I upgraded my RENIX Cherokee INTERNALLY REGULATED to a 120amp zj EXTERNALLY REGULATED. my issue is OVERCHARGING!!
VR125 chrysler voltage regulator.
96 zj alternator
All new 4 gage wire.

VR hooked up to ING in the fuse panel to the same wire that goes to the battery and to the positive of the alternator. Neg is from VR to alternator and to ground. ( block ) and from the positive battery post to an ANL 150 amp fuse straight to the alternator battery post.
I have disconnected the VR and i get 11v from the alt at the battery and sounds good. Hook everything up and i charge at 14.3 at ideal give it gas and i here a loud squeal from the alt and it shoots up to 18v. Tried everything i can think of and googled a sh"t ton. No real luck with RENIX everything is 91 and new...

Please any help will be greatly appreciated.

Thanks

Jason

i dunno about that regulator... i have a 96 alternator in my renix MJ... only because i have a 96 XJ with a lifetime warrantied alt

I used this link to help me through it... http://www.cherokeetech.com/VBull/sh...grade-problem&

I used the ford truck regulator... and this to buy the regulator... http://www.ebay.com/itm/Chrysler-Dodge-Plymouth-External-Voltage-Regulator-/230375680398?hash=item35a375e98e&item=230375680398&pt=Motors_Car_Truck_Parts_Accessories&vxp=mtr#ht_3223wt_234
See if all that lines up the same as what you got...

Same VR that I have. I read the links that you gave me the pics have been removed to show how he hooked it up. Everything that I have seen has been correct. Did you have to cut the plug from the old alterantor? when you did your upgrade? did you remove the wire fromt he alternator to that fuse box looking thing? I took mine off and rean straight wire with a anl fuse instead. do you think that would make a difference?

REally come on RENIX guys. Nobody has done this upgrade?

I want to see pics on how you hooked it up?

id take pics but im in afghan... all i did was cut the plug off that went to the alt and spliced on new wire from that to the regulator... was easy peezy!

jaythenewguytojeepn

Afghan? Severing for our country?

jaythenewguytojeepn

Oooo u spliced the wires from the plug to the VR? That could b what iam doing wrong...the plug is there and i ran new wire.

Lol..i Sault you sir. I work next to a military air and they fly those all day long. Thats a really cool job.

I didnt even think if that. I figured that everything else was new..lol..ok i will figure out what wire goes were. Thanks for the extra insight on this ive been beating my head against the wall. Hope this is the fix i need. I bought a ford truck VR. The VR 730

Ok it worked. Thank you. Hey now my volt gage in the jeep dont work. Did i miss something or do i have to do a external? Does your still work? Did you hook up both wires or just the one

huntingman2706217

i think i used both wires... the regulator is case ground... glad you can at least drive it! mine works though!

jaythenewguytojeepn

Did u hook them both up together or to a different letter on the reg? If u can remember that would b great

huntingman2706217

i dont remember man... wish i was home and could tell ya... i know i went by that think so whatever they did probly... i KNOW i have two wires going to TWO pins on the VR though... i just dont remember if two wires went to ONE of the two plugs... lol

jaythenewguytojeepn
