PROBLEM NO. 20
SUPP STER REMAINS ON
INDICATOR LIGHTS
POWER switch ON. Engine running.
Normal steering system operating.
This circuit uses a normally closed paddle-type flow switch which opens when normal steering system flow occurs. When flOW stops (supplemental
steering takes over) the switch closes, lighting the SUPP STER lamp.
NOTE
Make sure arrow on switch points in direction of flow (away from main steering pump).
To troubleshoot: turn POWER switch to OFF, disconnect W/DK BL wire at flow switch and then START engine. If light goes out, replace flow switch,
page 2-315. If
light remains on, W/DK BL 16
gage wire is
shorted between switch and lamp socket. See WIRE and HARNESS TESTING, page 2-66.
