Cub Cadet 782 Wiring

The Cub Cadet 782 is a riding lawn mower with a Kohler engine. The wiring connecting the engine's spark plug, battery, starter motor, governor, solenoid and control functions may require occasional troubleshooting if the mower begins to exhibit problems with starting or running, particularly if it's many years old or has otherwise endured a lot of service. You can troubleshoot your Cub Cadet 782's wiring and get your machine back to proper operating condition on your own, even if you have no experience with fixing lawn mowers.

Instructions

    • 1

      Park the Cub Cadet 782 mower and cut the ignition. Open the engine hood.

    • 2

      Check the spark plug's wiring. The spark plug sits on the right side of the Cub Cadet's Kohler engine and is attached to the engine via a thin black wire called the ignition wire. Ensure that this ignition wire is still plugged into the rear (or top) of the spark plug. If it is not, reinsert it.

    • 3

      Check the Cub Cadet's battery. You'll find it in front of the engine block; it is easily recognizable with its black rectangular box shape and the visible bolts on its top. A terminal wire extends out of connection posts on each side of the battery. One terminal wire is red (positive) and the other is black (negative). Ensure that each terminal wire is tightened into place on the connection point. Use a socket wrench to twist and tighten the wires over the side bolts on the battery by turning the wrench clockwise.

    • 4

      Trace the red and black terminal wires back to the rectangular solenoid block, which is further back on the Cub Cadet's engine assembly. The red and black terminal wires should connect to bolts on opposite sides of the solenoid. If they do not, loop the open end of each terminal wire over its respective solenoid bolt, then tighten it into place by turning the bolts clockwise using your socket wrench.

    • 5

      Ensure that the wire harness is securely positioned over the top of the solenoid. This wire harness consists of a web of small, thin wires that have to be secured to the Cub Cadet's solenoid via the retainer clip at the center of the harness. Use the tip of a knife or the edge of a flat-head screwdriver to pry under the retainer clip in order to pop it upward to allow you to reset the wire harness if it has slipped off part of the solenoid.

    • 6

      Reposition the wire harness so that it sits firmly centered on top of the solenoid. The wire ends will need to make contact with the bolt connection points on top of the solenoid. Push down on the retainer clip to snap it back into place and secure the harness.

    • 7

      Look to the right side of the solenoid. A second wire connects here. This thin black cord is the wire for the starter motor. Ensure that this wire is connected to the other small bolt on the right side of the solenoid. Loop its end back over the bolt if it has come loose, then tighten it into place by turning the bolt clockwise with your socket wrench.

    • 8

      Find the distinctive circular flywheel piece on the top of the Cub Cadet's engine block. The flywheel is covered with an iron shroud that is held in place with bolts. Remove these bolts with the socket wrench and set the shroud aside.

    • 9

      Look at the right side of the flywheel now that the shroud has been removed. A flap is connected via a wire to a bolt here. This flap and the wire correspond to the governor, which limits the top speed of the engine. Ensure that this wire is still connected to the bolt. If it is not, loop it over the bolt and tighten the bolt with clockwise turns from your socket wrench.
