Blowing fuses

[hath]

Hi guys, I recently wired in new Autometer gauges and a horn. Today while the truck was idling, I had the radio on, air compressors running (bagged truck), and when I pushed the horn, I blew the 3 amp fuse that runs some of my auxiliaries. Any suggestions? I was thinking of taking a few of those auxiliaries and running those from a different circuit. Or do I dare bump up to a 5 amp fuse? I definitely don't want to fry my new gauges!

How many things do you have running off of that circuit, and about how much power does each draw? I wouldn’t change the fuse out for a bigger one. Otherwise you risk overheating wires somewhere in that circuit and potentially starting a fire. If you need to, you might have to wire the high current draw devices on a new circuit with a dedicated fuse or fuses.

and maybe use a relay , or two.

Use a slow blow 4.
