jeep pcm bypass for "real" alternator
hey, ive got a 95 wrangler with a charging problem. i swapped out the
alt but no good. i took the new alt out and had it tested and it
tested fine.. i then checked all the charging wires and fuses and
lights.. the check engine bulb was missing (how odd *sarcasm) i put a
new one in and guess what?? the check engine light came on!! well
great. i did key turn thing and it flashed a 41. the field circuit
generator code... i check the continuity on the wires the manual
indicates.. they are fine. great now im thinking i need a pcm.
i asked around and someone said i could bypass the pcm and hook up an
older voltage regulator out of an old pick up (i got new one for a 77
ram charger) my problem is i dont quite now how to do this... im
not real knowledgeable about electronics but im a fast leaner.. would
anyone mind giving me a rundown on what wires go where? do i need
to take the alt apart? am i going about this the wrong way, would it
be easier to fix the problem another way.. any help would be
great oh and im not worried about the check engine light staying
on we dont have smog checks here.. thnx again jay

thnx i'll try this and see if i can get a little closer to fixing the
problem finding an open circuit would be nice

I think the deal is to install one of those "one wire" alternators and
live with the Check Engine light. Seems the regulator is built into
the PCM on that model(same one I have). I got lucky and it was just
the brushes on mine.
