Field Circuit Drain Test

Connect the multimeter negative lead to the Generator (GEN) rear housing for all of the following voltage readings:
1. With the ignition switch in the off position, connect the voltmeter positive lead to the voltage regulator F-terminal. The multimeter should indicate battery positive voltage (B+) if the system is operating normally. If less than battery positive voltage (B+) is indicated, perform Step 2 to find the cause of the current drain.
2. Measure the voltage at the I-terminal. If voltage is indicated, repair the I-circuit from the ignition switch to eliminate the voltage source.
