Nick:
It seems as though you have received a reply to this, although
the reply did not make it to the list, perhaps because the footer was
not removed before it was sent.
Anyway, at the risk of being redundant, here are the
connections:
White/Purpl | | Black (Gnd)
(ARO Valve) | |
_____
White/Brn (lamp)
Blk is shorted to Wh/Brn when the engine is not running. No
other pins should be shorted. I don't trust this however, because the
switch can fail in such a way as to have the Wh/Brn & Blk pins shorted,
so it is not an absolute check of functionality. In my case gently
tapping the switch on my workbench caused one suspect switch to go
completely open, and another tap would cause a different pair of pins to
be shorted.
Instead, I rely on the following:
With the key in the run position but the engine is not running,
both the brake fail lamp and the low oil pressure lamp should come on at
1/2 brightness. Start the engine - both lamps should extinguish when the
oil pressure registers on the pressure gauge. Shut off the engine, you
should hear a distinct click from the run on valve about 1 to 2 seconds
after the engine stops.
If this does not happen, start trouble shooting. In my
experience the oil switch itself is the most likely culprit. I am on my
third one in 3 years. They seem to drop like flies - I think it is
because there is no protection for the internal switch from the
inductive kick back as the solenoid operates - but they could just be
crappy switches.

Subject: [6pack] 3 Wire Oil Pressure Switch Help
I was wondering how the 3 wire oil pressure switch is wired. I have two
straight up and down blades and one flat, looks like this l_l . I have a
black
wire that has the connector insulated , a white w/brn stripe and a white
with
what looks like a blue stripe. I'm pretty sure the black goes on the
bottom
flat blade but I'm not sure. My mechanic hooked it up but after he
played with
it my car alarm started chirping every few minutes and my alternator
light
doesn't come on when I turn the key to on anymore. Any help would be
much
appreciated.
Nick
PS I don't have continuity on any of the blades when the car if off.
Don't
know if that's the way it should be, seems I should have closed contacts
when
the car is not running.
