It is not a current problem. This circuit works fine when hard wired. It is only when the circuits switch is added to the circuit, that everything goes haywire.
Also, with the switch in the circuit and switched to the "on" position, prior to turning on the external power supply...
I'm using an external power supply to provide 24vdc to a GPS circuit. I am also supplying the same 24vdc to an LM317 being used to reduce the voltage to 15vdc to drive a small fan and a LED(with limiting resistor). The GPS circuit is disconnected and the fan disconnected. During checkout the...
