LIGHTS LEFT ON WARNING BUZZER
This little buzzer will end the pain of a flat battery after leaving the lights on.
Here's how it works: When your lights are on they feed 12v + to terminal 2.
When your door is open, the door switch makes an earth connection to terminal 3.
If your ignition switch is on, the buzzer is silent but when you turn your ignition switch off
and the door is open the buzzer activates.
Three 1/4" male spade terminals.
Terminal 1 - 12v+ from ignition switch
Terminal 2 - 12v+ from side lights
Terminal 3 - through door courtesy switches to earth.
