Ok guys so I’ve posted a couple different threads here pertaining to my 1991 4.0 jeep xj. My first issue was not getting spark. Found that the problem was a faulty pcm. During the process though I replaced a boat load of part. Starter, alternator, battery, spark plugs and wires, coil, distributor, and also pcm. Finally got it all started and was running fine for about 40 miles. Then noticed a check engine light came one and my battery voltage was way low. The check codes it threw were 34,41,21 and 62. I figured out the 34 code (map sensors vavcuum hose was clogged. 62 says it’s not reading my odometer and the 41 is the alternator is not charging the battery but as I stated before it’s brand new. So I have no idea what my problem is. The pcm is an A1 Cardone which I ordered online. I didn’t have the original serial sticker number from the old one because there was no sticker on it. So I put in online the type of vehicle I had assuming it would be the correct one. Everything was working fine except now I’m getting this 41 code and the alternator is not charging. What in the holy hell is going on?
