W1 J1 Pin 1 and W1 J1 Pin 2
proceed to next test.
(WP 0451, Vol 3, Figure 1).
2. If voltage reads below 22 VDC,
turn keyless engine switch to the
OFF position (TM 5-3895-385-
10) and proceed to next
malfunction.
3. Measure voltage (WP 0443, Vol

(WP 0451, Vol 3, Figure 1).
2. If voltage reads below 22 VDC,
turn keyless engine switch to the
OFF position (TM 5-3895-385-
10), and replace main wiring
harness (WP 0373, Vol 2).
4. Measure voltage (WP 0443, Vol

(WP 0451, Vol 3, Figure 1).
2. If voltage reads below 22 VDC,
turn keyless engine switch to the
OFF position (TM 5-3895-385-
10), and replace main wiring
harness (WP 0373, Vol 2).
5. Measure voltage (WP 0443, Vol
