What causes a fuse to keep blowing?
First, and most commonly, when too many lights or plug-in appliances draw power from the circuit, it can overload the capacity of the fuse and cause the metal ribbon inside the fuse to melt through. A mis-wired lamp, for example, can cause a short circuit and blown fuse if it is plugged into an outlet.
Why do boat fuses keep blowing?
The fuse blows because one of the accesories on the circuit is shorting or drawing too much, or the wire itself is shorting in the harness, remote box, or on the engine. The starter itself does not go through this fuse. It draws directly from the battery via the solonoid.
Where are my boat fuses?
Where is the fuse box on a pontoon boat? The location is typically underneath the seats or main console panel. If you have an older pontoon, it will resemble the fuse box in your home. On the boat, it could be a small box or a large assortment of wires.
Can I replace a fuse with a higher amp?
Never replace a blown fuse with a higher-amp fuse. Always replace the fuse with one with the specified amp rating. You may install the next-smaller-rated fuse to get you by in a pinch until you can purchase a replacement.
What should I do if my fuse keeps blowing?
The simple fix is often replacing the blown fuse and test the car again. If the fuse does not blow, it might be an easy fix because there was a power surge in the system.
What causes a circuit breaker to blow a fuse?
Any faulty wiring or connected parts risk a power fault (surge), which trips a circuit (or blows a fuse). So, again, the problem is not that the circuit breaker (or fuse) didn’t do its job but rather that there was faulty equipment.
Why does my thermostat keep blowing fuses?
Wear and tear of sun light, animals or weed eaters usually cause these shorts. I would like to suggest that you inspect the thermostat wires for cracks, wear and tear.
What happens to a fuse when it melts?
You will see that the fuse has melted, and there might be charring on the panel. A true fuse typically consists of a piece of metal, most commonly an encased wire, that actually melts when overheated. This is what stops the fault (aka “short” or “power surge” ). The destroyed fuse must then be replaced with a new one.
