Specifications

- TKS fuel path is in the normally open position. Electric power causes a
wax expanding device to expand thus causing the needle to meet the
seat and close the additional TKS fuel path.
x Electric Paths:
- There are two paths for electricity to get to the module: one via an
additional oil pressure switch and one via an additional engine coolant
switch.
- Additional Oil Pressure Switch
:
An oil pressure switch is added to the system using a “T” fitting. One
lead is wired into the purple wire in the harness, the other to the TKS
unit.
When oil pressure exceeds 4psi (i.e. engine running) the oil pressure
switch closes sending power to the TKS unit. This begins heating the
element and causing closure within 6-10 minutes.
Power will continue to flow to the TKS unit as long as there is power on
the purple wire and
there is oil pressure. Thus, if the key is left in the
run position, with the engine not running, the TKS unit will not receive
power.
