My alternator went out on my 1999 jeep cherokee sport 2wd 4.0 v6 . My alternator went out . I was told it would cost 149.99 for a new one. A few years ago I bought a motor and transmission for my jeep . I thought it was the exact motor and trasmission I have in my truck so i decided to take the alternator off and save some money but there was a problem. My alternator only has 2 plugs . This motor has a alternator that is different it has a small plug and a big plug with one big wire and two small wires . I really dont know how to explain it other then the pics. My question is can and how do I convert the alternator to work in my truck. Also the one on the top came out of my truck . the on eon the bottom came from my spair motor. I want to convert the one on t

 

That's an older alternator it can be wired in both have the same amount of wires and they just hook up different but the wires do the same think .

 

thanks tech i think i found a video on youtube about it but i just went ahead and ordered a new alternator. i have had one car catch on fire on me in my lifetime and thats enough for me

 

I'm getting ready to install the larger 160amp alternator in my XJ along with the cables .

 

ok i would like to save 150 dollars. if you post a viideo of the conversion or find one that shows me how to do it . i will go for it !

 

Here is a video I found
Hope this helps

 

Thanks tech . this loks like a good one. Listen I have a 1999 jeep cheokee xj 6 cylinder 2wd 4.0 sport . i bought a spair motor and transmission . has 98 on the casting and transmission . would that be an easy swap if i ever needed to ?

 

I would look at the head and see if they are the same casting number because the intake and exhaust mite not fit , the ports could be different .

 

ok thanks do you feel it could be modified if it cant ?

 

I think you can use the intake and exhaust it came with if you have them . Checking on Rockauto it does use a different intake/exhaust gasket so one or both of the manifolds will be different .

 

thanks
