Alternator/Regulator

This roller is equipped with a 20-amp charging system.This system uses three charge coils connected in parallel. The windings of each coil are wound with heavy-duty insulated wire and are further protected by insulating material for long life. A voltage regulator is provided to control the amount of charge voltage being delivered to the 12 volt electrical system. For servicing this charging system, contact your Honda dealer.

Neutral Safety Switch

The travel lever is provided with a neutral safety switch (Figure 35) that prevents the engine from starting when the lever is in the forward or reverse drive position. Lever must be placed in the neutral position in order for the starter to function.

Figure 35. Safety Switch

To check this switch, remove the panel located below and to the rear of the floor. This switch is mounted to the lower forward/ reverse lever mechanism. Disconnect the white and green wires. Place the lever in neutral and test for continuity. Place the lever in forward or reverse; no continuity should be present. Repair or replace as required.

Vibrator Solenoid

The vibrator solenoid (Figure 36) is located in the manifold valve block and is controlled by the vibration switch located on top of the travel lever.This solenoid controls the vibration control valve which supplies hydraulic oil to the vibration drive motor.

To test the vibration solenoid, turn the ignition switch on. Check for proper supply voltage and ground. If proper voltage and ground are present, check the solenoid for continuity. If no continuity, replace the solenoid coil. If continuity is present, place your hand on the solenoid and turn the switch to the ON position; movement should be felt.

DO NOT START THE ENGINE FOR THIS TEST.

Battery

Mishandling of the battery shortens the service life of the battery and adds to maintenance cost. When handling the battery do the following:

„„Be careful not to let the battery electrolyte come in contact with your body or clothing.

„„Always wear eye protection and rubber gloves, since the battery contains sulfuric acid which burns skin and eats through clothing.

„„Check the battery regularly and make sure that each electrolyte level is to the bottom of the vent well (Figure 42). If necessary, add only distilled water in a well- ventilated area.
