hey...umm when u install u alternator....you didnt have any problems making the alternator to charge...cuz i have the same style jeep...mine is a 94 but when i got my mechman alty l couldnt make it charge... i have like a black module box tht goes to the back of the stock alty but when i got the mechman alty it came with the plug with two wires..but didnt knw where to hook them up..because the stock alternator only has the one wire charging cable...so i called mechman and he told me to rewire direct to an on off switch 12volts....so i did tht and it charge but my vltage would fluctuate and then sometimes my voltages would be all the way down and stay like tht...and well my friend told me maybe i needed a external regulator...i just want to figure it out because i took the alty off been sitting in my closet for like 4 months now...idk if u can give me some advice wht it could be since i see u have two alty and an external regulator and its a jeep lol... would appreciate it
