Hi everyone, i am trying to come up with a circuit for my car,
i need a setup that will deliver a constant 12v for around 5 seconds once the unit stops recieving power,
it is for electronic gauges to go in my car which calibrate when they receive power. if connected to the ACC position (the one the stereo usually runs off) power is cut white starting the engine to give the starter motor as much power as possible, then the gagues re-calibrate when the engine is running, not returning to a true 0 position, and if i connect it to the ON position, it retains constant power but the gagues dim really bad as the starter motor draws a lot of current and this has the possibility of damaging my gauges,
thank you guys
