hi ya'all,
i want to design a circuit which will tell me in real-time what is the status of the radiator fan in my car (alive or dead).
i thought of placing a led in parallel to the fan but the problem with that is that the fan could be actually burned out while the led will still be on (it will still recieve 12v).
any suggestions?
mabe some kind of tachometer or any other simple sensor?
thanks for the replies
