Replacing the Controller Fuses
To replace the controller fuses:
1.
The light bar controller has four 15 A fuses and one 5 A fuse. To see if a fuse
is bad, inspect the horseshoe-shaped wire on its side to see if it has burned
through and broken the circuit. See Figure 19 on page 46. For replacement
fuses, see Table 15 on page 51.
2.
To remove a fuse, pull it straight out to avoid damaging the connector.
