The auxiliary start receptacle is located on the right side of the machine, in the battery compartment.

Some AVSpare products may be equipped with auxiliary start receptacles as standard. All other machines can be equipped with a receptacle from parts service. Then, a permanent receptacle is always available for jump starting.

There are two cable assemblies that can be used to jump start the stalled machine. You can jump the machine from another machine that is equipped with this receptacle or an auxiliary power pack. Your AVSpare dealer can provide the correct cable lengths for your application.

1. Determine the reason that the engine will not start. Refer to Special Instruction, SEHS7768, "Use of a 6V-2150 Starting/Charger Analyzer Group" for further information. Use this procedure if the machine does not have a diagnostic connector.
