Testing

Turn ignition switch to the ON position (do not start en-

gine). With the fuse installed in the fuse block, use a

multimeter to verify that 12 VDC exists at both of the ter-

minal test points on the fuse. If 12 VDC exists at one of

the fuse test points but not at the other, the fuse is faulty.

If necessary, make sure that ignition switch is OFF and

key is removed from switch. Remove fuse from fuse

block and check that fuse has continuity across the fuse

terminals.
