Electrical problem with f gs 650

Check the battery and replace with a new one. If the battery is good, the harness from the ignition switch to the frame could be broken.

If your Charging system isn't working properly it won't. Take a Multi Meter. Take the Leads to your battery. Start the Bike and run it up to 2k or higher rpm. The Voltage should increase the higher your rpms get. Up to 14vdc or about. If it doesn't go up then something in your charging system is acting up. Stator, Regulator something of that nature

The rectifier that is within the charging/electrical system sounds like it is gone.It may not be , but from what you posted,it seems like it.Hope this helps

sounds like your battery is dead. You may have enough volts to turn on lights, but not enough amps to turn the starter motor. put a volt meter on the battery and see how far the volts drop when you try to start. my guess is too low. Replace the battery, or have it tested; it probably wont take a charge.

hi,this might help,if you have a digital volt meter,take a reading across the battery at rest(key off)should be about 12.8-13.2v.start the bike and take a reding across the battery if the bike is charging properly the meter should read between 13.8-14.2-14.4v.to check if the regulater is working correctly,connect the meter across the battery and slowly lift the rpm from idle up to about 3-3500rpm,the reading on the meter shouldnt vary much more than 1-1.5v across the rev range,if the reading fluctuates up and down with the rpm(more than about 1-1.5v)then the regulater is faulty,and obviously if the battery is showing no difference from rest to high rpm then the stator is probably at fault..hope this helps..cheers

It's one of these things: The battery. Especially if you're still using the original one, which is now almost 10 years old. The charging system. Or the starter relay.
Even if your battery isn't 10 years old, if it has sat for more than a month or so without being charged, then it is toast. A fully charged 12 volt battery should show about 13.5 volts on a volt meter.
If the battery is good, then you will need to find out if the charging system is working. To do this, you will need an ampere meter capable of reading up to 10 amps. Start the engine and THEN hook the amp meter in series between the battery (either side) and the cable going to the battery. With the engine revved up to around 4,000 RPM, the charging system should be putting out at least 5~6 amps.
If it isn't the charging system or the battery, check for a bad starter relay (the thing that makes that buzzing sound when you hit the starter button). Perform this test by bridging across the two large cable connections on the top of the relay with a large screwdriver. If the starter spins when you do this, then you've got a faulty starter relay. If the starter doesn't spin, then you've got a bad starter motor or a bad electrical connection going to it.

you have a charger thats kicking out 45 amps,,,just how much more do you need? i know the lady sayes she's cold, but realy???? why not strap a 2500watt jenny to it and she could have a kettel to make hot drinks on it as well as run the heated blanket and the **** warmer???? if you could put a bigger charger on it the motor could not turn it over, trust me,,, the only real way is ,,,dont ride it if its cold! or get some realy thick wooly knickers,, after all look at it this way,,,
have you ever seen sheep shivering??????
and there is nothing heated on them????

Battery condition? Make sure battery connections are clean and tight this is a very common problem.
