Increase 7.5 A to 10A

I don't know much about electricity so if this is a dumb ...... sorry.

Can I increase my fuse to 10A from 7.5A on my 08RK since I have blown the 7.5A a few times?

I don't think it is shorting out as it happens periodically not immediately.

I think my GPS and phone charger is pulling too many AMPS.

I am referring to the fuse that is inline with the pigtail that is connected to the battery.

Thanks in advance!

you can , but it will not be a good idea. the fuse is supposed to be the weak link, you increase the amperage of the fuse , you very well may cause a wire to overheat and possibly catch fire. When you say it happen periodically it sounds more like a short than an overload , as an overload would do it regularly , possibly you have a pinched/chafed wire that only shorts when you hit a bump or turn a certain direction etc. a lot of time if you look at the fuse after it has blown ,a direct short will show up at an almost explosive opening in the wire in the fuse blackened and or ***** of melted metal (similar to solder ) of the fuse wire inside the plastic or glass , where an overload will show the wire separated but often without the smoked area or solder *****. but increasing the size of the fuse is asking for a disaster either way. Another thought I had was if the fuse blows immediately when you plug in gps and charger, and you do not have a short, you could use what is called a slow blow fuse in the correct amperage, this is able to absorb the amp surge when you plug in an accessory yet still offer protection against overloads.

Bob has hit the nail on the head, it would be most unwise to use a higher rated fuse. I can't believe that your gps and phone are taking too much power, it is more likely there is a problem in that circuit. Have you added wires to plug into that pigtail? Try removing them. If the fuse still blows, then check the pigtail itself and chase it back to source, for damage, a poor connector, etc.
