machine ground.
ceed to Test Step 15.
Test Step 5. Test 200-BK Ground
Circuit to Front Windshield Wiper
Washer Switch for High Resis-
tance or Open.
1. Turn ignition switch and battery
disconnect switch to OFF position
(TM 5-3805-293-10).
2. Using digital multimeter, measure
Resistance 5.0 Ohms or Greater -
resistance between R-C33 termi-
Proceed to Test Step 6.
nal 3 (WP 0009, Figure 371) and
Resistance Less Than 5.0 Ohms -
machine ground.
Proceed to Test Step 16.
Test Step 6. Test 200-BK Ground
Circuit for High Resistance or Open
in Cab Lower Wiring Harness.
1. Disconnect cab lower wiring har-
ness connector P-C3 (WP 0009,
Figure 34) from cab upper wiring
harness connector R-C1 (WP
0009, Figure 33) (WP 0266).
2. Using digital multimeter, measure
Resistance 5.0 Ohms or Greater -
resistance between P-C3 terminal
Proceed to Test Step 7.
14 (WP 0009, Figure 34) and
Resistance Less Than 5.0 Ohms -
machine ground.
Proceed to step 3.
3. Using digital multimeter, measure
Resistance 5.0 Ohms or Greater -
resistance between P-C3 terminal
Proceed to Test Step 7.
15 (WP 0009, Figure 34) and
Resistance Less Than 5.0 Ohms -
machine ground.
Replace cab upper wiring harness
(WP 0265).
Install cover on fuse box (TM 5-3805-
293-10).
Proceed to step 4.
4. Turn battery disconnect switch
and ignition switch to ON position
(TM 5-3805-293-10).
