Hi, I need to install a light on our rural fire service (bushfire) pump trailer that will only be able to be turned on when the motor is running. So as it won't drain the battery if left on.
Could anyone offer a solution?
One thought was to use a voltage switch connected to the battery and when the voltage dropped below 12v (or whatever) it would open the circuit. If there is such a thing.
Any help would be appreciated, it's been a while since electronic studies...
Cheers,
Ian
