I found a good place to get the 12.6 VDC from. The red wire under the USB connector is 12.6 VDC and is good for up to ten amps with the stock fuse<F6>. It is shared with the heated grips that I do not have. The connectors are very easy to remove from the USB.

But this will stay active while charging, which is what I want anyway.

I think I will also put in a louder dual  horn, using the stock horn wires for a horn relay coil and use the USB 12 vdc input to run the louder horn. I just need to find a place to mount them, as I did on my Zeros.

I use a mini fuse tap (see picture) to get power from the fuse box. The fuse tap has a fuse for the power you are taking out, so it will not short your bikes fuse if there is an unintentional ground. You plug the existing bike fuse into the tap and plug the tap into the fuse box. It works great.

I have many of those thingies here. Perhaps they clear the seat on your Ego, but they won't on my SS9. At least it doesn't look like they will, I never even tried because the fuses are just below the seat and looks like there is no clearance for one of the fuse taps.

I wanted to wire in a plug for a heated jacket liner. Sounds like the red wire under the USB plug is the way to go... then run a power line back towards the seat area. We are within 10 amps (6-7 amps).

Yep, and I am also going to use that to run a horn. I will be working on that in a few minutes. I am going to mount the dual horns on the headlight bracket. One on each side. I have blue horns on order, but I will use red for now. The old horn wires will be used to active the relay coil.

I have a 2020 Ego. The fuse box is on the right side of the bike under the carbon fiber side panel. So I can at least recommend the adapter for other Egos.

Yep. I have all my 12 volt work completed now anyway, by tapping into the 12 VDC power that goes to the 5VDC USB. That should be good for up to ten amps.

My SS9 fuse box is right in front of the CCS socket and with the seat down, there is probably only a few tenths of an inch clearance.

What do you use for ground if you tap the fuse?

[DonTom]

What do you use for ground if you tap the fuse?

The low side of the headlight bulb.

Thanks.  That will work.

Nothing available at/near the fuse assembly?

[Specter]

With all this talk about finding 12 volts here or there.

The device that converts Main Battery voltage to the 12 volts.  What is IT's limit on amps total?   People want to add accessories, at what point do we overload the 12 volt bus?

Not in my two Zeros. I cannot say for other models.

Check the current. It can be checked right on the fuse and then see how much you can add to it. Use one of these thingies for the size blade fuse you have. The newer Zeros (2016+?) have some power to spare. They beefed up the DC2DCC around then.

awesome, thanks Don!

So to determine the capacity one has on their respective bike, they need to find the fuse and basically stay below that?

I'mma gonna git one of these and see where I CURRENTly sit at amp wise.

I've seen numerous 'Bike' gizmo's and gadgets that want 12 volt to run on, yet as we E bikers know, that's a rare number to find at times  !!

Yes, stay below the fuse value. The fuses are designed to blow below the current capacity of the wires to it. Sometimes just under, sometimes a lot under, depending on what circuits they are protecting by the fuse.


BTW, all the 5VDC USB outlets are fed with 12VDC underneath them. The stuff in the USB outlet itself lowers the voltage to 5VDC.  IMO, this is really extra stupid for many reasons. Even my new 2022 RV came with dozens of USBs not even one 12- Volt outlet. So how do you run a 12-volt GPS?


If they had 12V outlets, then you can buy a 5VDC plugin USB adapter for less than $1.50 US each. Then you have your choice of 12V or 5VDC USB from each outlet. I removed every USB outlet in my RV and replaced every one of them with a 12-Volt outlet. So now I can use either.


The bottom of the USB outlet on the Energicas are fed with 12-Volts. Much more useful than the USB. If you convert USB to 12V then you lost most of the current capacity that the outlet is fed with.


I wish all vehicle manufacturers would STOP installing those useless USB outlets and put a 12V in its place. Those who want USB there can buy the adapter for $1.25 at a Dollar Store.
