For some reason, my DWG is not holding its charge. I recently purchase and change a new battery. I could ride approximately 2 hrs and then the battery goes dead. Any help or suggestions would be appreciated.

 

sounds like you are running off the battery, you need to get a volt meter and start
checking things... first charge battery ( still possible new one is bad ) then check battery voltage with bike not running.. then start the bike and check the voltage static and then rev the engine a few times to about 2k..


see if voltage rises and just how high if it doesn't then you need to get a repair manual and start checking the electrical system.. the system is beyond MOST backyard mechanics ability to repair other than a voltage regulator swap out

 

Here is a link to the electrical section. There several "stickys" at the top that can help you through the diagnosis.

Voltage regulator problem most likely.

 

Could be -> battery..., regulator..., stator... wiring in between

Isolate - troubleshoot..., identify..., replace defective part(s) - or clean the connections

Need a VOM

My son had exactly the same problem; however, the most he got was 30 minutes before bike died completely. Turned out to be a bad stator.

 

On my EVO, the charging system lasts about 50-60,000 miles. Replaced it 4 times on my Dyna.
