Pls help if you can
I have a secondary output on my car alarm system when activated with the remote i give a (200mA) 12v negative output. (ie volt meter +ve probe conected to 12v +ve and the -ve probe conected to the output on the alarm when activated the volt meter shows 12v)
How ever i made a mistake and have damaged the output by over loading it
It now shows 0.44v on the volt meter.
I need help with a simple circuit which can take the 0.44v negative output from the alarm and operate a relay. so that i can continue to use the alarms output
pls help
