(1) How does a wire with one end not attached to anything (free end is not electrically attached to anything) "act as a resistor".*
(2) Assuming there is an answer to (1) other than "it doesn't", what is this resistor doing, and to what circuit?
(3) Assuming there is a valid answer to (2), how does this resistance change the switching action of a mechanical pressure switch?
(4) Why does the TSB specifically call this wire a "vent" if it doesn't act as a - ummm - vent?
*Actually, I am looking at a brand new pressure switch that I have sitting here ready to put in when the weather warms up, and there is only one terminal on the pressure switch itself (body goes to engine ground) and it connects to the original single factory wire, but the connector body is a 2-cavity one, and this added wire/vent does not electrically connect to anything inside the connector, so this wire/vent actually has *neither* end electrically connected to anything, which makes the concept of it acting as a resistor doubly meaningless.
Seriously - I'm not trying to be a smart
, but these are questions that must be answered to give credibility to your statements that this wire acts as a resistor to correct the reading of a mechanical contact closure and that the wire doesn't act as a vent when the TSB calls it a vent.
