In line operational light help

Postby waynesworld » Tue Aug 20, 2013 1:15 am

Hi all.
I am trying to configure a circuit for a blower that has a small dash light that is lit up when the blower is switched on. (Light on-all systems fine) Hence if there was a problem the light would not be on. I thought this would be a simple in series circuit-like the xmas tree lights-one down all down. But now I'm trying to pull 4.5 amps through a tiny light. So if I go parallel then the blower could be "down" but the light could still go so defies the purpose. Through a relay will be the same as parallel?

I would love some ideas here because I cannot work this one out. I have two blowers & a bilge pump that I want to have an operation light for-that is one for each.

Thanks in advance

wire it up in parallel on the two wires that go to the blower motor but it still only shows you have power to the motor only way would be to use pressure transducer for bilge pump and perhaps fan driven generator for air (12v computer fan might produce enough current to run an led light)

Kind regards

the pressure transducer will read a change in pressure and activate a relay to turn on a light ,the computer fan will start spinning when the blower fan turns on and generate a current to turn on a light

Yeah Ok so it would show that there is current to the blower but not showing whether the blower was actually "running" or not?
I never thought of that.

Cheers mate

If you go parallel to the motor then only have the motors ground the light won't work if the motor doesn't.

I have LEDs at my switches. I don't remember for sure how I did it.

If you could imagime something like a ping=pong ball inside a vertical clear tube.
Airflow would raise the ping pong ball.
No wires, no transducers, no lights, no circuits.........
