Test Step 10. Test Voltage of Battery
Voltage Erratic, Intermittent,
Supply Circuits at Engine ECM.
1. Connect connector EN-C2
or Incorrect - Continued
(WP 0012, Figure 12) to connector
C-C18 (WP 0012, Figure 13).
2. Turn battery disconnect switch and
ignition switch to ON position
(TM 5-3805-298-10).
3. Using digital multimeter
Voltage 18 to 26 V Proceed to step 4.
(WP 0174), test for voltage
Voltage Less Than 18 V Replace
between EN-C1 (WP 0012,
engine wiring harness (WP 0299).
Figure 11) terminal 7 and ground.
Proceed to Test Step 11.
4. Using digital multimeter
Voltage 18 to 26 V Proceed to step 5.
(WP 0174), test for voltage
Voltage Less Than 18 V Replace
between EN-C1 (WP 0012,
engine wiring harness (WP 0299).
Figure 11) terminal 8 and ground.
Proceed to Test Step 11.
5. Using digital multimeter
Voltage 18 to 26 V Proceed to step 6.
(WP 0174), test for voltage
Voltage Less Than 18 V Replace
between EN-C1 (WP 0012,
engine wiring harness (WP 0299).
Figure 11) terminal 15 and ground.
Proceed to Test Step 11.
Voltage 18 to 26 V Replace engine
6. Using digital multimeter
ECM (WP 0265).
(WP 0174), test for voltage
between EN-C1 (WP 0012,
Proceed to Test Step 11.
Figure 11) terminal 16 and ground.
Voltage Less Than 18 V Replace
engine wiring harness (WP 0299).
Proceed to Test Step 11.
Test Step 11. Verify Malfunction Is
Resolved.
1. Ensure all wiring harness
connectors are connected.
2. Install right and left engine access
panel (WP 0348).
3. Install right lower cab access
panels (WP 0347).
4. Start engine (TM 5-3805-298-10).
