What causes a fuse to blow in a motorcycle?

What causes a fuse to blow in a motorcycle?

Simply put, motorcycle fuses blow when there is higher current amperage than the circuit can handle. The fuse gets blown up because of any of these problems in the electric circuit. These failures in the circuit will make the fuse to blow up and as a result, the fuse removes the power from the faulty system.

Why does the main fuse blow and not a branch fuse?

A. Here are some reasons a main fuse (say 100A) blows instead of a branch fuse (rated at 15A, for instance): 1. The two fuses’ time current characteristics curves aren’t coordinated. This could be the case with dual-element, time delay, 15A fuse and renewable fusible element-type 100A fuse.

Why does my bus fuse keep blowing out?

You can see damaged fuses or loose, heated connections in a thermogram and make repairs. —J.F.F. A. With more than 40 years of experience in electrical maintenance and construction, I’ve learned loose and overheated main bus connections often cause such a main fuse problem. Frequently, this problem occurs where fuse blocks plug into the bus.

How many amps does a 100A fuse blow?

These can be as low as 2 to 1 (100A main versus 50A branch fuse = 2 to 1). But watch for old installations where connections have deteriorated and/or fuses have been in service for a long time.

Why does the fuse blow on a type’s Edison?

Edison and Type S fuse adapters can cause additional problems if the hot bus screw isn’t tight, causing heat to spread or “sink” up the main bus. I’ve experienced this many times. In some cases, the equipment was badly overheated. Upon tightening, it got better for a short time before overheating and failing again.

What should I do if my motorcycle fuse keeps blowing?

It’s a good idea to keep a spare main fuse on hand at all times because they can go at any time. If the fuse continues to blow, you will have to check other components of your electrical system to see what is causing the excessive amperage. Faulty wire grounds are a very common problem, but can sometimes be difficult to track down.

Why are the fuses blowing on my car?

Within the distributor itself, a bad or bypassed ballast resistor can repeatedly blow fuses, but that’s unlikely unless some hack mechanic did a bad wiring job on it. A bad coil might blow fuses, but it’ll more than likely kill the engine before that happens.
