How To Use This Manual
Power Distribution Schematics (cont'd)
From Fuses to Relays and Components
The second half of Power Distribution shows the wiring "From Fuses to Relays and
Components." This can speed your troubleshooting by showing which circuits share luses. lf
Power Distribution shows thal an inoperative circuit and another circuit share a fuse, check a
component in the other circuit. lf it works, you know the fuse is good and power is available to
the inoDerative circuit.
