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.
PRIMARY COMPONENTS: Cont. IGNITION SWITCH: Pole Contact per Key Position. OFF – “G” Green is Ground + “M”, Yellow Wire the Magneto. + “R” Accessory. Are Closed Circuits. Engine Magneto is grounded and will not produce spark to spark plugs. “B” Red Positive is isolated. Not feeding other circuits. ON – “B” Red Positive from Battery to “L” Red Wire to feed circuits & “R” Positive to Acc. Positive Current is sent to components as PTO switch, relay, seat, and engine harness.
BRAKE SWITCH: This is a manually operated safety switch. When the brake is in the engaged position, switch button in, the orange wire (starter circuit) is closed allowing current to pass thru from the ignition switch. The circuit between the green ground and yellow (magneto) is open. With the brake disengaged, the open and closed circuits are reversed. Yellow Wire to Relay (87a). Closed to Ground, Brake Off Orange from Ignition Switch to PTO Switch.

DIAGNOSTICS: PREVENTION: The cause of most electrical issues are moisture resulting in corrosion, loose wires or contacts ( mainly ground wires & cables ) or damaged wires. It is highly recommended that a part of regular service is to inspect the electrical system including all related components. This is especially true in areas of high humidity, exposure to lawn chemicals, units stored outdoors or units that are pressure washed frequently.
