Ignition Fuse
See Figure 7-39. The ignition fuse is in the fuse block under
the seat. Always replace the fuse with another 7.5 ampere
fuse.
Diodes
The fuse block contains two diodes. A diode acts as a one
way switch which permits current flow in one direction, but not
in the other.
The reference numbers below correlate with the circled num-
bers in the 7.11 STARTER/IGNITION INTERLOCK flow
charts.
1. Check diode with an ohmmeter as shown in Figure 7-40.
2. Check diode polarity as shown in Figure 7-41.
3. Replace diodes as necessary.
