Cowl Lock and Tension Point Hall Sensors
Two hall sensor switches are installed on the left side top lock drive assembly. Both sen-
sors receive power and ground from the CVM. One switch is the soft top locked to the
windshield frame input (cowl lock). The second switch is the top frame raised past the ten-
sion point input. As the slide assembly on the worm gear moves, it covers and uncovers
the hall sensors to cause the high/low switching to take place.
The cowl switch input provides a low signal when the top frame is unlocked from the wind-
shield (LED in the soft top switch will start to flash).
The tension point switch input provides a high signal when the top frame is raised past the
tension point.
