Help with battery/flat battery issue

Postby bic_bicknell » Sun Oct 08, 2017 6:26 pm

Bit of advice urgently needed as I have a flat battery (again) and need to get to a meeting tomorrow urgently.

This is my relatively new battery I put in to replace the Shorai one and I confess I haven't ridden the Superduke for two weeks so it's in good order, just lost its punch due to non use and the alarm draining it over time. Bike is stored at my lock up where there is no power so I cannot just charge the battery up as I would if it was at home.

My usual option (which I have done a few times for various reasons) is to push the bastard the two miles to my house and then charge up over night. Because of the hard to access battery I have a trickle charge cable wired in with easy access under the tank. This is a Halfords maintenance charger as shown in the link below.

I'm shit with anything electrical (really a dunce) but I have had this thought which I need to ask about and many of you out there will be able to tell me if this idea is OK.

I really, don't want to push the bike two miles and neither do I really don't want to have to take off the belly-pan and remove the battery to get it home as I just don't have time tomorrow. So my question is can I just go to Halfords, buy a really cheap car battery - pre charged, and then use the cables from the maintenance charger to jump start the bike in the morning?

The maintenance kit comes with another cable that plugs into the lead with the same male/female connector. It has clips on the other end that are for when you just want to charge up a battery when it's not in a bike. So can I just reverse this cable and clip this onto my new charged battery, plug the connector into my bike lead under the tank and jump the bike? I started getting concerned because I can't work out whether I need to still clip the RED/positive clip to the positive terminal on the battery or whether I need to reverse this and clip the Black clip to the battery.

What will happen if I connect the new battery through the leads the wrong way round?

Will I permanently damage something and if so what?

Is it better to just cut the lead that I use coming from the transformer and wire this to the new battery? But even then I do not know which side of the lead (and more importantly male/female connector) is positive or negative.

Any help or comments appreciated!!

Thanks in advance.

Oh, another thing,

My charger has much thicker wires than the one shown in the link. They're quite beefy, not a thick as jump lead cable but way thicker than these.

As No.47 linked to.
Use your bikes' battery to power up the ECU & FI but connect the remote battery to the starter solenoid and to the starter motor chassis earth. That way the start motor will mainly be drawing from the remote battery.

Don't connect through the charger lead as it isn't man enough. It'll just blow the charge line fuse (if there is one) or get the wires very hot.

Ha ha!

I just found that out (blowing the fuse on the trickle charge lead) :oops:

Once that happened I realised that the bloody fuse is buried in the wiring underneath the belly pan so I was going to have to take that off anyways. So I decided to push the fooking bike the few miles home and just replace the fuse and use the trickle charger I have over night.

All done now and bike on charge outside the house but it cost me a wasted trip to Halfords, a wasted investment in a jump start kit, an hour long push through Bristol and a 60 unite strip down to replace a 10 amp fuse.

I fooking hate the KTM Superduke battery issue and what you have to do to fix the situation.

Of course I never had this problem over the last 11 years of ownership because I rode it every day. But now I don't and the problems start.

I don't ride it as much now because, to be honest, the Kawasaki 750 triple is far more fun so it gets all my attention now.

Bic,
HAve you thought of getting one of these ? https://www.amazon.com/FUSHITON-Portable-Starter-12000mAh-Flashlight-Yellow/dp/B01KUGT7QQ/ref=sr_1_20?s=automotive&ie=UTF8&qid=1507571213&sr=1-20&keywords=jump+starter

You can keep it charged at home, take it with you when you go to get the bike.

It's small and it packs a punch.
Ride Hard,

That would be my vote for a back up or emergency dead battery. Two months ago I watched a guy at a classic car cruise-in start his 1970 Plymouth Cuda 340 cubic inch V8 with one. I was talking to him and he wanted to start the engine and nothing, he goes to the glove box and pulls one out and I'm thinking I always wondered if they really work? Clips it to the battery and turned over and fired right up. :shock: :D I've been meaning to get one as I have several 440 cubic inch muscle cars that sit most times on a trickle charger but sometimes not.

Bic I still think you need to check for a discharge/draw in the system greater than the alarm. Especially since this dead battery issue you're experiencing just appeared in the last year or so, something has raised an ugly head.

Bic - just bought one of these - https://www.amazon.co.uk/DBPOWER-Portab ... B01MT1AACJ - appears to be best in class, well designed and comes as a neatly cased package as well.

+1 on the lithium battery pack to jump start the battery. I'm about to order one as well since I take my bike stupid places sometimes (my super enduro, not so much the super duke) and would like to knowledge that I can jump the bike on a cold morning if needed.

plus I can charge my phones, GPS, GoPro, etc. I have a small battery pack for travel but the new ones that will jump a car would be very very nice.

Just make sure you wire in an easy to access "port" for the battery and I think you'd be good to go. lightweight, no mess, and can jump your car if needed as well.

Was planning on connecting positive to starter motor positive if battery simply flat (sub-12V) enough to not be able to crank and start engine, or to starter relay positive if battery dead/not being charged thru’ reg/rec, and negative to frame to avoid having to get to battery - have asked DB Power if there are any reasons why this unit should not be so connected.
