3. Check switch operation (low pressure).
(a) Battery disconnect and engine start
switches remain in OFF position (TM
5-3805-291-10).
(b) Wiring harness remains disconnected
from switch and ECM.
(c) Connect one lead from a multimeter to
contact A (wire C216-BK) of
connector on switch.
(d) Connect other lead from a multimeter
to contact B (wire 417-GY) of
connector on switch.
(e) Measure resistance between contact A
(wire C216-BK) and contact B (wire
417-GY). Note resistance.
(f) Disconnect multimeter lead from
contact B (wire 417-GY) and connect
lead to contact C (wire 484-YL).
