Constant Power Fuse
Models equipped with electric start or an IDD have a battery/electric start wire harness. The 2 amp constant power fuse is located in the hood harness. This fuse protects KEY ON power at the ignition switch. KEY ON power supplies battery voltage to the IDD and GPS puck.
If the IDD does not turn on when the key is in the ON position, check for a blown fuse. If the fuse is blown, inspect the constant power circuit. Repair or replace any damaged components before replacing the fuse.
