DFI Fuse Removal
Remove the seat (see Frame chapter).
Pull the lock [A] and open the lid [B].
Pull out the DFI fuse [C] from the case with needle nose
If a fuse fails during operation, inspect the DFI system to
determine the cause, and then replace it with a new fuse
of proper amperage.
DFI Fuse Inspection
Remove the fuse (see DFI Fuse Removal).
Inspect the fuse element.
If it is open, replace the fuse. Before replacing a blown
fuse, always check the amperage in the affected circuit.
If the amperage is equal to or greater than the fuse rat-
ing, check the wiring and related components for a short
Fuse Element [B] and Blown Element [D]
When replacing a fuse, be sure the new fuse
matches the specified fuse rating for that circuit.
Do not use a fuse rated for other than amperage
and voltage specified in the Wiring Diagram.
DFI Main Relay Removal
Never drop the relay, especially on a hard surface.
Such a shock to the relay can damage it.

DFI Main Relay Inspection
Remove the DFI main relay (see above).
Connect the hand tester [A] and one 12 V battery [B] to
the relay terminal [C] as shown.
