I came to a stop sign and rolled off the brake, when I started to push down on the throttle it seemed to bog and the speedo jumped to about 100 then came back down and was fine after that. When I started to park it surged a couple of times to about 60 but didnt feel the Jeep bog at all. Has any one ever experiance something like this? Any info will be greatly appreciated. By the way this happened to my 01 XJ.

 

I guess nobody has had this problem. Well I hope its not a big deal and it wont do it again.

 

Wouldnt sweat it. Rigs have hiccups. Mine just died one day. Never happened again.

 

I took it for a drive a few minutes ago and mi check gauges light came on, mi alt gague was all the way down so I guess mi alternator is shot. I wont be able to check it till it stops raining

 

K. Now sweat it. Keep checkin the forum for great advice! I would have that alt checked again. Could be wiring between batt and alt? Def check the wiring, grounding issues mentioned. Keep us posted.

 

Any one know if the alternator on the 01 XJ has an external regulator? Cause I found a 136amp alternator for a V8 GC at my local Oreilly that they actually have in stock, but it has an external regulator.

 

The regulator is built into the PCM, so yeah, it is an external regulated alternator. Your funky alternator is also causing the speedo problem you're having, low voltage will cause all kinds of weirdness to happen. That 136 GC alternator may require some slight modification in order to mount up to your XJ.

 

I'm willing to do a lil modifying. I would imagine the mod needed is a lil grinding to the new alt? Is it worth the extra 12 amps and will I need to upgrade my wiring? Cause my stock alt is 124 amp.

 

Your speedo goes to 100? hahaha mine only goes to 85!

 

Yeah, its an 01.

 

Mines a '94 I Love cherokees!

 

In my opinion it's not worth the trouble for a 12amp increase, but the wiring is the same between the XJ and ZJ V8 alternators from 93-2001.

 

Thanks for the reply. I guess if I decide to go with the GC alternator I'll just get one from the JY and have it rebuilt

 

Update. I went ahead and bought an alternator from Oreiley and the Jeep is running once again(I will drive it to work tomorrow and see how it goes).
