DR-10D Checking Fused J2 to Logic Module

1. With logic module red connector disconnected, connect a voltmeter to terminal No. 7 or 8 of red connector and ground.
2. Turn ignition switch to Run position.
3. If voltmeter reads within 1 volt of battery voltage, check terminal in terminal Nos. 7 and 8 for poor connection. If connection is good, replace logic module.
4. If voltmeter indicates no voltage, repair fused J2 wire to power module for an open circuit.
