(a) Wiring harness remains disconnected
from parking brake oil pressure switch.
(b) Activate switch by starting engine and
disengaging parking brake (TM 5-
3805-291-10).
(c) Connect one lead from a multimeter to
contact A of harness connector on
switch.
(d) Connect other lead from a multimeter
to contact B of harness connector on
switch.
(e) Measure resistance between contact A
and contact B. Note resistance.
(f) Disconnect multimeter lead from
contact B and connect lead to contact C.
(g) Measure resistance between contact A
1. If resistance from contact A to contact
and contact C.
B is less than 5 Ohms, and resistance
from contact A to contact C is greater
than 5 Ohms, go to Test 3.
2. If resistance measurements do not differ
for both contacts or measurements have
not changed from previous test, replace
parking brake oil pressure switch (WP
0086 00).
3. Check ground circuit of switch in wiring
harness.
(a) Turn engine start and battery
disconnect switches to OFF position
(TM 5-3805-291-10).
(b) Disconnect wiring harness connector
from pressure switch (WP 0086 00).
1. If resistance is less than 5 Ohms, go to
(c) Measure resistance between frame
