Why is my alternator not charging on my 1997 Honda Passport after I put a new one on?

Answer 1

ANSWER 1 - April 5, 2008 I have a 1997 Isuzu Rodeo which has the same engine as your Passport, assuming you have a 3.2L V6. I have had the same problem as you, putting 3 different remanufactured alternators on with no success. I finally went to an auto electric shop and got an new alternator (vs. remanufactured) and it fixed the problem, all to the tune of $514.00 for labor and the alternator! Remanufactured alternators have bad voltage regulators in them. On the Rodeo and Passport, the voltage regulators are grounded to the Engine Control Module. The Heater/AC blower is also grounded here also, so when the alternator is not charging, the blower doesn't work. On the right side of this type of alternator, there is a plug connection. The alternator has the "male" terminals, while the "female" terminals are from the vehicles electrical system. One of the "male" terminals, known as the "C" terminal, connects the voltage regulator to the ECM (engine control module). As stated previously, in remanufactured alternators, the voltage regulators appear to be faulty, a problem that has been in exsistence since the 1980's, whereas the voltage regulators do not emit the proper voltage. While I did get all of the remanufactured alternators from Advance Auto Parts, they obviously to not remanufacture them, so it is not really Advance Auto Parts blame, however I wonder why they continue to sell them, as a recall has been previously issued regarding this problem. I am confident that if you replace your alternator with a completely new one, not remanufactured, and your problems should cease to exsist! In addition to the above, obviously you should disconnect your battery prior to doing anything, check the tension of your belts(s), and make sure your battery is ok. I hope this helps you and everyone else with this problem!!! ******************************************************************** ANSWER 2 How old is your battery? Check all of your connections. It they're all OK, drive (if it's drivable) to an auto parts store and have them test your alternator. If the alternator tests OK, have them test the starter. Chances are, one of those items are the culprit.
