What should I do if I find a short circuit in my car?
Follow the same divide and conquer method to determine the approximate location of the short circuit. Once you find the short circuit, then you can go about repairing it. Before reconnecting the battery or putting in a new fuse, recheck for short circuits with the test light or multimeter.
How is a short circuit different from an open circuit?
At its most basic, a short circuit is a fault in the wiring harness, which shunts electricity between circuits before getting to its destination. A short-circuit should not be confused with an open circuit, in which current does not flow at all. Though the symptoms of a short circuit can be similar to an open circuit, diagnosis is a bit different.
What does it mean when battery drain is slow?
A slow battery drain when everything is off is called a parasitic power loss. This happens when something – a glovebox light, an amplifier, any electrical component – is pulling power from the battery when it shouldn’t.
How much power does a radio clock drain?
A clock in the radio draws as little as 0.01 amps, whereas the combined interior lights can exceed 1 amp. That seems like a tiny amount, but a single incandescent dome light pulls enough power to drain a battery in one day.
