MALFUNCTION TEST OR INSPECTION CORRECTIVE ACTION ALL VEHICLE ELECTRICAL SYSTEMS INOPERATIVE (Contd) Test 2. Disconnect battery ground cable (WP 0126 00) and test battery cables as follows: 1. Set multimeter to RX 1 scale. 2. Check for continuity of battery cables no. 6 and 68 and for worn or frayed insulation. 3. Check continuity of battery cable no. 7 to frame ground. 4. Connect battery ground cable (WP 0126 00) and proceed to test 3. Test 3. Check for battery voltage at starter solenoid. 1. Set multimeter to a voltage range that will measure 24 VDC. 2. Check lead no. 6 at contact 2 of starter solenoid for battery voltage. 1. If resistance is greater than 1 ohm, repair or replace battery cables (WP 0126 00 and WP 0090 00). 2. If insulation is worn or frayed, repair or replace battery cables (WP 0126 00 and WP 0090 00). 1. If resistance measure greater than 1 ohm, clean cable no. 7 connection at right-hand frame rail. 2. If continuity is still greater than 1 ohm, repair or replace battery cable (WP 0126 00 and WP 0090 00). If battery voltage is not present, clean connections of lead no. 6 at contact no. 2 of starter solenoid (WP 0088 00).
