Battery Cable Fusible Link Re-
placement (Battery to Starter)
Removal
1
If a battery side fusible link becomes
an open circuit, power will not be sup-
plied to the cab power stud on that
circuit (no continuity between the cab
stud and starter solenoid). To verify
fusible link failure, check for a visible
break in the fusible link.

WARNING
Disconnect the positive (+) and negative (-) terminals
before beginning this procedure to prevent electric
short circuit. Failure to do so could cause serious com-
ponent damage. Disconnect the ground terminal first.

CAUTION
Check the electrical system for a short circuit before
beginning this procedure to prevent another fusible
link from melting. Failure to repair the short circuit
which caused the fusible link to melt will result in the
new fusible link melting.
4
Loosen the bolt that goes through the
battery cable clamping bracket. Re-
move the cable from the clamp. This
will allow the cable to be removed
from the solenoid.
