antonio carroccio Posted October 11, 2004 Share Posted October 11, 2004 Since a couple of weeks the lamp of the battery goes on in the dashboard. I did take a look in the little generator besides the claxon and the oil dispenser and every wire is fixed at the right way. The wires by the battery are also good. I don’t understand. Can some of you light me up??? Link to comment Share on other sites More sharing options...
GuzzTim Posted October 11, 2004 Share Posted October 11, 2004 Antonio Is the battery strong enough to start the bike ? Does the light come on while driving ?? At all RPMS or only when idling ? Take off the seat, start the bike, and check the voltage across the battery. It should be greater than 13.5V. Ciao Link to comment Share on other sites More sharing options...
antonio carroccio Posted October 11, 2004 Author Share Posted October 11, 2004 Hi GuzzTim, I just have reads your topic. You also have had problems with your battery. My bike does start well and all the things in/up/on the bike are doing very well. Only that stupid red light goes on. Is this the begin of the end??? How did you solve your problem???

GuzzTim Posted October 11, 2004 Share Posted October 11, 2004 Antonio.. I solved my issue by my dealer giving me a new battery under warranty !!! Great dealer.! With your problem, either the light is coming on wrong (there's a short in the light) or the light is working correctly and the charging circuit is not working. If your bike is not charging the battery, and you've been riding like this for awhile with lots of starting, I would expect your battery to be dead... If the bike is not charging then at some point the battery will simply drain itself to zero.. I think the best thing would be to check the voltage at the battery (do you have a voltmeter or multimeter ?).. If its charging, then you may have a simple short that causes the light to stay on.. Is the battery light on ALL the time while you ride ? Ciao, Tim Link to comment Share on other sites More sharing options...
callison Posted October 12, 2004 Share Posted October 12, 2004 Get yourself a good voltmeter that reads AC and DC. Make sure the battery is charged. Before starting the bike, detach the alternator wires, they're two heavy gauge yellow ones. They're probably somewhere up under the front of the tank or in the frame around the coils someplace. Put your meter on the 100 volt AC scale, hook it up to the two wires from the alternator, start the bike and watch the meter as you rev the engine up. At 7000 rpm, there should be about 90 Volts AC on those two wires. If you read a good sized AC voltage as you rev up the engine, you most likely have a dead voltage regulator.

antonio carroccio Posted October 28, 2004 Author Share Posted October 28, 2004 Somebody else who knows where can I get a new battery? In Holland, Germany, Europe? Somebody knows some site to looking at? I start thinking my battery is dieing. Thanx all Link to comment Share on other sites More sharing options...
twhitaker Posted October 28, 2004 Share Posted October 28, 2004 If your light is coming on only at idle, you might try raising the idle speed a little bit. Should be around 1100 RPM. My light comes on if I let it idle below 1000 RPM. Link to comment Share on other sites More sharing options...
Gio Posted October 28, 2004 Share Posted October 28, 2004 Antonio, Not so fast on the new battery (although this could be your problem) - I too have experienced the battery light coming on for a few seconds at a time (usually at around 2 or 3000 rpm but also when first starting if idle is low) for several weeks but my battery still seems to be charging ok so I have not worried about it too much.

helicopterjim R.I.P. Posted October 28, 2004 Share Posted October 28, 2004 Take off the seat, start the bike, and check the voltage across the battery. It should be greater than 13.5V. This is the key test! If your bike is not charging then you will need a large number of new batteries to keep your bike going. If it is charging and your bike starts OK then you may only have an indication problem and still do not need a new battery. Until you check the voltage when the bike is running you cannot proceed to the next part of troubleshooting. Link to comment Share on other sites More sharing options...
antonio carroccio Posted October 29, 2004 Author Share Posted October 29, 2004 Sad but true, my battery has died this morning. Yesterday it was alive but this morning the tragedy….dead! Well I was at some battery gooroo yesterday and we measure the battery. It was indeed less than 13.5 V. It was around 12 – 12.3 V. This guy said to me maybe the main problem is the dynamo. But it could be also the end of the battery. Well, my next step, I’ll buy a new battery and a battery charger. I have spoken with somebody who has battery with gel. I've heard around that this kind of battery is the best. We’ll see. Damn….I am walking again. MERDA! Thanks you all. Link to comment Share on other sites More sharing options...
helicopterjim R.I.P. Posted October 29, 2004 Share Posted October 29, 2004 Antonio. In order to determine if your dynamo is not functioning properly the voltage must be measured with the battery installed and the engine running. It sounds as if this is true so perhaps your battery is OK. I reccomend that you confirm that your dynamo is not OK before buying a new battery.

GuzzTim Posted October 29, 2004 Share Posted October 29, 2004 Antonio To test the battery, its not enough to just measure the voltage. My dealer connected the battery to a deep charger (ie. 6 amps or greater) fully charged it, and then did a load test. It passed the test ok, but was dead two days later. Second, it is really easy to test the charging system on your bike, per my original post, or what Helicopter Jim says in the above post. Third, I thought gel batteries were what came stock in the V11. Regardless, my dealer replaced my battery with a new Wesco gel battery. Apparently you don't need a charger with the new gel batteries, although I have a BMW gel trickle charger that I bought for my old one... just in case.

jrt Posted October 29, 2004 Share Posted October 29, 2004 Tim, The newer gel batteries require a higher overvoltage to charge. I'm not sure the older tricklechargers work so well on the gel-style battery. But I'm not sure- won't hurt it I suppose. I've been thinking it's about time for my original battery to go south too. Probably by spring, but so far, so good (almost 4 years) j Link to comment Share on other sites More sharing options...
Admin Jaap Posted October 29, 2004 Share Posted October 29, 2004 The original batteries are gel-type, aren't they? I thought these were the only ones that didn't need to be mounted upright. Link to comment Share on other sites More sharing options...
badmotogoozer Posted October 29, 2004 Share Posted October 29, 2004 The original batteries are gel-type, aren't they? I thought these were the only ones that didn't need to be mounted upright. 36314[/snapback] Stock battery is a gell cell. As Jaap says, these are the only ones that can be mounted sideways, and you must replace with same. Rj Link to comment Share on other sites More sharing options...
