Battery or Something else?????

[Kang]

Hi, Bike would not start for my commute home last night so had to get a jump done.

Charged the battery (yusa) overnight 12hr, put it back on and she fired no problem this morning.
Now.....when I got on the bike to get the centre stand down and drive off the bike completely died????
Turned key on off (few times) and nothing, so had another look and did the mandatory little movement of the battery leads turned key and she fired no problem.
Got in to work and gave it two stop start tests and on the 2nd start it coughed a bit, so looks like I will be jumping for the home commute.

12v socket, heated grips (both being disconnected when I find out which wire is which) and a Flash tune kit also connected.

Im sure the battery is dying/dead (don't know how long its there) but it was the shut down that stumped me?

Get a meter on the battery;

• Check cold voltage. - minimum 12.5 v
• Check cranking voltage- minimum 10 v
• Check voltage at 4000 rpm - minimum 14 v.

Report back.

Make sure the battery leads/connections are clean and tight.


One day my bike didn't start - with a great deal of force I could just wiggle the positive battery lead. That was enough to start it. Got home and really cleaned the connections, no problems since.


But get the battery checked out anyway - if it looks old then it is probably time for a new one (I know this statement isn't very technical but if you rely on your bike as transport you've got to be sure it's going to start).

Turns out the charger I have is Knackered. Hooked it up to a borrowed (good one) and it read half full so charged it up and is running grand.
Also disconnected the grip warmers.

Thanks for the help.

I’d say there’s still an issue, knackered external charger is undesirable but not the cause of a cut out. Unless it was just a loose connection with those wires you wiggled.

Undo all the battery lead connections especially the Ground/Earth lead connection at the rear top of engine (1st picture), smear all the connections with Vaseline when doing them back up. If wiggling the leads got it turning over again then that would point to a poor connection.
The other one to pay special attention to is the far end of the positive battery lead, Just under the live battery connection, the lead is very short and easily missed.

I wish 600 owners, no matter how sincere, would stop posting advice on the 1000 forums based on their bikes, it is neither relevant nor helpful.

The picture may not be helpful but the guidance would be the same whatever bike it was

Not if the advice is based completely on the pictures
