Fusing - madBeavis/PimpMyAtv GitHub Wiki

When doing a full build for ATVs using a proper psu, fusing very seems reasonable considering the investment of time and equipment one wants to keep ones hard work safe. Several accomplished builders have used distribution/fuse blocks, with one of them even saving several of their devices. As with other aspects of doing proper builds, do it once and do it right, so be prudent and include fusing.

Since we are repurposing fuse blocks from automotive and marine applications, many configurations are available. Do shop around from various sources, as the prices differ, even between products that are ostensibly the same product just sold under a different brand. A few sample products are as follows:

1. 12x block
2. 12x block strip
3. 6x block

Compare the tidiness of the fuse/distro block compared to strips. Nevermind that they don't provide any protection via fusing. A tidier and simpler setup that also provides safety for ATVs, just skip over these.

Even though many of the blocks come with fuses, it is often a variety and not suitable for our purposes. I run 2amp fuses in all my blocks, as 1amp would be right at the startup current draw of many ATVs and anything bigger, such as 10amp, isn't responsible.

Most of us run one fuse per ATV, a couple have run multiple ATVs per fuse. For the 32 relay numato, this requires 3x 12 fuse blocks. So you have four left over after fusing the ATVs individually. I used one for the relay board and the remainder for fans. If you are short of funds/space, one could run two ATV per fuse, just know that it isn't as safe as individual fusing. No one wants the first fire award, so I would recommend using 1 fuse per ATV. If doing a big build, we are talking thousands of dollars of equipment and the time to design and install, might as well do it as right as one can the first time.
