Re: Relay Aliases Backwards
I have had the same problem. However, I dont believe the aliases are wrong but rather the LEDs are incorrect. Red now means the M+ is at 12v (M- gnd) and Green means M- is at 12V (M+ gnd). I say this beacause I am using a single solenoid which is spring return, so I only power M+, which the red wire of the solenoid is hooked up to. I simply toggle that relay's fwd bit to operate the solenoid and it works. I would not go changing the polarity of your compressor because reverse polarity could seriously damage it.
