8. First make a note of how the wires (piggyback and single) are
connected to the two terminals on the microswitch, and then
disconnect these wires from the terminals (see Figure 50).
NOTE:
It is always recommended to label and tag all wires and
harnesses prior to disconnecting them, so as to correctly identify
their connections/locations when reassembling.
HINT:
Alternatively, you can photograph the wire connections
prior to disconnecting (for example, with your mobile phone).
9. Detach the standard valve from the microswitch by removing and
retaining the T-10 screw, and then pulling the microswitch off the
alignment pin on the standard valve (see Figure 51).
10. Replace the microswitch if needed.
Gas Leaks
Carefully check for gas leaks at each gas component that was
removed, replaced, or otherwise serviced using a gas leak detector or
bubble test.
