What happens if a battery fuse blows?
Since the negative terminal of the battery is normally considered "Ground" or "Zero Volts", a fuse in the negative lead would leave the rest of the circuit "hot" - usually Not a Good Thing. Recommended practice is to place the fuse near the positive terminal of the battery, so the whole circuit will be dead if the fuse blows.
How do fuses work on a car?
Figure 1c is the way most vehicles are wired with a negative connection to the chassis. The fuses are placed in the positive lines from the battery and close to the battery. If a fault occurs on the line between the fuse and the load the fuse blows and current flow stops.
