I have a 2000 Jeep Cherokee with about 3 inches of lift. 155,000 miles. I got up this morning it started fine now my driving to work the battery gauge went all the way down tonight. Anybody have any idea what this might be?

 

Also my power steering Pump is going out. I do not know if that has anything to do with it or not.

 

This is a OEM question not Advanced tech.

Sorry.

 

did both problems appear at about the same time?
could be a belt,ie. belt slipping on the p/s pump and alt. pulleys,would of course, cause a loss of performance in both.
OR,,
you could have your local-friendly auto parts store do a load check on your charging system, they do it for free, and check the fluid level in your p/s pump.

 

No the power steering pump and been a pain for about a week or so. The other day I got in it and turned the key and it was like the battery what either dead or unhooked. I rolled it back to jump it and than the light just came on started right up. I had the parts store check the battery and it was at 51% he said normally if the battery was bad than it would show something like 10% and he could not check the alternator unless the battery was 100%. I am thinking it is just the alternator.

 

Some regular maintenance you should do anyway now and then. Make sure the belt is tight. (for me the alt is the first thing that slips).

 

Ok... Took your advise and it worked. I tightened it up and it's working fine. Still got power steering issues tho.

 

Can you get it over tight? I was driving yesterday and now the battery gauge went all the way up to max! 19 or what ever it is. Anybody got a clue?

 

Get your alternator tested, If it passes than you need a new voltage regulator(IE. Whole PCM)

Either way your alternator should not be throwing that voltage.

 

I will tomorrow. Where Is that regulator?

 

Regulator is in the computer, have to replace whole pcm.

 

Gee! Hope it's cheaper than an alternator.

 

Son of a gun just looked them up on eBay! $100-170! I am junk yarding!!! Soooooo excited! Lol!

 

Give her a good run and see where you are with the belt tight. 19v is to high of course..maybe something askew? As mentioned I think the regulator is in the PCM, not the Alt. Just a little .o2
