Default Jump Start The Bike From The Tender Connection

I know you guys have probably covered this before - just wanted to ask.

I have a 2014 Ultra Limited. Original battery and all is well - but I think I will get a new battery next riding season. Battery still starts the bike - but, I was wondering is you can jump the battery from the tenders.

Bike has a tender - and, I have a set of alligator clips that also came with my tender. I cut those - and reversed the wires so I could have positive to positive and neg to neg. Just looking at the wires, it appeared that this is what I needed to do.

So, if I am correct, then if I have to hoop up a jump start to the bike, will these wires be sufficient.

Wish I could go to the battery - but, as I understand, getting to the battery looks like a lot of work.

Any other suggestions would be appreciated.

I've read on these forums several times that jumping may cause issues with the stator and voltage regulator. Plus, the tender wires are not a heavy enough gauge wire to be using as a jumper.

The current draw would blow the 10amp fuse.

I just reread your post, what texguy said. You need thick cables to Handle the current draw.

You can hook two bikes with a jumper between your tender plugs and allow it to charge a bit and start a bike. Done it a few times. You can also use a charger on low amp setting. The key is to allow it to charge the dead one up.
A weak battery can damage you charging system.

Thanks guys - I wasn't sure. I have a bike/car jumper - but, as I said, it is difficult to get to the battery on these bikes.

I am open to other suggestions. Have considered the charger that goes to the cig lighter.

I kept the battery in my 04 for 7 years - never had a problem. Went to a 2011 - but only had that bike for 3 years - then got the 2014. Still no problems. I am just playing "what if"/ Probably why I will invest in a new battery for the new riding season.

I do keep my battery on a tender if not riding over a week or so.

If you need to jump the bike, do it from the starter. Hot post on the starter (under a boot) and then frame ground.

Just a few seconds on the tender wires will start to melt the insulation.

We've used a Lithium jump pack before via the tender port. Not to really "jump" the bike as that requires a high current draw, but to do a quick charge. Plugged it in for 15 minutes then unplugged it and that was enough to crank the bike over.
