Hmmm...found fusible links you spoke of, but how are they accessed to see if they need replacing? The black "rubber housing" around fuses looks like they need to be cut open to view. Thank you for the suggestion, I had not known about this possibility.
I did not have the "cut" the fusible link to get it out, on my 90 4.2 when it blew.
I did however need to clean it find where it opened and pop off the cover and replace the fuse. Sorry i cant explain it well or give you more info. This was.....6...7 years ago. I looked on google for a pic but came up empty.
To check a fusible link, pull on it in increments and see if it stretches. If it stretches, you found the blown link.
Did you check all the bulbs? 12 volt alternators can put out up to 20 volts unregulated. Thats enough to blow all bulbs.
Thank you all. I will perform this test next chance I can get to it. Ironically, this morning I go to take daughter to school and Jeep won't fire up. I went to last place I worked on and jiggled the starter fusible link wire and it fired right up. I know now where my problem area is. My next question is: how do I replace these fusible links, and is it a complete wire assembly, or do I simply replace inline fuse? I am new to this repair and remain clueless.
You all have been a tremendous help! I love this place!
Anytime K4. Your test for finding a failed fusible link worked. I found the damaged fuse immediately after performing the test.
It was definitely a team effort and this forum gets all the credit. Thanks again to everyone.
I plan on visiting this site a while. I am in the process of reviving my old '89 back to par after I almost sold her for $700. What a mistake that would've been!
See you around!
