INJECTOR SOLENOID CIRCUIT TEST - CONTINUED
8.
Check injector harness under valve cover for an open or short circuit.
WARN I N G
Electronic fuel injector system uses 90 to 120V. Do not touch any components during testing. Failure to
comply may result in injury to personnel or damage to equipment.
a.
Place battery disconnect switch in OFF position (TM 5-3805-291-10).
b.
Remove valve cover to gain access to suspect injector (WP 0024 00).
c.
Disconnect harness connector from suspect injector (WP 0187 00).
427-C0699
d.
Thoroughly clean terminals on injector solenoid and on harness connector.
e.
Use a jumper wire to short circuit connector terminals for suspect injector. This will effectively replace injector
solenoid with a short circuit.
f.
Place battery disconnect switch in ON position (TM 5-3805-291-10).
g.
Perform injector solenoid test at least two times.
N OT E
Injector solenoid that shares supply wire of injector that is short circuited may indicate a false test result.
Disregard this test result.
h.
Place battery disconnect switch in OFF position (TM 5-3805-291-10).
i.
Remove jumper wire from injector connector. This will effectively replace injector solenoid with an open circuit.
j.
Place battery disconnect switch in ON position (TM 5-3805-291-10).
k.
Perform injector solenoid test at least two times.
l.
Place battery disconnect switch in OFF position (TM 5-3805-291-10).
