The VOES is either on or off in terms of how it operates.Testing it is easy, disconnect the electrical connector at the switch and check for continuity on the switch side of the connector, there should be none. If there is it has failed in the on position
If there is no continuity you then unplug the vacuum hose to it and check continuity while applying vaccum with a hand vac pump. you should hear an audible click and see continuity on the meter between 4-7 inches of vacuum.
You're welcome, let me know how it goes.
