found problem... was a cracked ring connector on ground from alternator to engine block. a very fine crack at base of ring was causing intermittent charging. additional problem was a faulty NEW alternator, it had a factory defect on rectifier. Thanks for all of the help. The circuit schematics...
gonna get a check on the NEW alternator just to make sure. charging was intermittent, but now no charge at all. when i put new alt in it was charging fine then, nothing after a while.
the voltage is the same running as pre-ignition, only drops when revving up or accessories turned on. definitely running off of battery only. there is a batt temp sensor, looks fairly clean and wires are securely connected.
i found the fl, but really couldnt tell if bad. i assume its good because i can measure the battery voltage on it.
Is there anyway to install a voltage regulator work-around?????
Hello All, Have a 1998 Cherokee 4.0, need help with problem:
Alternator is not send charge to battery, was intermittent now no charge at all.
1. Replaced battery
2. Replaced Alternator
(even though they both tested good)

Does anyone have a schematic for which harness...
