Faulty charging system

I just installed a new battery and the bike fired right up,after riding for awhile i noticed that my turn signals quit working, caused by the battery discharging, system seems to be charging when operating at high way speeds, but at slower speeds it does not, although it seems to be charging, according to my meter,but it discharges also. my question is, is there a way to test the stator, or voltage regulator

SOURCE: I replaced my stator on my 1983 650 silver wing interstate

Where did you get the stator?? If not factory... You might want to us a volt meter and measure the resistance. You can find the resistance specs in its honda service manual. Give some more info!!

SOURCE: Harley 03 Ultra overcharging, 16 volts

14v is not overcharging. 16v is pushing it. I'm with the regulator opinion, but I would also load test your battery. If the charging system thinks your battery is low it will try to compensate by putting out max voltage, putting additional strain on the regulator, which in turn overcharges the battery... creates a vicious cycle. Is the regulator in a spot where it gets quite warm? They have a tendency to overcharge when hot. If that is the case, try relocating it or directing more airflow over it.

SOURCE: the wires going to the voltage regulator keep burning up.

Common problem with poor quality parts, the regulator is the problem, the generator is working other wise you would not have fried the wiring, you answered your own question. someone telling porkies to get more money from unsuspecting client?
The regulator controls the voltage not the generator, the generator only supplys the voltage it cannot overcharge unless the regulator is not working properly, simple!

First noticed the idle was really high last night when I started it. It returned to normal pretty quick. Battery light was on fire a minute it went off, battery is only 4 months old. Today, riding home...

sounds like the charging system is not charging when the battery is low the starter will not disengage properly disconnect battery and charge it while battery is out with bike in a high gear 4th 5th push bike back and forth this should unengage starter once your battery is charged and back in bike if the starter engages and dis engages properly then you will need to test your stator output with a multi meter look on you tube for video to test stator good luck

What to do when motorcycle will not start tipped over tries to start but wont fire up

How old is the battery? You need to check if the alternator is putting out a charge, is the regulator working. A dead cell in the battery will often show a full charge state if you try to charge it. When you try to start the bike the battery is required to give a high charge to the starter. The buzzing you hear is probably the starter solenoid trying to work. I would suggest fit a new battery and if the bike starts OK check out the charging system. 14.4 volts is the normal reading across the battery with the engine running at 5K.

What is the problem? A 2003 FXDX-T with a 2 year old OEM H-D Battery. What should the Volts be on a "fully charged" Battery. I have a reading of 12.4 Volts. At "high idle" the reading is 14.26-27 Volt

With a reading of 14.2 volts at high rev I believe your stator is right on the money.I would say that a new battery is in order.Take the old one out ,charge it overnight,and have them perform a "load test" to confirm before you buy a new one. good luck

I bought a new battery, the bike road fine for a while the in the middle of my ride it started slowing down to a complete stop. I couldn't start it again, waited for 20mins, started it and it ran...

One explanation for this would be that your charging system is faulty. It is possible that the OLD battery was ok, but was not getting charged by the faulty charge system. You put in a new battery, that is part charged before sale and ran the battery flat because it wasn't charging. If you leave a discharged lead acid bettery for 20 minutes or so, it will pick up a little again and possibly let the bike start and run, but by the time you got home you had killed the battery completely.

All the facts fit, though I'm not promising that it is the problem.

Take the battery off and charge it with a charger. Now, put it back on the bike and run the bike (It should start) While the battery is on the bike, get a volt meter on it. It should read slightly over voltage (doesn't matter if its a 12 or 6 volt system, it will read a little over when the bike is running) when you turn the engine off, you should see the volt meter drop down to the stated battery voltage. If you get no hike with the engine running and drop as you power off, its a good sign the charging system is faulty. A similar test, start the bike, meter the battery and turn on the indicators, stop light and head light to pull as much power as you can, the battery voltage shouldn't dip, because the charge system should compensate. If it does dip, consider this a confirmation that the charging system is faulty.

1982 500cc honda silverwing, bike is charging @ aprox. 11.5v , also when right signal is put on right side running lights go out, are the 2 conected(ground short) ? or maybe stater? , new to bikes with no...

1st, Your alternator is charging real heavy. the lower yhe voltage the hidher the amps. 2nd, yes, Turn on one and the other dima is indicarive of a poor ground which would in turn affect the charging rate. Nowm The bad ground is more than likely the battery cable on the negative. But, Check the other end of the cable also. good luck- Ned

Bad battery

Don't rely on on whether the bike will start at a gas station to determine if the charging system is working. Get the multimeter out and do a proper test. Should be getting about 14.5 volts @ around 3K RPM. It's too easy of a test to to just skip. If it is charging then start looking for something else. Was the new battery properly charged to begin with? Loose battery connection? I suppose the GPS could be too much but you said that it was dying last november, so I would suspect something else. P.S. you need a properly charged battery to get an accurate reading for the charging test.

Battery ques

Put a voltmeter on the battery. Everything off the battery should be 12.6-12.7 volts or so. A little higher or lower is o.k. Start the bike. Rev up to about 3000 RPM. Voltage should climb and then go to about 14.0-14.5 volts or so. Again a little over or under is O.K. If the voltage doesn't climb above 13 volts or goes over 15 Volt you definitely have charging issues.,,,
