Ive put a multi meter on the battery when its running the tester says 12 volts so i know its not charging what can i look for and how do i fix it please
Most bike have an alternator driven off the left-hand crankshaft shaft.
This turns with the engine, producing the AC charging power.
This power then runs through a voltage regulator, that both converts the the AC voltage into DC voltage, and regulates the amount of voltage flowing into the remaining electrical system.
Now, you did do the first step correctly.
DC volt meter to battery terminals to see if you get 13-14 volts DC with engine running.
Next, locate voltage regulator and unplug connector for wires coming FROM the regulator, and hook up the DC voltmeter.
With engine running, you should have 13-14 (or so) DC volts.
If not, locate and unplug wires coming from alternator to regulator, and hook up AC (note change from DC to AC) voltmeter.
With engine running, should have AC voltage (this could be 20-40 volts or more).
This will let you know where the problem is, and what needs to be replaced.

Probably yes.But to be sure for your measurements put the battery on a charger for 12 hours to be fully charged.When you take it out of the charger it should be reading 12,5V even after 20 hours you have take it off the charger.Then put it on the bike again and measure the current on it's poles in 3-4000 rpm with your high beams on.It should be reading 13,5-14,5V.If not then renew the regulator/rectifier.

Hi and welcome to FixYa,
Initially, have you checked the 30 Amps main fuse and its holder clips? It would be integrated with the starter relay. The fuse or the fuse holder may have heat related problem(s) causing it to loose conductivity when hot.The fuse may require replacement even if it tests good and/or the fuse holder would need cleaning / crimping. To locate the starter relay (main fuse), follow the battery cable from the + terminal of the battery.
Please postback results.
Good luck and thank you for asking FixYa.

i know this sounds silly ,but when you bought the battery had it been activated,new batterys are critical in their first charge and you cannot use a standare type automotve charger,if bought dry the battery needs to have the acid filled ,left to sit for at least 2 hours prior to charging,once it has sat for the 2 hrs with the acid in,the new battery will need to be charged with a "cteck"or similar type charger for at least 13 hrs before it can be put into normal service,what happened with yours i think is that sure you gave it a charge but it has only recieved a "surface charge"and will be usable for a very short time,it may recover for a brief period and go again untill the surface charge dissipates,(or in other words ..runs out of charge)best thing you can do with the battery is take it to a auto electrician and have the battery cycled and conditioned,this is not expensive to do and will give you piece of mind,after conditioning the battery shouldngive excellent service,i have the battery in my goldwing coditioned about every 12 months and i have the same battery that was in the bike when i bought the bike 8 years ago and still no electrical or battery problems(costs about $25 to get it done)once a year but that beats $280 for a new one...hope this helps

I had the same problem with my 900 that I just bought, the regulator was fried, so the local kaw shop replaced it with a new one off internet, then it promptly fried the new one, upon further investigation the rotor/armature was reading 1 ohm resistance, supposed toread 4/7 i think anyway, had to have alternater rebuilt , cost 370.00 , works fine now.

voltage reg. may be bad.19 Volt DC will destroy other electrical, dont run it and risk it.
