well its not useless but its not working properly,
im 99% sure its not charging properly
the battery goes flat very quickly from using the electric start
when we tested the battery with a multimeter it stayed at the same voltage even when the engine was revved :bash:
does any one have any ideas on this or had any similar problems??
any help would be greatly appreciated
the bike is a 350 kitted Ktm 250 exc 2005
the battery is a kiwi x battery

Just check if the battery connections are clean, not just firm. And make sure all connections, are properly connected. Follow the cable back and check all the joiners.

Get your starter motor cheeked out at a auto electrition. Could be drawing excess current. Worn Brushes or Burnt winding..........

start it, take one of the cables off the battery, measure voltage on + and - cables. if its 0v or similar, then your charge system isnt working, if its 12ish, its not working properly, if its 13 or higher its all good and your battery is poked

erm, you are describing how a regulator works. it prevents the charging system overcharging. But you give no figures.
I would expect it to stop at anywhere between 13.7 - 14.5V. Is it in this range? What does the battery voltage sag to when sitting overnight? What about when you use the starter?
Could easily be a shagged battery, the rough environment & infrequent use kills them. Doesn't sound like a reputable name. A japanese Yuasa or GS would be a better long term affair. Trickle charge off the bike when not used for a while.

some ktms came out lecky start / kickstart but no charging coil in them its up to you to charge battery before you ride mate had a exc400 like that was great for 1st half of the day ( battery was a bit shagged) second half of the day was all kickstart real dumb idea.

i quite sure it does charge because there didnt use to be a problem
the voltage on the battery when running is 12v and this doesnt change regardless of revvingness

with it idling with the light on, the light is quite dull, but increases brightness as the bike is revved

Ok, Exactly how does an expensive battery make the bike charge ?

Then obviously it has a charging coil aye?

Sounds like the voltage regulator/cutoff is faulty.Have you tested it with the engine running and the light on? Does it drop or stay at 12 or what?

it's a piece of shit that you'll never get fixed properly.................i'll give ya $50 for it
pm me me to confirm sale

Well you still didn’t answer all the questions, not super keen on an answer? or just think that they aren’t important? Would have been interesting to know what the battery was reading in other states.
But what you have said is 12V even when revved. That sounds awful queer. 12V is flat. Either the regulator is regulating at a crazy voltage (don’t believe unless someone stupid has made one). Or the battery isn’t connected to the charging system.
Maybe Barty5’s coment which seemed like KTM were crazy was actually on the money. Try trawling the KTM websites like DRN.net they have a KTM category.
If they really were relying on you charging the battery every time then it’s new battery time (probably is anyway). As batteries dies they either increase in internal resistance & they can’t supply the current required or vibration kills the plates with much the same effect.

What i did point out was that mates bike being a EXC did have lights and ran enough through its system to run the lights. This of coruse can lead you to think there is a charging system as they did at 1st. I would be in touch with a dealer with chassis number and model have have them check save a lot of time and hassle looking for a fault that may not be a fault. (Other than a dumb KTM design fault)

I wasn't trying to dismiss you, it just sounded so far fetched, like the total afterthought. Not what you would expect from a factory at all.

ohh man does that mean it doesnt come with the super luxury exhaust and front and rear shockers:weep:
ok we took it for a ride on sat, and the starter worked perfectly all day, which is different to the week before when it would just turn over once or twice then go dead after just starting the bike in the first place
the only thing we did differently this weekend was charge the battery the night before instead of a few days before
if the battery was dead what would it read on a multimeter?
both batteries read 12v in the bike and this does NOT change at all with or wothout revving
the light gets brighter when the bike is revved though, so i think its fair to say that it does have some way of producing power even if this seems to be a new recent concept to the austrians:Pokey::mad:

Well open voltage on a battery is a poor test, but should be 12.7 if it is fit, maybe sagging to say 12.4 after being left a day after charging for a small battery. But really it isn't as clear cut as that. If it is down to 12V that sounds pretty spent & obviously isn't holding a charge very long.
(if it was charging will run up to 14ish volts when revved a bit off idle).

:Oops:was i meant to be specific it is about 12.7V then, but it definately doesnt change when its revved from idle
no, thats chinese!
oh yea sorry, thats right so ill be importing the super luxury exhaust and shockers from china then, so i spose KTMs are rice eaters cuz they dont like japan than??:whocares:

too late: i traded the 950 for a Duke and a pile of cash
now we've only got a Ducati, a Buell, a BMW and two KTM's left: I feel so naked!
