Constant power for gauges?
Hi forum
I'm installing AEM gauges. The boost gauge is being problematic. It powers up but doesn't display boost levels. I have checked the vacuum hose and it is flowing freely. The sending unit also checks out ok.
I have read that this problem *may* be fixed by powering the gauge from a 12V circuit that remains constant during cranking.
Apparently what happens is the gauge resets during cranking, so it doesn't calibrate for the vacuum it's receiving.
Where can I find a 12V circuit that isn't interrupted by cranking, but will shut off when the ignition is turned off? Obviously I don't want my gauge to be on all the time; it'll drain the battery AND look stupid doing it.
