And the solenoid air valve. Purty, chrome plated, and has a coil R of
about 2.1 ohms, no way I can switch that much 12 volts with a Mesa
7i76D. So that will take a booster relay, which I have.
You sure that isn't an AC valve? 2.1 Ohms would draw 5.7 A
at 12 V, and 69 W power dissipation. Can't possibly
tolerate that for more than a few seconds! Maybe that is
desired for an air horn valve, but it will never work for
coolant control. Maybe you can use an R-C scheme to cut
applied voltage after giving time for the valve to open.
