(a) Wiring harness remains disconnected
from parking brake oil pressure switch.
(b) Activate switch by starting engine and
disengaging parking brake (TM 5-

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
3. Check ground circuit of switch in wiring
(a) Turn engine start and battery
disconnect switches to OFF position
(b) Disconnect wiring harness connector
from pressure switch (WP 0086 00).
