Hi Im new to the site and have a specific circuit in mind. Forgive me it its been covered already.
Im looking for a simple circuit that is able to monitor low voltage DC and trigger a warning light if the voltage is to low.
It will be used basically as a "dummy" light to indicate if a cars alternator is working or not.
So.... It looks at the cars voltage and if its below 12.5 volts it turns on a red LED. Once it goes above 12.5 volts the red Led goes off or changes the LED to green.
Anyway I realize cars already have this. But Im looking to do this to a classic car that came stock with an amp gauge. I dont want to replace the amp gauge with a voltage gauge and ruin the look of it. However it would be nice to know that the alternator is working properly.
Im also interested in some sort of voltage meter that looks like it belongs in an old car. This is for another project.
Once again thanks for your help, and great forum.
