82Maintenance Instructions ADJUSTMENTS/ELECTRICAL SYSTEMChecking the Grass-Pak® SwitchAdjustment (When Horn Sounds at the Wrong Time)Very little, if any, adjustment to the Grass-Pak®switch is required. However, to fine tune the timingof the full signal, the vertical position of the switchvane is adjustable approximately 3/4 in. (1.9 mm).1. Loosen the screw mounting the vane on theswitch and adjust the position of the vane as fol-lows:a. Move the vane UP to delay the signal.b. Move vane DOWN to advance the signal.2. Retighten the screw.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” signalwith a little advance warning before overfillingand clogging of the grass delivery chute begins (re-gardless of mowing conditions).Grass-Pak® Switch Vane AdjustmentELECTRICAL SYSTEMFor troubleshooting, refer to Wiring Diagram.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.
