I'm looking for suggestions on how and where to run a fused pigtail from the battery. I would use this to connect a trickle charger or to supply power for a tire pump, etc. If the battery was under the seat it would be straight forward - remove the seat and pull out the wire. I want the wire to be hidden and protected from the weather. Thanks for any help.
 
Pretty basic. Get an SAE plug that something like a battery tender uses and wire to the two leads of the battery that's under the right side of the fairing. If you want to run the line to under the seat, you could. Most just leave a little length hanging.

I'd look a the various mode pages at FJR-tips.org including this one: https://www.fjr-tips.org/mods/pdb/pdb.html

Also search on "pig tail" and see a variety of threads talk about them.
 
Keep wire size in mind when using a tire pump or other accessories that draw more than a couple amps. My '15 is set up with two Powerlet style plugs (near the seat lock) for higher power accessories and a standard SAE 'tender pigtail near the tank. When not in use, I stash the SAE lead between tank and battery cover.

What generation bike? Your options will vary with the tupperware. I have two weather-tight outlets on my Gen II. The one at the front is actually wired to a heat controller on the dash and is for my heated vest. It's also pretty tight behind the plastic -- correct placement was critical:

The one at the rear is fused to the battery. I use it for the battery tender but can also be used to supply power to a passenger vest or phone charger, etc. There was more room behind this spot:

I had similar outlets on my original Gen 1, but I don't have any pictures at hand. The front was on the black plastic panel just below the tank on the left. There was a lot more room on the Gen 1! The rear was simply a pigtail that I led out of the gap beneath the seat when it was required.

Your tire pump (compressor) will require a 15 Amp fuse. Your trickle charger (battery tender) won't care so much. I have had such a pigtail on my '06 and '08. The '06 was terminated in a Gerbing heated gear connector. That one required an adapter to go to an SAE quick connect for the compressor and battery tender. Cheap and simple. It went under the tank to the left side. The '08 is terminated with an SAE quick connect to go directly to either device. It comes out by the ABS on the right side. There are all kinds of places to run a pigtail and all kinds of ways to tuck them in.
 
I have a 2023 that I bought for my 72 birthday. Picked it up on the actual day! My thought was to use a SAE connector. I'm not comfortable with drilling holes in the tupperware for a connector. Too bad Yamaha did not wire in a higher current socket in the left box.
 
12" SAE, and bring it down from the battery, tucked behind the side fairing and it will simply pull out from one of the molded vent openings for easy access.
I have similar to this except I keep the end tucked into an adhesive backed cable holder thingy stuck to the frame rail. Hasn't moved in 3 years.
 
If you hope to use the SAE connector to jump start the bike, you may be disappointed at a time when you are short of other options. Wire is too small and the fuse too weak for most jump starts. (Ask me how I know!:LOL:)

For jump start options, either have tools and connectors to access and connect directly to battery or use heavy wire and fuse to have a more accessible point - such as under the seat.

Would love to hear of a less elaborate set up.
 
KISS whenever possible. See post #8. 12" lead comes our a fairing vent hole (when I need it). Invisible tucked in the fairing ...99% of the time.

Is the pigtail that came with my Deltran Battery Tender Jr. adequate to power my Slime tire inflator?

Is it the one with ring lugs at one end, an SAE connector at the other, and an inline fuse? As long as you replace the inline fuse with one that's adequate for the Slime Pump (probably 15 Amps), it's fine. The wire is heavy enough to handle the current. And you can still use the same pigtail to connect the Deltran and charge the battery.

^^ this, from experience with both examples, after replacing the fuse. I don't use heated gear so I have my pigtail pop out at the right corner of fuel tank and front fairing. I then ran it along with the throttle cables to the handlebars to use it for phone charging and volt meter.

Have a look at this...

This can be used with other Eastern Beaver power distribution accessories. Good stuff.
 
I have been working on a similar setup for my bike for the past couple of weeks, but this setup will work with a small jump starter instead which I will carry with me (and keep charged). The 10 AWG wire with the O-ring connector will be mounted to the battery, and the blue EC-5 connector will normally be plugged into the matching EC-5 male connector of the fused (7.5 Amp) Battery Tender lead.
In case of need, I can unplug the Battery Tender lead, and plug the female EC-5 connector from the battery directly into the jump starter. I still need to figure out the cable routing and accessible attachment points to the body for this setup.

I use a small electric pump recharged with usb port. Very small, very fast tyre inflation. Pre set pressure.
For. The trickle charger, just conect to the battery. Has weather sealed plug.
Just tucks in between the battery and the frame.
 
The specs on that one says 5 amps max. Sufficient for a battery tender but not for an air pump or to run heated gear (10-15 amps required for that). Unlike the Powerlink I referenced, it is nowhere near enough to "boost" start your bike. Perhaps you could fuse it at 10 or 15 amps so you could run an inflator or heated gear but I would want to have a look to make very sure that the wire gauge was sufficient for that much load - probably 14 ga needed.

Huh? My heated vests draw about 3 amps each at full toasty. Or are you specifically referencing the air pump since it is the highest draw?
