The clicking noise usually is an indication of a discharged or failing battery. If you hear a grinding noise, then it might be due to a failing starter or a lousy flywheel ring gear.

Your car’s fuse box helps prevent overvoltage and short-circuiting. A fuse may blow out for no real reason in which case, you only need to replace it. But if you have a few fuses that keep blowing out repeatedly, your vehicle’s electrical system may need evaluation. If a fuse is blown, that’s a sign indicating one of the electrical devices inside your car or the wiring carries too much current. Replacing the fuse without identifying the problem beneath is not a long-term solution, as the fuse will continue to blow until the actual issue is fixed.

The life of your battery is most commonly affected by factors such as temperatures including extreme heat or freezing temperatures, and the length of your car trips. Regular short trips won’t allow your car’s battery to fully recharge and hence, that will shorten its life expectancy.

An electrical component could be getting shorted or you may have hot wires somewhere in your vehicle. If the wires get too hot, they’ll melt their plastic insulation and could ignite the engine.
