Why does my headlight fuse keep blowing?

Headlight Fuse Keeps Blowing Out Make sure you have purchased the correct wattage of bulb. Ensure that you do not have a faulty or damaged bulb. Check and see if your high beam bulb is the issue. If so, replace it.

What would cause a headlight to keep burning out?

Any signs of condensation inside the headlight housing may indicate that water is leaking into the housing. Water and electricity don’t mix and any condensation may cause a short circuit leading to failure. Also, any condensation coming in contact with a hot bulb may cause the bulb to break.

What does it mean when your fuse keeps blowing?

V is voltage which is 12 volts. I is the current, which is limited by the fuse: let’s say it’s 10 Amps. Solving for R, we get R=V/I, or 1.2 Ohms. What that means is the resistance of the circuit has to be AT LEAST 1.2 Ohms. If it’s LESS than 1.2, then I will be GREATER than 10A, and you will blow your fuse.

What to do if your ignition switch fuse keeps blowing?

A simple trick to finding a short is to replace the blown fuse with a pair of spade terminals, then use small jumper wires to connect them to a twelve volt light bulb. A brake light bulb works well.

Why do fuses blow or how to find Phantom drains?

Phantom drains are key off illegal current flows. over about 0.050 amps. A car stalls and the battery is dead, running, is a failing charge system. The techniques for finding phantoms drains and dead shorts are the same, use an Ammeter and pull fuses, with a valid schematic in your hand.

Why does a hair dryer fuse blow out?

The battery can produce 500 amps. (over 5000 watts of energy) or 6.7 Horse Power of pure energy. Or 50 times , 100watt light bulbs. (or 3 hair dryers) The Fuse prevents the fire , by interrupting this faulting path. It can protect the igniton switch from blowing out, and the $300 combo switch melt down. Do not increase fuse sizes (ratings)

What should the ohms be on my Fuse?

Your meter should be set to read ohms. Touch the test leads together as a reference- on most meters this will register around 0.9 ohms. Then you would take one lead and touch it to the battery end of the wire; then touch the other lead to the light bulb end of the wire. If the continuity is good, your meter should now be reading 0.9 ohms.

What should my Fuse reading be on my motorcycle?

Really all you are checking is that the wire connecting the battery and light bulb is in good condition. Your meter should be set to read ohms. Touch the test leads together as a reference- on most meters this will register around 0.9 ohms.

Do you need a multimeter if your fuse keeps blowing?

It may be a silly thing to do but sometimes it’s easy to do these things without thinking. If you’re positive the right fuse is installed and the wires aren’t crossed, then you’re going to have to chase the circuit. You’re going to need a multimeter to do so.
