System Information
Step 3--Switch OFF
Check component side of circuit breaker for continuity to ground
Continuity to ground. Repair grounded circuit at or before switch.
No continuity to ground, replace circuit breaker.
Step 4--Switch ON
Check component side of circuit breaker for battery voltage
Battery voltage normal. Go to Step 6.
Low voltage, repair high resistance.
No voltage. Go to Step 5.
Step 5
Disconnect wire at battery side of component (G). Switch ON. Check
Battery voltage, repair component.
wire at (G) for battery voltage
No voltage, repair grounded or open circuit at or after switch.
Step 6--Switch ON
Check lead to component at (G) for battery voltage
Battery voltage normal. Go to Step 7.
Low voltage, repair high resistance in circuit between fuse and
9015
component.
05
No voltage, repair high resistance or open circuit between fuse and
