How to determine the correct fuse for your head unit if you do not know the correct amplitude of the fuse how to calculate?
You would need to know the weakest point in the power distribution and you'd need to know the peak and nominal current draw in Amperes. If it's a device that uses a surge of current at startup but only a fraction of that during normal operation, you would need a "slow-blow" fuse. If the current draw is consistent you would need a conventional fuse. Still have no idea what the "head unit" is that you're trying to fuse.

What is the correct formula to calculate a fuse rating?
watts Divided by Volts = amps
How can you determine if a fuse is blown?
To determine if a fuse is blown, visually inspect the fuse for a break in the metal strip inside. If the metal strip is broken, the fuse is blown and needs to be replaced.
How can you determine if an AC fuse is blown?
To determine if an AC fuse is blown, visually inspect the fuse for a break in the metal filament inside. Additionally, use a multimeter to test for continuity across the fuse. If there is no continuity, the fuse is likely blown and needs to be replaced.
How can you determine if a fuse is blown in a circuit breaker?
To determine if a fuse is blown in a circuit breaker, visually inspect the fuse for a broken filament or discoloration. Additionally, use a multimeter to test for continuity across the fuse. If there is no continuity, the fuse is likely blown and needs to be replaced.

How can you determine if a bus fuse is blown?
To determine if a bus fuse is blown, visually inspect the fuse for a break in the metal filament inside. If the filament is broken, the fuse is blown and needs to be replaced. Additionally, you can use a multimeter to test the continuity of the fuse to confirm if it is functioning properly.
How do you install horn relay on 2009 Honda Civic?
The relay just plugs into the fuse/relay box, installing it means reading the owners manual to determine the correct location and plugging it in.
How can I determine if a fuse is blown in my house?
To determine if a fuse is blown in your house, first locate the fuse box. Check the fuses to see if any are discolored, melted, or have a broken filament. If you find a fuse that looks damaged, it is likely blown and needs to be replaced.

Which fuse is correct on for duel pump relay for 1999 cadillic catra
Can you use 20 watts or 30 watts in a fuse?
No, watts are a measure of power while fuses are rated in amperes (amps). To determine the fuse rating, you need to calculate the current in amps by dividing the power in watts by the voltage. Then, choose a fuse that is rated equal to or slightly higher than the calculated current in amps.
What would happen if you put a 3A fuse in for kettle which is 13A?
The fuse will blow as soon as you turn it on. Use the correct fuse and nothing else.
