From local parts store, I was sold an AC Delco reman alternator for a 85 cj7 6cyl 258. The part number is 334-2112 and is 63 amps. I researched part number and found that it is for a 80-82 cj. Part number 334-2114 is for the 85 cj7. It is also 63 amps. The 334-2112 Alternator I was sold is not putting out proper voltage. I checked all wires and cables. Could this wrong part be the problem.
