Hey Everyone!

Im doing a project on my car which requires the use of an electric oil pump. The pump has a fuse inline and is turned on with a relay. 12v will be used. I want to make a warning circuit so that if the fuse blows for the electric pump I will be notified by either a buzzer or a light turning on. It sounds really simple to me but I can not figure this one out. Any help I would really appreciate! Thanks.

 

We are iffy about cars and modifications. Could you say what the oil pump's function is?

 

Won't the oil pressure light that is already there give you a warning?

The pump is for a rear mounted turbocharger setup. It is a scavenge pump that when the oil comes out of the turbocharger this electric pump pushes it back up to the engine.

 

Consider just using a small 12v bulb connected across the fuse.
If the fuse blows, the bulb will light up.

 

Personaly I would use an Audio type indicator eg buzzer, lights tend to be missed in a vehicle. Generaly Ive found engines destroyed from lack of oil pressure due to the warning light beeing missed in daylight. Lack of oil dammage is fairly quick. Sgt Wookies idea across the fuse is the easiest way of doing it.

 

Thank you for your responses. I will do some experimenting with this idea and let you know how it goes.

 

Thought it might be for a James Bond oil slick device

 

Maybe on Hugo's.
