My convertible top is not working. When I press the switch nothing happens. I am trying to determine if the switch is defective. I attach a diagram of the switch terminals with the appropriate wires attached.
When the switch has no wires attached, there is continuity as follows:
Without pressing the top up or top down button:
Between terminals 1 and 3
Between terminals 2 and 5
When pressing the top up button:
Between terminals 1 and 3
When pressing the top down button:
Between terminals 2 and 5.
Without pressing the top up or down button, there is +12 volts at terminals 1, 2, 3 and 5.
When the top up button is pressed however, contrary to logic, there is no longer +12 volts at terminal 1. Likewise, when the top down button is pressed, there is no longer +12 volts at terminal 2. How can there be continuity but not +12 volts in these two situations? These two illogical situations lead me to believe that there is something wrong with the switch.
The manual for this vehicle describes the operation of the power top as follows:
With the ignition in the On or Accessory position, the top relay and top switch have power available through their respective circuits. When the console switch for the power is toggled up, the up relay coil is energized pulling the Normally Open contact to the common, and power flows thru the up wire on the hydraulic pump. Similarly, when the top switch is toggled down, voltage is supplied to the down wire.
Your help is greatly appreciated.
