First does this truck have external voltage regulator? I installed two junk yard alternators think I have went over checked and cleaned all grounds and connections yet still average 12.11 - 12.86 volts out of alternator testing with red lead on big wire and black on alternator housing. Also got battery voltage out of one small field terminal and a sporadic reading on other small terminal but nothing close to the other side could the regulator be bad or do you think I have ended up with two bad alternator's and two bad batteries? I have noticed the battery loosing some power while sitting but while testing I made sure it was reading 12.6 volts. I would also get the 12.6 out of alternator, but never higher than battery voltage also showing codes 41 and 32. I cleaned EGR and installed another diagram.

The voltage regulator is incorporated into the Engine Control Module on all fuel injected Chrysler products.

code 41. Alternator field circuit. An open or shorted condition detected in the alternator field control circuit.
