Hi all,
congrats on a great forum.
A quick question.
I'm trying to wire my relay to be triggered by the oil pressure sensor, but the voltage seems to work the wrong way around to trigger my relay.
I have tapped into the sensor wire, but when I test it with my multimeter, it shows 12v when the ignition is on, but when the motor is started, the voltage drops to 0v. (switching off the oil light on my dashboard)
Clearly this will only then produce gas when the ignition is on, and production stops when the motor is started.
How can I reverse the polarity of this signal so it will trigger my relay???
Sorry if this is a basic question, I'm confused about it.
Thanks for you quick reply :)
