09 KTM 530 wont crank with red button.......

[Wopper]

OK Im going to ask for some help here too, was out riding on the weekend on my 09 530, was halfway into the ride, shut down the bike and it wouldnt crank with the red button, just clicking from the starting solenoid. removed seat and checked battery terminals, all tight, checked the fuse, = OK, quick check on wiring looked OK.
Fired the bike by kicking - UGH - rode back without stopping.....
Shut down, it hadn't self fixed, hmmmmm.
So tonight, unload bike, remove seat, check battery voltage, reading 16 v.... still nothing with red button.
Connect charger on 70 a start , it will crank for a few seconds, turn over very slowly, then stop.
Still wont crank without battery charger, but all system appears OK.
I am thinking starter bearings or brushes tight???
Anyone else had this issue?
PS, bike has always been a happy starter, no issues with jetting or anything else like that, it just doesnt want to turn over with the red button.....any ideas???

16 volts is kinda high.
Bad VR overcharges battery ...starter calves from too high of a voltage....??
Sounds like a bad starter.
Kick start it and check the voltage at idle and mid rpm.
I know the 950 will boil out the battery if charging over 15 volts.

Been working on it all nite, battery after sitting all day now at 12.47 V, starter switch checked OK, disconnected wire from starter, getting 11.2 - 10.8 v at starter. doesnt seem like enough voltage, and the solenoid is only contacting intermittently, and not turning over the engine at all. Again connected the charger on start, still barely turning over or just clicking from the solenoid. I'm going to trickle charge battery overnite tonight, I'm still not sure where problem is.....battery is definately loosing voltage, and solenoid won't stay engaged to crank......not enough amps to hold solenoid and crank???Not sure how to amp test starter? I will wait til tomorrow and see how battery charge goes, but I' not too optimistic about its chancesof being good.
Fired bike and did V check and charging at 14.5 v, I am thinking that is good, and I think Joker would agree that is a good reading.
Has anybody heard of batteries loosing a cell??
I will remove starter tomorrow and see how bearings / brushes look, but this unit only has 4900k on it, my last 530 had 14,000 and was never a problem......

I would measure cranking amperage and voltage with a known good battery before I started to disassemble things. I fix this kind of thing all day long. In fact this morning first thing a machine was towed to my stall no start as the other guy could not figure it out.

If one per sues electrical problems without a proper diagnostic routine one just chases his tail literally. I once had a guy come in after he replaced his own battery, starter, and alternator with a no start. I quickly assessed the problem before it was even off the tow truck, It was just a disintegrated alternator belt a $12.00 part. He could have saved $600.00 if he would have done the basics first.

Just my opinion

The quickest solution is to take the battery out and have a load test put on it. I see that you are located in Delta. Edmonds Battery is located at 6468 King George Hwy Surrey, BC V3W 4Z3
(604) 596-8774. Take it in and they will load test it for free. If you did not have a battery tender on it through the winter it may be dead, even though it is not too old. And yes, batteries can loose a cell.

Ok, Problem Solved !!
I charged the battery overnight, it didn't take a charge, so I picked up a new one ( Yuasa ) on the way home from Cypress motorbike, they had one in stock, $39 Got home and installed and Bingo! one happy scooter again!!
I have never had a battery die while in use, so thats a first!
Thanks for all your suggestions!
