Multiquip AR13D manual Alternator/Regulator, Neutral Safety Switch

AR13D RIDE-ON ROLLER — MAINTENANCE

Alternator/Regulator

The AR13D is equipped with a 40 amp charging system.This system uses three charge coils connected in parallel. The windings of each coil are wound with heave-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 engine dealer.

Neutral Safety Switch

The travel lever is provided with a neutral safety switch (Figure 40) 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.

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.

Battery

Mishandling of the battery shortens the service life of the battery ans 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.

CAUTION - BATTERY ACID BURN HAZARD

If your clothing or skin comes in contact with the battery acid, immediately wash off with running water and get medical attention.

Vibrator Solenoid

The vibrator solenoid (Figure 41) 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 STARTTHE ENGINE FOR

THISTEST

Check the battery regulary 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.
