Fig. 1 Charging Circuit Resistance Test. Except Units w/regulator In Engine Electronics:





EXCEPT UNITS w/REGULATORS IN-ENGINE ELECTRONICS

1. Disconnect battery ground cable. Disconnect "Bat" lead at the alternator.
2. Complete test connections as shown. Do not connect blue J2 lead of wiring connector to ground. Do not spread connector terminals with jumper wire.
3. Connect battery ground cable, start engine and operate at idle.
4. Adjust engine speed and carbon pile to obtain 20 amps in the circuit and check voltmeter reading. Reading should not exceed .5 volts. If a voltage drop is indicated, inspect, clean and tighten all connections in the circuit. A voltage drop test at each connection can be performed to isolate the trouble.

UNITS w/REGULATOR IN-ENGINE ELECTRONICS

1. Disconnect battery ground cable and the "Bat" lead from alternator output terminal.
2. Complete test connections as shown.
3. Remove air hose between power module and air cleaner, then the wiring harness electrical connector.
4. Connect a suitable jumper wire from wiring harness connector green wire terminal to ground. Do not connect blue J2 lead of wiring electrical connector to ground.
5. Connect battery ground cable, then start engine and operate at idle.
6. Adjust engine speed and carbon pile rheostat to obtain 20 amps in the circuit and check voltmeter reading. Reading should not exceed .5 volts. If a higher voltage drop is indicated, inspect, clean and tighten all connections in the circuit. A voltage drop test at each connection can be performed to isolate the problem.
