Cub Cadet TANK S Series: Electrical System - Manual (Page 3)

PIMARY WIRE COLOR DESIGNATION:
RED or Combination as Red w/ Black Stripe.
POSITIVE (+) power supply.
Circuit runs from battery, thru a fuse, to the ignition switch for distribution to components as
Starter Solenoid (orange wire), Relays and Charging System.
GREEN:
NEGATIVE (-) main Ground Circuit.
Main Circuit runs from Battery to Engine Block and to components requiring constant ground.
ORANGE or Combination as Orange w/ Black or White Stripe.
POSITIVE (+) power supply to activate the engine starter solenoid.
Circuit begins at the ignition switch and is tied directly into safety switches before ending at the
starter solenoid.
Example, when the brake is engaged, the brake switch makes the orange wire circuit and
allows the current to flow to the next component. When the brake is off the circuit is broken
within the switch and the current cannot flow to the next component, therefore the engine starter
will not engage.
YELLOW or Combination as Yellow w/ Black or White Stripe.
NEGATIVE (-) circuit ground to engine magneto.
Circuit begins at the ignition switch and is tied directly into safety switches and relays before
ending at the engine. This circuit provides a means to ground the engine magneto which in turn
does not allow the engine to provide spark to the spark plugs.
BLUE or Other Colors:
These are secondary circuits providing current to components and accessories.
Example, BLUE Wire provides positive (+) current to activate the PTO clutch.
PRIMARY COMPONENTS:
BATTERY:
12 Volt, CA @ 32 deg.F = 320, CCA @ 0 deg.F = 260.
NEGATIVE CABLE to the engine block mounting bolt.
POSITIVE CABLE to the engine starter solenoid.
POSITIVE WIRE, main circuit to fuse and ignition switch.
Note: On Diesel, EFI or DFI engines, some components are connected directly to the battery
with their own circuit and fuse. Consult the appropriate wire schematic for routing.
FUSE:
Blade Type, Automotive, 20 amp for main circuit from battery to ignition switch.
Note: On TANK-S Units the fuse & labeled holders are mounted on the inside lip of the RH side
control panel next to the battery.
SEAT SWITCH:
The operator presents (seat) switch is integrated in the seat cushion. When the operator is in
the seat, a positive circuit is completed sending current to a relay or other safety component
within the system.
