A new poster here with a problem looking for help, so appreciate the help.
Weird is the only way I can describe this. Here is the history..
About 3 weeks ago while driving, alternator gauge pegged out at 19 volts for 10 seconds and went away. First sign of gremlins in the jeep , went away , everything was fine
About two weeks ago, had trouble starting it. I had to put foot on gas pedal, got it start but it would not idle. While on the way home, the idle returned to normal and no issue.
I was figuring it was a matter of time before the jeep would break down on me. Well today she would not start.
Turn key, Absolutely nothing it was making not attempt to start. Gauges would jump around a bit. Lights would not come on, the horn barely blew. Jeep would not jump or could not push and pop cluctch.
Battery had 12.8 volts, so I figured it had to be something with power to start rely. I had 12.5 volts on one of the relay poles and no volts on other poles as expected. When key was turned, the 12 volts dropped to 4 and the pole with none had 3 volts. I figured it has to be the ignition switch. I changed it out but still had same results.
Battery was two years old, decided to get it tested at autozone and it tested good. They swapped it for free, so I took it and went home put it in.
Jeep started immediately, lights worked horn blew!! I left it running while I picked up my tools probably 10 minutes. Since I had to put my steering wheel together from changing ignition switch, I put her in the garage. Once in the garage, shut her off, then tried to restart NOTHING! DEAD, no horn no lights, check battery 12.6 volts.
So I am lost. I was going to pull the alternator to go get check next but not sure if that is the next step , since it would not jump and I only got one start on the new battery.
Any suggestions on what should be next? can you get the computer tested?
Appreciate any suggestions
