2008 harley dyna high voltage

depends on the state of the battery , The regulator looks at the battery charged state and regulates the voltage to fully charge it , If the voltage does not drop back after a few hours the battery could be on the way out.

I changed my stator out on a 2003 fxdx dyna glide and it still wont keep my battery charged , i also put a new regulator and battery on it . help

Well, that's all there is to the charging system, a stator, a rotor, a regulator, and a battery.

Charge your battery until it fully charged. Take a digital volt ohm meter and connect the red lead to the positive and the black lead to the negative lead of the battery. Put the meter in DC volts, 20 or higher range. Start the engine and bring it to a high idle. You should read 14.5 to 14.8 volts on the meter. If so, your charging is working as it should. If not, proceed to the next step.

With the engine off, find the plug where the regulator plugs into the engine case. Unplug the connector and look into the part that is inside the case. Using your DVOM, put one lead into each plug or pin in the connector. Be careful not to touch the sides of the case and it makes no difference which lead goes to which pin as the voltage is Alternating Current instead of Direct current. Put your meter in AC voltage, 50 volt or higher range. Start the engine and bring it to a high idle. You should read 30 volts or higher. If not, something is wrong with the stator. As long as you have 30 volts or better, your alternator is working as it should

Your regulator must have a good ground. I always put a 'star washer" on the regulator mounting bolts between the regulator and the frame.

If you used a new rotor, I have run across one rotor during my time that the magnets were not strong enough. You could hold a screwdriver up to it and tell right off that it wasn't right. Only seen it that one time though.

Good Luck

D08 code on 2002 dyna

D08 means over-voltage. Your bike is over charging and will cook your battery. You regulator will have to be checked as well as your stator. If you have to drive to a dealership, keep your revs down as low as possible, at least not above 2000 revs. Do not drive more than a few miles or battery may get damaged. The letters simply mean set. So you have D08SEt which means D08 set.

I think I have a bad stator on my 2002Harley Dyna

too many variables !
Firstly check battery under load ! any battery place or auto electrician can so it usually free!
do this before replacing any thing else!
make sure all connections are clean & tight
if battery is ok get them to check the charge rate on bike! its a simple test or you can do it with a volt meter they are only cheap to buy!
