Hey guys, I was wondering if any of you know how to build a circuit similar of that in vehicles that measure voltage from the battery and alternator to trip the charge light.
The circuit works by measuring voltage at the alternator; if voltage is less at the alt. then of that at the battery (such as vehicle off, ignition run) the light would come on. (12volts at battery, 0 at Alt)
The light would then shut off when the voltage at the alt met or exceeded the voltage at the battery. (12volts at battery, 13.6 at alt)
Anyone out there know how to wire something up like this?
Thanks alot.
Harry
