Hello,i have a customer which has sent me a warning indicator rpm monitor but it hasn't a lcd panel only 10 bulbs with the symbol of axle/sensors.Sensors consist with one 820Ω Resistor and an reed switch in series.
The principle of work is,when the axle achieves its working rpm then the bulb turn off
The problem i have now that one bulb is glow all time. We changed sensor and We test the circuit everything is ok and secondly i don't know how the bulb goes off with the reed switch.So,i need a help from the forum
Thank you
