Hey all, I've got an early 90s tractor with a charging detection circuit that the part is obsolete. So I figured I could make my own.
Here is a capture of the wiring diagram:
I've located a simple circuit that I thought might work:
I know this circuit shows the + switched and I need to make the - switched.
However, because of the hysterisis on the relay it does not deenergize the relay when the voltage falls below 12.6ish volts.
Outside of experimenting with higher voltage zeners would I be out of luck of building this without adding a transistor?
I really didnt want to add a project box and such to make this work.
Thanks in advance for any insight.
