Question about BMW K 100 RT Motorcycles

Flickering lights, bike not starting

Ok. So, I have been using a battery regulator the past few weeks and hadn't had any issues with it. Although my battery is only a month old, I was told that I should use this to maintain it...Anyway, I unplugged this the other day and left for work. On the way there, my tach/speedo lights and headlights/turn signals began to flicker. On my way home, the lights did the same thing and eventually went out completely. I turned off the bike for a few minutes and when I went to start it, all I got was a buzz...I let it sit for 20 minutes or so and it fired up. Today it started up, and I rode a mile, turned it off for a few minutes, went to start it and buzzz...Let it sit for about an hour, and tried again...buzz...Since I was relatively close to my house, I had a buddy push me a bit and I was going to push/coast home. After moving fifty yards, I turned the key and 'boom', it started... I removed the battery, cleaned the contacts, had it tested...All are fine.... What do I do???

SOURCE: My 2002 TW200 won't start,

Hi, seems to be eletrical issue. Make sure if the battery works properly- check voltage. Weak battery can have correct voltage level when it is retiring, but when you e.g. push the starter, it quickly looses power.

If the battery is OK, it could also be a short circuit somewhere. You mentioned the carburetor cleaning- check if the heater unit cables on the carburetor are plugged correctly. Also, check fuse.

Why won't my lights work


It sounds like your alternator is not charging the battery. Fit a new battery remember to undo negative lead first to remove and fit positive lead first to refit the battery. When the new battery is filled please charge it using less than 1 Amp DO NOT use a car charger or try to jump start it. Your new battery should show 12.5 to 13 volts on a meter for a 12 volt system and 6.3 to near 7 volts for a 6 volt system. Start the scooter and check across the battery terminals your meter should show about 14.4 V for 12 volt battery and about 7.5 V for a 6 Volt one. No voltage increase means your charging circuit is not working. Either the alternator or rectifier(regulator) are not operating correctly. Worst case scenario is both units dead.

Hi there. I have a Yamaha YBR 125 on an 07 plate. It's the fuel injected model. Its developed a serious and dangerous fault that I just can't seem to find an answer to on the Internet... When...


Hi, Shine_on_you and the usual suspects are:
1. Severely discharged or a damaged battery should have 12.5 volts or better and be able to pass a proper "LOAD" test if necessary your battery may show 12.5 volts or more but have little or zero amps and must be replaced.
2. Failed alternator/generator and or voltage regulator.
3. Loose or corroded battery terminals and or cables especially the "NEGATIVE" cable, look for loose, corroded, or broken connectors inside the cable harness at "BOTH" ends.
4. Failed main circuit breaker or ignition switch, check for loose connections and continuity.
5. Failed system and or ignition relay, check for continuity.
6. Failed ignition coil, ignition/electronic module.
7. Failed CKP, CPS, CMP, MAP, TPS, or BAS sensor, corroded, loose or broken wire connector pins/sockets.
8. Throttle cables and or idle speed improperly adjusted hot idle speed should be 950 RPM to 1000 RPM.
9. Fuel tank empty.
10. Fuel tank contaminated with ethanol sludge.
11. Water or dirt in the fuel system, or clogged filter.
12. Restricted, blocked or kinked fuel line.
13. Faulty fuel pump.
14. Faulty pressure regulator.
15. Faulty or clogged fuel injectors.

Can't start my Honda CB400-Four 1997. Battery seems to be ok. Could it be the Regulator/Rectifier? It has been lying up over the winter. It did start a couple of weeks ago, cut out and hasn't


if the headlight dies right out when you crank the motor then the battery is usually dead. It may read on a voltmeter that it has 12 volts but that does not necessarily mean the battery is charged.Have the battery checked and charged properly then try and start the bike again.Regards

I have a 2003 Deuce and my OEM battery went bad, when I would start it the check engine light would come on and then go off after about 30 seconds. Then it left me stranded, while driveing the bike went...


G'day.
Sound very much like a low charge rate(your bike is not recharging the battery).
You need to have the bikes charge rate checked.
Basically-your bike should charge at a rate of 13.4- 14.2volts(DC) when running.
If it's not- the battery will keep going flat.
The test is performed by starting the bike & placing a voltmeter across the battery to measure the output.
It's a relativily quick & easy test to perform that only takes a few seconds-but if the charge rate is low then its caused usually by the regulator or the alternator(stator).
If you have a multimeter-or know someone who does-then the test is pritty easy & you need to do that before you go any further.
If you do it yourself- set the meter to Volts DC at a range higher than 15volts(if the meter is not auto-ranging) run the bike with the volt meter probes touching the Battery(black probe to battery negative-red test probe to battery posative) & observe the voltage reading.
You want 13.5 to 14.2v.
If you can't do it yourself then an auto-electrician or bike shop should be able to do it while you wait for just a few dollars.(only the test though- if the charge rate is low then you have then other issues to solve)

I hope this was of some help
Kind regards Andrew Porrelli

2003 Ultra Classic fuel injected model. Generally runs well, but at times (seems when it's been run hard for an hour at least) I see the volts go way up around 16 or 17; it normally reads 14.5 volts Soon...


Your Voltage should never get that high. Anything over 15volts is bad news. Try Testing your Regulator. First do a Bleed Test.
REGULATOR BLEED TEST
Be sure regulator is connected to battery. Unplug the stator connector.
Use a trouble light and clip it to a good ground and the other to the regulator pins, one at a
time. If light comes on regulator is bad.
