Yes. The rating of a relay is how much current it can switch on and off, not how much it uses or must have.
Use the correct fuse and nothing else.
A fuse is a safety device which is designed to blow (fuse) if a larger current than it is rated for passes through it. So a 10 amp fuse can pass anything up to 10 amps.
Depends on the size of the fuse.
yes
absolutely not
In the UK, you cannot put a 5 amp fuse in a 3 amp plug. The general rule of thumb is that you should use like for like.
The Horn uses the same fuse as the Cig lighter plug. It is a 15 amp fuse.
Number 13 uses 10 AMP fuse
A 1997 Cavalier uses a 15 amp fuse for the cigarette lighter / horn. The fuse box door has a diagram that will show you where the fuse belongs and the proper amperage.
The difference between fuses is the current that they are designed to support. A fuse is intended as a safety measure to protect against overload. A 3 amp fuse should burn out if more than 3 amps is run through it, with some allowance for standard variance. A 13 amp fuse would burn out with greater than 13 amps. It is always a bad idea to use a fuse bigger than you need, because if your component is designed for a 3 amp fuse and you use a 13 amp fuse, there is a good chance you could damage your component with too much amperage because the fuse would not burn out at 3 amps, as was intended.
Yes. You put a bigger fuse and you will melt the wire and cause a fire hazard.
fuse number 1 is 10 amp fuse 2 is 25 amp fuse 3is 25 amp fuse 4 is a spare fuse 5 is 10 amp fuse 6 is a spare fuse 7 is 20 amp fuse 8 is 25 amp fuse 9 is 20 amp fuse 10 is 5 amp fuse 11 is 5 amp fuse 12 is a spare fuse 13 is 5 amp fuse 14 is 15 amp
Fuse # 3 - 25 amp - interior fuse panel
13 Amp My Iron uses this and I learnt this from AS physics on a task sheet
If you do that the likelihood is that you will blow the 3A fuse quickly. There is a reason why the current fuse is what it is, because it is expecting currents around 80% of 13 A or around 10 A.
A 3 amp fuse sounds pretty small for that application. I would suggest at least a 5 amp, and probably a 10 amp.
