DR-15D Alternator Field Circuit of Power Module

1. Place ignition switch in the Off position, then disconnect power module 12 way electrical connector.
2. Connect a voltmeter between power module 12 way electrical connector terminal No. 11 and ground, then place ignition switch in the Run position.
3. If voltmeter reading is within 1 volt of battery voltage, check wiring to terminal No. 5 of logic module white electrical connector for an open circuit.
4. If voltmeter indicates no voltage, replace power module.
