A short circuit happens suddenly and the results can be devastating: sparks, fire, circuits tripped. It may seem like an insurmountable task to find and fix a short circuit. But with enough patient detective work and a good home tool kit, most homeowners can identify the cause of the short circuit and possibly even fix the short circuit.
The fix is simple, check the rating of the circuit and use the appropriate fuse. While using a fuse that''s too small isn''t going to risk damage to the circuits, the reverse is not true. Using a fuse amp that exceeds the rated spec for that circuit will cause damage and is a fire risk should the circuit develop a short. Locating a Short

Steve Grodt''s white paper from Chroma Systems Solutions [4] shows that the temperature versus time graph is very dependent on the type of short-circuit within the cell.. The worst case is shown to be for the aluminium current collector to the graphite anode. This could be caused by a foreign particle in the cathode layer or by a burr on the …
A short circuit – A short circuit can cause a parasitic draw by allowing current to flow through an unintended path. A stuck relay – A stuck relay may continue to draw power even when the ignition is turned off. A parasitic draw can be harmful to the vehicle''s battery and may cause it to go dead if it is not addressed.
The prospective short-circuit current (PSCC) is the maximum current that can flow through a shorted electrical circuit. PSCC is also known as available fault current or short-circuit making current. As with any current it conforms to Ohm''s law. Therefore, the circuit''s supply voltage and its impedance determine the PSCC value.
A 12-volt circuit is usually connected to a battery or a transformer. Because the voltage is relatively low, it is safe to troubleshoot if there is a short circuit without taking any extreme precautions. A circuit has to be complete for any electrical device to operate, so if you find your device is not working, there may be a short circuit.
