FZ-1 Accessory Fuse Block for the Polaris Slingshot

    @D.W.Slusher What if there is no way of knowing the rating since this set was purchased through Amazon but shipped from China and if you have ever purchased anything from China you know that they rarely come with any paperwork

    Ok so who is next. Haters are gonna hate regardless

    I would say to start with a low rated fuse and use the trial and error method then. Your goal is to just make sure you use a fuse that will blow if there is a problem to protect the circuit and not become a fire hazard. You’ll probably be fine with like a 2 amp fuse. If it’s too low of a rating it’ll blow immediately, then try a higher rating until it doesn’t blow .

    Remember Folks, when you are using Switched Power, you are drawing current through the Main 50 Amp Fuse. If you install so many things that you are up to 49 amps while driving around, things are going to heat up, you want to be careful as you may not blow the 50 amp fuse, but heat will start melting the fuse holder and things can get bad under those condition. Use the formula of Watts to current posted above to get an idea of what you are adding to your Slingshot. Fused circuits are not designed to run at the rating of the fuse. It is mainly to protect the wiring from heating up to the point of a fire if there is a short in the circuit. Wire becomes a heating element when too much current flows. The fuse is to protect against fires! Circuits should always draw far less than the fuse they are rated. Remember, you can override the safety of a fused system by slowly connecting up high current draw accessories. You can not add to the full capacity of the fuse. Be careful When you inspect the battery for maintenance of connection is a good time to look at the main fuses for any signs of heat conditions, like the holder looks discolored or distorted. These are signs of heat and high current draw. Basic Electricity 101!

    Typically, I'd expect a fuse to be used on a circuit that consumes about 80% max of the fuse's rating, although a 50A fuse may see a little higher total expected load. Also, keep in mind that a fuse will not necessarily blow immediately at its rated value. A fuse will typically withstand minor, temporary over-current loads, with the likelihood of the fuse blowing increasing as the level of overload increases. Slow blow fuses are designed with an even higher tolerance before blowing. This doesn't mean you can safely place an even higher load on the fuse beyond 80% of its rating as the fuse is sized for 80% of the load the wire used for the circuit can safely carry. If the wire is nicked or flexed to the point of cracking, its maximum safe load will deteriorate.
    If you have run a separate power line from the battery to the fuse block and then use a relay trigger wire attached to a switched source, the relay shouldn't increase the load on the trigger circuit more than the 50-200 milliamps (.05-.2A) the relay needs to operate.
