and terminal A
(WP 0012, Figure 169).
Resistance should be less
than 1.0 Ohm.
b. Between connector terminal B
and terminal C
(WP 0012, Figure 169). There
should be no continuity.

continuity.
d. Between connector terminal A
and terminal B
(WP 0012, Figure 169). There
should be no continuity.
Test Step 2. Test for Shorted Push
