Re: Ignition Noise in AM Radio in 1980 CJ-5 Jeep ??
Well, it is a bit hard to believe that my "tuner is shot", given the fact
that it picks up am crystal-clear WHEN THE ENGINE ISN'T RUNNING and
causing the strong ignition noise.
Thanks for the other remarks, I am suspecting ignition noise such as plugs
/ plug wires/ etc etc.
--James---
---------------------------------
If it works fine in FM and not AM, the tuner is prolly shot...is it a
stock unit, ot aftermaeket...swap it with another
(wifes/friends/whoever) and see how it works then...

I would first double check to make sure the antenna wire connector is
shoved all the way into the back of the radio. If the shield portion
of the mororola connector has slipped out it will pick up ignition
noise quite efficiently.
If you have checked to make sure that all the plug wires are seated
correctly, and your engine block grounds are all good, it might be
time to replace the ignition wires, plugs, distributor cap, and rotor.
Not sure if that vintage system uses points or not! I haven't had a
car that had points since I sold my 69 V6 CJ5.
Anyway, I have done a lot of work on ignition noise suppression in my
jeep to accomodate my radio gear and have found that the usual
replacement ignition wires from places like Autozone are not up to the
task as far as suppressing noise. I ended up buying a set of magnecor
wires and ended my noise problems 100%. They work great and look
pretty too! They are not carbon resistive, they use a ferrite core
with an inductively wound conductor over the ferrite. Stops RFI in
its tracks, and as a bonus, they do not break down over time as carbon
wires do. A pre-cut set for my 4.0 liter engine ran around $65.

Re: Ignition Noise in AM Radio in 1980 CJ-5 Jeep ??
Make sure you're not running low or no-resistance spark plugs or ignition
wires. Those will cause a HUGE amount of noise to be generated that an AM
radio easily picks up. Use only resistor-style spark plugs and
carbon-impregnated resistor type (RFI suppression) ignition wiring.
"Performance" ignition wiring and non-resistor type spark plugs are
responsible for 99.9999% of all the kind of noise your AM radio is picking
up.
