should be less than 1.0 Ohm.
b. Between connector terminal B
and terminal C (WP 0012,

Test Step 2. Test Voltage to Scraper
Park Brake Pressure Switch.
1. Turn battery disconnect switch and
ignition switch to ON position
(TM 5-3805-296-10).
2. Using digital multimeter

Test Step 3. Test for Shorted Push
Frame Wiring Harness.
1. Turn ignition switch and battery
disconnect switch to OFF position
(TM 5-3805-296-10).
2. Disconnect connector AF-C1
(WP 0012, Figure 164) from
