I've added lots to my bike from the battery such as:

alarm feed,
optimate feed,
air horn feed,
hot grips feed,
12v socket feed,

each with inline fuses.

Problem is as you can imagine, I've now 5 wires coming off the batter terminals and its looking messy!

I'm wanting now to hard wire some cameras to the bike too.

How have you guys done similar or are there any products out there which may help?

Thanks

Added benefit, prevents forgetting to switch something off from flattening the battery. Wire it up so that coming off from each fuse a tail with a bullet connector.

Would the relay be for letting the battery live through when switched through the relay by the ignition?

Thanks I'll check this out Karma Thumbs Up

Yep, the relay is wired between the battery + and fuses with an ignition live and earth to either the battery or frame. It is an automatic switch Thumbs Up

I use one on the heated grips so I can't forget to turn them off.


A really good place to get an ignition live is the rear brake light switch, you just need a test light to find out which of the 2 wires is the power and which goes off to the bulb (you don't want it only working when you've got the back brake on) If you cut into the wire then do it on the wire between the switch and connector so the main wiring loom stays untouched.

Hi

Looks like a good solution, but remember not to wire up the Optimate through the relay.

All the best

Never really understood how the frame completes the circuit. The resistance must be massive.

Why doesn't it drain the battery?

Kind of like when you connect a battery to a piece of metal. It heats the metal and discharges the battery.

You could use on of these;

https://www.nippynormans.com/products/f650stcsgsdakar/item/fuzeblock-switchable-fuse-panel-fuz-fz1

It would certainly tidy things up but you could buy your own relay and bus bars and do it for less £ Thumbs Up

I will keep it in mind thanks for sharing the information.

Steel might not conduct as well as copper, but in a frame there is a massive amount of it. For a conductor, the resistance will be a based on the cross-sectional-area of the conductor, and the specific resistivity for the material.

It's like the difference between a pipe with a large bore and one with a small bore: the greater the area to flow the lower the resistance to the liquid.

Obviously you get "bad earths" when the connectors from the various electrical fittings get corroded where they bolt to the frame, which results in a high resistance and all manner of weirdness can happen.

Next time you have the multimeter out check it if you like, from pretty much any point of bare metal on the frame to the battery negative terminal shouldn't be more than a couple of ohms.
