How to install a power relay for accessories. Adding heated grips.

In this video I detail how to install a common automotive, 12 volt, relay to control the power to your accessories. I installed Oxford Heated grips and I wanted them completely switched off when I turned off my bike. I walk through the steps of the install triggering the relay from a power lead when the bike powers up and how to wire in the accessories. Below are the links to the products I used in this installation. These are affiliate links to make it easier to find what I used.

The manual reports the stator is rated to 230 watts. It does not report the operating wattage of the bike, however the manual says that the accessory port under the headlight is rated at 15 amps. This says to me there is at least 15 amps of free power that can be used. My heated grips and heated jacket at full fused amperage would operate at 12 amps. I believe I am operating within the load capacity of the stator. The rating can be found on page 253 of English manual.

I'm a bit confused why the power of the stator is relevant, as the relay will only be drawing milliamps on the ignition side, the other side you have connected straight to the battery, no? Which is what Oxford say to do anyways, Lead batteries being able to supply a lot of current.

@@AsyncVoid True but over an entire day of riding with heated gear and heated grips if the stator isn't producing enough power the battery will begin to drain in order to keep everything powered. If the power draw exceeds the stator output then the battery will be drained. Maybe not completely but it will be drained over time.

@@advmatt I see, and because the stator is running the grips won't sense the lower voltage and cut off, make sense! Thanks for explaining

Thanks for the wiring diagram. I've also added the oxford grips, warm and safe jacket and auxbeam 6 function pod lights. Wasn't to worried about the grip heaters but wanted to have the lights turn off with the ignition. Ended up with something close to your diagram. The information on the stator is also one I'm interested in. Really enjoy your videos.

Glad you found the diagram helpful. I will post anything I can learn about the stator. Cheers.

Very cool. Thank you for sharing. I have bought my 390 last December, and many parts have been/are coming over to be installed. I'm looking forward taking my bike on BDRs. I really appreciate your channel for so much great info (especially) for KTM 390 Adventure community. I was able to sale the bike purchase, but will need to figure out how to sale the upgrades :). Perhaps I will see you on the trail

I used the same butt connectors for my Campervan wiring, and with a heat gun they will tighten up well. That said, I always do as you suggested here, and use the heat shrink tubing it's far more durable to abrasion. And a pack can be had for $5. - Frank

I put Apollo heated grips on mine, but wired directly into the switched accessory wire under the seat with no problems. I’m going to put in some Aux lights this winter, but I’m not sure if I’ll go the behind the headlight switched aux with a relay, or piggyback off the rear that I’m already using for the grips. Taking headlight off looks like a lot of work.

@advmatt Жыл бұрын

There is a small access panel under the headlight to get to the auxiliary power leads. I am just now sure how you will run the wires from headlight. As you suggest you might have to do a big disassembly. Be careful not to overload the auxiliary power leads with too many accessories. I think it is only rated for five amps. It has been awhile since I looked at the manual but that is what I remember.

Nice vid. Electrical stuff is not my strong suit but could you not have wired the grips directly to the switched factory accessorry plugs? I guess I don't see what the relay gets you beyond the factory plugs?

@advmatt Жыл бұрын

I don't know the load rating for the factory switched contacts. If the load rating is less then what is needed for the grips the circuit would trip. I didn't want a large current running through the factory switched contacts so using a relay keeps the load off of the factory circuit.

It’s frustrating they don’t just have the accessory wires already connected to the ignition switch… who needs accessory wires that are just hot all the time? It’s the simplest thing in the world to just hook up some wires to your battery, it’s the ignition switched accessories everyone needs/wants and has no idea what to tap into.

Do the Oxford grips fit on your new bars? As I remember they were a larger diameter than the stock bars.

@advmatt Жыл бұрын

Yes, the video will be out next week. The diameter of the bar at the grips stays the same, the change in size occurs at the clamp.

I'm so confused. I thought the relay is supposed to be connected to the battery, and then the grips to the relay???

@advmatt 9 ай бұрын

The relay has two circuits in it. One circuit for the power to grips from the battery. The second circuit is the one triggered when the bike is turned on. The trigger enables power from the battery to the grips by closing the relay contacts. I chose to switch the ground not the power side. It is all about how you complete the circuit. It doesn't matter where the relay is in the circuit.

@chucklesthefireguy5356 Жыл бұрын

I'm not understanding why the relay is needed. If you tap into the hot wire that's downstream of the ignition, it will always turn off when key is turned.

@advmatt Жыл бұрын

The relay keeps you from overloading the circuit you tap into. Ignition switched circuits have limited load capacity. Heated grips running at full heat can draw up to five amps or more. This could melt the wire you tapped into or overload the circuit burning out a fuse. A power relay protects the bikes original wiring circuits.
