Then I drove it and it drove pretty well. Some tiny pop pop, but other than that, like a champ. Then I took it out tonight, and it drove terrible!!! When I got back home I turned my head lights out and the engine picked up and no pop pop. Then I turned them back on and 1 pop. Then off, nothing. Then on, 1 pop.
[/ QUOTE ]1. OK, now sit down and think!
2. You've done a lot of work on that Jeep, and it's helped,
3. However, the symptom you describe is directly related to voltage.
4. Voltage is the life blood of the ignition system.
5. Try driving a Jeep with a constant loss system... or the alternator ain't chargin'.
6. You'll do fine as long as the voltage is above about 11 volts.
7. The second the voltage drops below about 10.8 volts, all hell breaks loose.
8. No you turn on the lights, and guess what's happening?
9. I'd almost bet the voltage is dropping... but why?
10. Well, it could be the dimmer switch is bad, corroded,
11. It could be the light switch is bad, corroded,
13. You've got to check those items out to rule them out as a problem.
14. You've got to rule out the grounds because current returns via the ground.
15. If the grounds are corroded you'll get lots of strange problems.
16. So, again I'm gonna say:
a. Check your grounds.
b. Check the quality of the headlight swtich,
c. Check the quality of the dimmer swtich/connector,
d. Check the quality of the headlight wiring and connectors.
17. Make sure the symptoms are repeatable by turning on the headlights,
18. If they are you've found a very important clue.
