7-1. DESCRIPTION AND DATA
a. This section provides description and data for the alternator, starter motor, and solenoid.
b. M809 series vehicles use alternators with an adjustable voltage range of 26 to 30 volts and
maximum output of 60 or 100 amperes. Alternators are air-cooled by a fan located on the drive
end directly behind the pulley. Alternator maintenance, repair, and testing are covered in
TM 9-2920-225-34.
c. M809 series vehicles use a 24-volt starter motor. The starter motor has a piggy back
mounted solenoid plunger and a pinion shifting mechanism which is totally enclosed. The
motor is completely sealed. Starter motor maintenance, repair, and testing are covered in
TM 9-2920-242-35, TM 9-2920-243-34, and TM 9-2920-248-35.
