Alternator Output Wire Resistance Test
Fig. 1 Alternator output wire resistance test (Typical)
Disconnect battery ground cable.
Disconnect "Bat" lead at alternator output terminal.
Connect a 0-150 amp D.C. ammeter in series between alternator "Bat" terminal and disconnected "Bat" lead wire.
Connect positive lead wire of a suitable voltmeter to disconnected "Bat" lead wire, then connect negative lead to battery positive post.
Disconnect voltage regulator wiring connector, then using suitable jumper wire, connect wiring connector green regulator field wire to a suitable
Connect a suitable engine tachometer, then reconnect battery ground cable.
Connect a variable carbon pile rheostat to battery terminals, ensuring carbon piles are in "open" or "off" position.
Start engine and operate at idle speed, then adjust carbon pile and engine speed to maintain a 20 amp circuit flow. Note voltmeter reading.
If a higher than specified voltage drop is indicated, clean and tighten all connectors in charging circuit. A voltage drop test may be performed at
If charging circuit resistance test was satisfactory, disconnect battery ground cable, then the ammeter, voltmeter and carbon pile.
Remove jumper wire, then connect regulator wire connector.
Connect battery ground cable.
