O.K. this is the problem im having i switched over from serpentine to v-belt sytem for about the firts 3 months or so it was charging fine, but then one night on the way home it quit charging so i changed the alt. to a different one that i know was charging on another vehicle but it still wouldnt charge, tried a brand new alternator and still nothing. even checked the wires going to and from the alternator everything seems fine. what could it be if anyone can help me that would be extremely kewl. thank you,
thomas

 

is this the wrong place to put this or something or does nobody know about what could be causing it?

 

Have you checked the fusible link on the starter solenoid that goes to the alternator?

 

didnt even realize there was one on there. and thankyou for responding this is driving me nuts.

 

No problem, glad to help.

 

you changed the alt a few times, what about the battery? batteries do eventually lose their ability to hold the charge (or sometimes ya just have to add some water)

double check the wiring going from the alt to the batt, make sure it hasnt been hacked up at all and improperly put back together

 

i just brought a brand new battery and still the same problem but wednesday im gonna check that fuse link going to starter id be willing to bet that was what is causing me my problems. and ty also for replying.

 

Rarely do the fuse links fail, the tie point should be at the starter. Perhaps corrosion occurred down there. Another thing to look for is the fuse panel top right for a fuse labeled "chg/fan". That line turns the alt on and off. 89 should have a 2 wire top plug and the rear lug. Rear lug should read with a voltmeter the same as the battery, the top plug will have one heavier guage red (usually) wire that should also read battery voltage. The brown/tan wire is key controlled voltage slightly lower than battery which is called the "sense" wire. It monitors voltage in the interior harness and turns the alt up or down according to electrical demand.

 

i checked the fuse today and damned if it wasnt blown i replaced it and hehe it started charging this has been a pain for me a long time. i cant believe it was only a fuse. thanx again, thomas
