ELECTRICAL: STARTER CIRCUIT

29.1. With the key in the START position, terminals B,

S, and L are connected within the switch.
See Figure 29.1.

29.2. Terminal B is connected to the positive post of

the battery through a light gauge wire (red with
black trace) carrying a 20A in-line fuse.

29.3. The S terminal transfers battery power from the

B terminal to an orange wire with white trace (O/
w) when the key is in the START position.

29.4. The orange wire w/white trace leads to the com-

mon spade on the A set of contacts (A-COM)
within the PTO switch. See Figure 29.4.

•

When the PTO switch is turned-off, power goes
from A-COM to A-NC (orange w/ black trace).

•

When the PTO switch is on, the circuit is open.
