Alternator Issue

92 4.0.............when i turn the ignition key to on the alt gauge reads 1/4 when i start the engine i does not move. it always went to 1/2 before.
i have the squealing belt thread so i think this might be the issue.

when i had the belt off i turned the pulley, felt OK but i don't know what OK is. did not feel like the bearings were bad. I can say that if i gave it a fast twist it would stop turning immediately. I hate to just start trowing parts at this.

Don't rely on that gauge. Take it to the autoparts store and have it tested (or buy the gauge if you are so inclined and find the thread on how to do it). It could be the battery, alternator, bad cables or connections (most likely), or just a bad gauge. If you are going to throw parts at it, the first should be new battery cables.

You're right. Don't throw parts at it, throw a volt/ohm meter at it. What voltage is it putting out?

The great uniting factor is that we are all jeepers at heart and are willing to help each other out even if its just a little. That's what the jeep wave is all about: community. The wave is the tip of the iceberg.

Just had my alternator seize up on me, and the belt was squeaking like crazy just before. I do think your alternator should keep spinning when you give it a fast twist though. Not so much as say, your water pump or power steering, but I don't think it should stop immediately.

Most auto parts stores can test it if you bring it in, or, like others have suggested, find the thread and learn how to do it!
