• The blue wire triggers the solenoid.
• The violet wire carries charging current from the
regulator / rectifier.
• The heavy gauge red cable carries battery cur-
rent to the starter and carries charging current to
the battery while the engine is running.
• The smaller gauge red wire is not used in this

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.
