If adjustment is required, hold the Grass-Pak ®switch mount bracket firmly, grasp the switch andbracket and bend it down. Adjustments shouldbe done in very small increments checking themeasurement each time until the recommendedmeasurement is achieved. This measurement isapplicable to all catcher box sizes.NOTE: It will not be possible to adjust the switch togive a signal at the precise instant the catcher is fullfor a wide variety of mowing conditions. For exam-ple, wet heavy grass will fill the catcher differentlythan dry fluffy grass, causing the signal to come ona little sooner or later than usual. Primarily, theswitch should be adjusted to give the “full” signal witha little advance warning before overfilling andclogging of the grass delivery chute begins (regard-less of mowing conditions).ELECTRICAL SYSTEMFor troubleshooting, refer to Wiring Diagram.IMPORTANT: For Model MTEFI, an illuminated En-gine Service Light on the control panel means that afault has been detected in the electrical/fuel system.Contact an authorized Kohler Service Dealer to di-agnose the fault.IMPORTANT: Disconnect both battery cables be-fore unplugging any wiring connectors or making re-pairs on the electrical system.IMPORTANT: Disconnect the battery cables beforeunplugging and removing the instrument panel.Circuit BreakersA master circuit breaker is mounted on a bracket be-hind the battery.
