Question about Cars & Trucks
The radio quit then the next day the battery went dead I changed alternator with two different new ones They start out with an output of about 14 volts but drop voltage after running awhile
Have you considered the ignition switch or is that
why you want the wiring diagrams, to see if it supplies
the generator/alt control to the field in alt
We have no info etc,sorry, just use the site as you do
I see where folks say you can register for free on auto zone
site & have access to whatever,try that
Last resort you have a repair shop print what you need
from Alldata that is owned by auto zone

SOURCE: Alternator or Voltage regulator
if you can carefully put a metal wrench on the rotating pulley of the alternator and felt a magnetism attracting the metal wrench, then your alternator is charging. if there is no magnetism, then the alternator is not charging...
another test is to measure the voltage on the small wires that went in to the alternator that says "F" for field, it should measure battery voltage...that is the voltage from the regulator..that means your regulator is working...but the altrntor is not..
without that battery voltage, then the regulator is he culprit...
pls be carefull...
hope i was able to solve ur problem..
pls rate me.. tnx, drcool..

As dumb as this may sound check the termials and if the u-shape is up then flip it over. I had the same thing happen to me on mine and now it works fine.

SOURCE: alternator not charging
ALTERNATOR DRIVE BELT SLIPPING OR BATTERY CABLES NEED REPLACING IF THEY ARE THE ORIGINAL ONES.THE VOLT GAUGE COULD BE FAULTY.TO TELL GET A DIGITAL VOLTMETER HOOK TO CAR BATTERY CRANK CAR UP.BATTERY VOLTAGE SHOULD BE 13.5 TO 14.5 VOLTS. WITH NEW CABLES. IF NOT CHECK ALTERNATOR FIELD WIRES FOR DAMAGE ALSO ALTERNATOR POSITIVE WIRE FOR DAMAGE.

SOURCE: how to connect a new
knowing the color codes can be a great help..usually in 12v reg system,from the regulator there are 6 white wire having a stripe codes,blue means neutral,green means field,black means ground to body,white means hot wired to +12v,yellow means to bat charging indicator going to instrument panel and finally red means to ignition....and always secure the regulators case to ground.
