Accessory Solenoid
The accessory solenoid provides a current supply to the
spray system and optional accessories (e.g. foam mark-
ers). The solenoid is energized when the ignition key
switch is in the RUN position. The accessory solenoid is
attached to the electric panel under the operator seat
(Fig.23).
Testing
1. Make sure engine is off. Disconnect battery cables
from battery making sure to disconnect negative (–)
cable first and then positive (+) cable.
2. Raise operator seat and locate accessory solenoid.
Put labels on wires for proper installation after repairs
are completed. Disconnect machine harness wires from
solenoid.
3. Apply 12 VDC (+) to one solenoid coil post and
ground the other solenoid coil post. The solenoid should
click. Using a multimeter (ohms setting), make sure re-
sistance across the main contact posts is less than 1
ohm.
4. Remove voltage from solenoid coil post. The sole-
noid should click. Make sure resistance across the main
contact posts is infinite ohms (no continuity).
5. Replace accessory solenoid if necessary.
6. Reconnect electrical connections to solenoid.
7. Reconnect battery cables to battery making sure to
install positive (+) cable first and then negative (–) cable.
