Here's this "EC5" to SAE adapter at 10 gauge. Next to it is the standard 16, I think, sae gauge. And you can get extentions in the 10 gauge. If the battery is too low then I use the stock alligator clips directly to battery as I've been doing. I'm just thinking! So what if melt a cable? The best education is experience

If the cable is too small you loose energy heating up the cable leaving less to try starting the engine

Yes, the last thing you want is an electrical fire lighting up some battery vapor or a few drops of gas that haven't evaporated on their own yet.

Entire garages are lost that way every now and then.

Many people receive invaluable education by being told something, like "cleaning a loaded firearm is dangerous, never do it." Not everyone manages to learn from experience. Not every experience blesses you with the opportunity to learn from it.

I admire your perseverance.

For others who might read this in the future and not understand the risks you have rightfully chosen to accept I leave the recommendation to read and follow the manufacture's directions for safe use.

Alan, I can't believed you just Pence'd me like that

I would love to have fixed my charging issue. And usually I end up fixing my issues somehow. But this one stumped me and I'm just getting by atm, albeit a bit to creatively than you guys are comfortable with, but gotta make do

What about INCREASE the size of the wire, because essentially I'm using a product of smaller wire to attach to a jump source of larger wire, which is the case no matter where you're getting your jump start from as all batteries have thick wire no? Just learning here.

And so far it worked fine. If down the road, literally, my jump starting needs become greater I'll monitor how the wires hold up, I'll keep my helmet on for dear life, and if my adapter burns up I'll still live I think.

The big point is if the charging system and battery are in good order you dont need to jumpstart the system, you are fixing a sympton not a fault

+1 to bryanj's words.

Ben, there is no "essentially."

You are using a product that is designed to jump start a battery using short, 6-8", 10 AWG wires protected by a short circuit/over-temp sensing safety device, connected directly to the battery. There are reasons that the leads are so short on every portable jump starter of this type. There are reasons that the manufacture's instructions clearly state to remove the clips IMMEDIATELY after the vehicle has started.

In your setup you have: Jump Pack => ~4" x 10 AWG adapter => ~3' x 12 AWG (that's smaller than 10 AWG, btw) => Bike Battery. You noted that the wires were getting warm, hopefully you understand why they are getting warm.

Hooking a trickle charger plug to a 1000 amp jump pack is like hooking your garden hose to a fire engine pumper truck. Lots of pressure until it fails. 

This setup is something that everyone else in the current conversation has warned you not to do. That being said, it looks like you have a personal need to move forward with this setup.

Back to the initial question/focus of this thread. With your current setup, where is the proper location for you to place a fuse for the new power source that you are attaching to your motorcycle in case your (+) ends up shorting to ground?

Back to the initial question/focus of this thread. With your current setup, where is the proper location for you to place a fuse for the new power source that you are attaching to your motorcycle in case your (+) ends up shorting to ground?

The "eklipse" jump starter/charger is both and I'm using the wiring for the jump starter which is designed to receive current directly from a battery, which granted mine isn't exactly what the intended use was for but both my jump starter pack and another vehicle function similarly in this case I figure, otherwise a vehicle would function stronger than my battery pack. So that's how I'm thinking of it. It's temporary. 8 know I'm just using a band aid.

Not sure what you asked after. I've shorted the fuse to either/or accessories pigtail or trickle charger pigtail. Not sure why. Sometimes my positive cable extension has nicked the engine while I've handled it. They're both under the side panel. Maybe that has blown one of these little fuses. I'm not too concerned as I wasn't paying too close attention as I am now as to what's going electrically on my bike

***Putting the "dad hat" back on.*** <):-)

Ben, I tracked down a thread on the AfricaTwin Forum that appears to be what you referenced earlier: https://www.africatwinforum.com/threads/eklipes-bike-2-bike-plug-in-jump-start.34481/

That thread turned into a very similar "debate" to this one. The big difference is that the "Discussion Starter" there was not modifying products/wiring setups to suit their desires. And, they appeared to understand what they were doing.

Please recognize that you started this thread with questions (2.5 amp jump starter(?), blown 10 amp fuses, using a 30 amp fuse instead) that clearly indicated you were not sure what you were doing. Great. That is one thing forums are excellent for, the knowledge of the few becomes the knowledge of the many.

We have attempted to give you guidance, which by posing a question you indicate you want/need, only to see you plow head-on on towards your own desired end with no apparent regard for the information that is been shared with you.

There are places on the internet where people get bent out of shape and turn very sour towards one another. Luckily, SOHC/4 Owners Club Forums is not one of those places. Just look at how many people have spoken up to try to protect you and your bike.

Consider your agenda before asking questions. Be as clear as possible about your end goal. I imagine this conversation could have been a whole lot easier if 3 days ago the question was, "How do I setup easy access to high amp battery connections for jump starting? I don't have resources to fix my charging issues and I need this bike as my daily transportation. A portable jump starter is getting me by for now."

I am not saying that is exactly your case, and we each process information a little differently. You have admitted that for yourself.

I am asking you to help us, help you a bit easier. There is a big difference between seeking education and seeking validation. I guarantee that you will continue to find a lot of education on these forums. Validation will not always be provided, especially when it is not seen as healthy for a bike or owner.

***Removing the "dad hat" now.***

Yes, that's the thread.

Some times when people look for info/advice, they're just looking for info, not necessarily follow instructions. And it doesn't necessarily even mean they disagree with the advice but that they just go about figuring things out differently. Like I tend to go the "blowing s*** it up" route rather than the tried and true methods, following recipes/instructions etc. And it's costly and dangerous but also fun and sometimes rewarding when you discover new things not found found in the established methods. And ya'll can blame yourselves for picking on me when I was a kid so much you screwed up my mental wiring for social conformity lol.

But like I said, I do get valuable info from "ya'll" and am constantly learning despite my seemingly stupid hard headed methods. Just don't get your egos so involved when I don't follow your advice, cuz I can't do nothing about that. And truthfully if you've given me true and valuable info I'll get it, maybe not right away but down the road. I'm a slow learner, hence I don't take instructions. I have to process s*** completely my own. I trust no one... If we're gonna get all psychological about it. If I go down in flames I go down in flames. It might be my destiny. I'm sure I'll be fine though and you guys rock. And my bike likes me too!

So do you feel you are still learning something  here.
 Do you think your problem  got smaller, or even bigger ?
