributor, and the 3-wires from the coil...hope

Re: '77 CJ5 Jeep w/electronic ignition problem
How is the ground strap from the back of the engine to the firewall? If
it is rotten, the ignition can lose power.
You could test that with a booster cable. Run it from the battery
negative to the firewall or right to the ignition module to see if you
get spark.
A bad connection on the starter solenoid can also affect spark for
starting. The small side post powers the coil when the starter is
turning.
Then those power plugs on the coil itself go bad real easy too. I would
have a look at the connections.

Thanks Gene, for responding. But I'm not quite sure I follow you. Is
it that the connectors potentially faulty, so I should remove them
from the circuit?
Thanks,
