Re: Battery, Alternator or Regulator problem '64 Sport Fury

[Don Dulmage <big-d@xxxxxxxxxxxx>]

All testing should be done with a voltmeter. Charging systwms with 
alternators are so simole , that is what cnfuses one. Check voltage at rest 
engine of. Start car and run at about 1500 rpm Does the voltage rise ? If it 
does it is charging. if not it isnt. Now for the 64 dollar question . Is it 
the regulator or the Alternator. to find out we need to remove the regulator 
fromthe system or by passs it. WIth a single wire alternator  remove the 
small wire (unplug) from the field terminal (Only one on a one wire so no 
chance of maiking an mistake) Run a jumper from the big alternator terminal 
to this small one. Satt the carand repaet the 1500 RP test for just s hort 
ime. Does the ALternator work now? if yes it is Ok and the regulator  is 
kaput. Replace the eregulator.  If NO then it is the alternaltor. If it is 
the altenaoptor and it is mopar itis most likely only brushes and nothing 
else goes wrong with these good ol bruts. Replace and repeat the test.  With 
tow wire alternaotr it is abit easier . REmove bth plug in wires . Turn the 
ignition to on. Using a test light find which of those smal wires has power. 
Plug that wire back on the alternator  using a jumper ground the other 
alternator tern mnla to the alternator cae. leaving the other small termnal 
umplug. Start the car, do the 1500 test  and seee if voltage is rising. If 
yes same as before Alt is good. if no Relacve brusces and start again. If 
yes then regulator is kaput.  Do not replace both . That is just a waste of 
money. Just do this test exactly as described . It works and it is fool 
prrof. The amps of an alternator are controlled by its windings. The 
regulator controls the voltage so that is why we test c voltage to find out 
of it is functioning. The dash gauge is a decoration. Pay little attention 
to it whatever unless it is on the discharge side.
Dont try to rationalize when you are doing these tests. Just do them . They 
work. Five minute should beal that is necessary to dianose any of out Mopars 
alternator systems.  Ok 10 your fisrt time.
