Electrical System Quick Checks Battery Test (Open Circuit Test) Use a multimeter to measure the voltage between the battery terminals. Set multimeter to the DC volts setting. The battery should be at a temperature of 60 o F to 100 o F(16 o Cto 38 o C). The ignition key should be off and all accessories turned off. Connect the positive (+) meter lead to the positive battery post and the negative (--) meter lead to the negative battery post. Voltage Measured Battery Charge Level 12.68 V (or higher) Fully charged (100%) 12.45 V 75% charged 12.24 V 50% charged 12.06 V 25% charged 11.89 V 0% charged NOTE: This test provides a relative condition of the battery. Load testing of the battery will provide additional and more accurate information. Charging System Test This is a simple test used to determine if a charging system is functioning. It will tell you if the charging system has an output, but not its capacity. Use a digital multimeter set to DC volts. Connect the positive (+) multimeter lead to the positive battery post and the negative (--) multimeter lead to the negative battery post. Keep the test leads connected to the battery posts and record the battery voltage. NOTE: Upon starting the engine, the battery voltage will drop and then should increase once the engine is running. NOTE: Depending upon the condition of the battery charge and battery temperature, the battery voltage will increase at different rates as the battery charges. Start the engine and run at high idle (2870 RPM). Allow the battery to charge for at least 3 minutes. Record the battery voltage. After running the engine for at least 3 minutes, battery voltage should be at least 0.50 volt higher than initial battery voltage. An example of a charging system that is functioning: At least 0.50 volt over initial battery voltage. Initial Battery Voltage = 12.30 v Battery Voltage after 3 Minute Charge = 12.85 v Difference = +0.55 v Check Operation of Interlock Switches CAUTION Do not disconnect safety switches. They are for the operator’s protection. Check the operation of the interlock switches daily for proper operation. Replace any malfunctioning switches before operating the machine. Interlock switch operation is described in the Operator’s Manual. Testing of interlock switches and relays is included in the Component Testing section of this Chapter.

Adjustments Wing Deck Position Switches Adjustment 1. Park machine on a level surface, lower cutting deck, stop engine, engage parking brake and remove key from the ignition switch. 5 2. Remove switch cover from deck to allow access to position switch that requires adjustment. NOTE: Use Deck Proximity Switch Adjustment Tool (TOR4095) to assist with switch adjustment (see Special Tools). 3. Loosen two (2) lock nuts that secure switch bracket to center cutting deck (Fig. 7). 4. When adjusting switch location, the target surface of position switch should be approximately 0.188” (4.8 mm) from actuator tab on wing deck link (Fig. 8). 5. When wing deck position switch is properly adjusted, hydraulic motor on wing deck should turn off when wing deck is raised and wing deck latch opens. 6. For switch testing information, see Wing Deck Position Switches in the Component Testing section of this chapter. 6 1. Position switch 2. Lock nut (2 used) 3. Flat washer (2 used) 4.
