Always identify and correct the cause of a blown fuse
before restarting the generator set. Refer to Section 3,
Troubleshooting, for conditions that may indicate a
blown fuse. Replace blown fuses with identical
replacement parts.
6.14 Starter Relay
The starter relay contains an internal diode across the
relay coil. See Figure 6-42. Continuity checks across
the coil terminals will show continuity (low resistance) in
one direction and an open circuit in the other.
Figure 6-43 shows the starter relay connections.
