This is a schematic diagram of auto fuse monitor circuit. This circuit is very useful for automobile application, checking a live fuse without wasting any electrical power if the fuse is working fine. This circuit can check the fuse? without removing the fuse from the working circuit. When the fuse is being tested, this fuse tester? is connected across it. If the either LED glows, the Fuse is blown. This testing can be done only if the circuit is live (powered). Here is the schematic diagram of the fuse monitor circuit:

This is a Blown Fuse Indicator Circuit With LED, its very useful when you need to know a fuse has been blown. Its very simple and as well as very cheap like my all other projects. It can be used in multiple places like home/car/bike just put it where you need to monitor a fuse condition. Whenever a fuse goes out the LED lights up and let you know,the fuse has been blown. In normal condition the LED remains off all the time. Make it in a good quality pcb and enjoy
