5. The reading on the meter should be within .1
volts of the battery voltage. If it is, the switch box
is working properly and by process of elimina-
tion, the motor is the problem.
NOTE: The motor is not serviceable.
NOTE: If the reading is between .1 volt to 5 volts
look for lose or corroded connections.
NOTE: If there is no voltage reading, check the
fuse at the motor before testing further.
