Wireing a buggy? To fuse or not?

Should everything have its own fuse? I have only a few circuits. Fan and fuel pump fused. Then led lights and a few light circuits. Or can I use a fuse for the ignition circuit to protect the light weight stuff in case of accidental ground?

fuel pump and fan, at a minimum should have a relay. Each circuit needs to have a fuse as well, otherwise if there is an accidental ground it could fry the entire system.

Is there any need to use a fuse in a line that has a relay?

yes, fuse the 12V feed to the fuse....

A relay makes it where the switch is not picking up all the load at once. The relay does takes the abuse not switch. That is how I picture it working.

Awesome thanks guys

There are some 12v ignition sources. Like to the computer compressor and fan. Since these are low volt signal wire do they need a fuse? Or just the main power wires to them

No fuse required.

Speedway Motors makes some pretty cheap harnesses with many different number of circuits.

I had a 22 circuit universal for a jeep project and contemplated getting a 8 circuit for the buggy but since every system is stand alone and has its own fuses already except 4 of them I figured it would be easiest to do inline fuses.
