If continuity is present as described, proceed to #4. If continuity is not present as described, replace the switch. 4. Check for continuity across the .25" terminals of the switch when it is in the “ON” position. Continuity must not be present in the upper “OFF” position. If continuity is present as described, reconnect the wires, the switch is operating properly. If continuity is not present as described, replace the switch. Removal and Replacement: 1. Remove all wires from the switch terminals. 2. Compress the clips inside the front of the hopper housing and gently push the switch through the opening. 3. Push the new switch into the opening and spread the clips to retain the switch in the hopper housing. 4. Reconnect all the wires to the switch terminals. 5. Refer to Fig. 16 when reconnecting the wires. P1057 P1028 Solenoid (Model LPG-2E) P1058 Location: The solenoids are located inside the hopper housing behind the left and right side of the motor. Test Procedure: 1. Disconnect grinder from the power source. 2. Remove both wires from the solenoid coil terminals. 3. Check the voltage across the red wire and the violet wire removed from the right solenoid or the red wire and the orange wire removed from the left FIG. 15 OFF/ON/START SWITCH FIG. 16 OFF/ON/START SWITCH TERMINALS (Viewed from rear) FIG. 17 SOLENOIDS RED from Motor RED to Left and Right Solenoid - LPG-2E BLK to Power Cord - LPG YEL to Timer P1-5 - LPG-2E WHI/BRN to Timer P1-5 - LPG WHI from Power Cord to Hopper Selector Switch - LPG-2E WHI/BLU to Timer P1-4 - LPG 27091 111598 SERVICE (cont.) Timer (Model LPG-2E) P1061FIG. 20 TIMER Location: The timer is located inside the hopper housing just behind the left solenoid. Test Procedure: 1. Disconnect grinder from the power source. 2. Insert the leads of a voltmeter set to read at least 120 volts AC, along side the red wire (terminal 8) and the white wire (terminal 2) of the harness plug. Place the Off/On/Start switch in the “ON” center position. Connect the grinder to the power source. The indication must be 120 volts AC. 3. Disconnect the grinder from the power source. If voltage is present as described, proceed to step #4. If voltage is not present as described, refer to the wiring diagram and check the grinder wiring harness. 4. Place the hopper selector switch in the left position. 5. Insert the leads of a voltmeter set to read at least 120 volts AC, along side the red wire (terminal 8) and the orange wire (terminal 10) of the harness plug. Place the Off/On/Start switch in the “START” lower position. Connect the grinder to the power source. The indication must be 120 volts AC for the set gate time and return to 0 volts. 6. Disconnect the grinder from the power source. If voltage is present as described, proceed to step #7. If voltage is not present as described, replace the timer. 7. Place the hopper selector switch in the right position. 8. Insert the leads of a voltmeter set to read at least 120 volts AC, along side the red wire (terminal 8) and the violet wire (terminal 9) of the harness plug. Place the Off/On/Start switch in the “START” lower position. Connect the grinder to the power source. The indication must be 120 volts AC for the set gate time and return to 0 volts. 9. Disconnect the grinder from the power source. If voltage is present as described, proceed to step#10. If voltage is not present as described, replace the timer. 10. Insert the positive (+) lead of a volt meter set to read at least 120 volts DC, along side the black wire (terminal 7) of the harness plug and insert the negative (-) lead along side the white/black wire (terminal 6) of the harness plug. Place the Off/On/Start switch in the “START” lower position. Connect the grinder to the power source. The indication must be 120 volts DC for the set gate time plus clean out time and return to 0 volts. If voltage is present as described the timer is operating properly. If Voltage is not present as described, replace the timer. Removal and Replacement: 1. Disconnect the main wiring harness plug from the terminal block on the timer. 2. Remove the two timer dial knobs located on the rear panel of the grinder. 3. Remove nut and internal tooth lockwasher securing dials to the rear panel. 4. Loosen the two #8-32 pan head screws securing the timer and timer mounting bracket to the motor support plate. 5. Remove timer and timer mounting bracket from the grinder. 6. Remove the four #6-32 keps nuts securing the timer to the mounting bracket. Leave the four spacers on the mounting bracket studs. 7. Place new timer over the studs on the mounting bracket and secure with four #6-32 keps nuts. 27091 111598 16 SERVICE (cont.) Timer (Model LPG-2E) 8. Slip timer and timer mounting bracket under the two screws on the motor support plate and tighten screws. 9. Locate the left and right timer dials in their proper place on the rear panel and secure with nuts and internal tooth lockwashers. 10. Place timer knobs on timers. 11. Reconnect harnes...
