Charging problem 2000 roadking - 2000 Harley Davidson FLHR-FLHRI Road king

First, your battery MUST be fully charged to perform these test. You'll need a good DVOM (digital volt ohm meter) but an analog meter will work. Connect the meter across the battery with the read lead to the positive post and the black meter lead to the negative post. Put the meter's function switch in DC VOLTS, 20 VOLT range. Start the engine and bring it to a high idle. Your meter should show a slow build up of voltage over about a thirty second period of time. It should read 14.5-15.0 volts.

If not, you'll need to test the alternator. Unplug the regulator at the front of the engine. Look inside the connector in the engine case and you'll see two metal connectors. Put one meter lead into each contact. It makes no difference which lead goes to what connector because we're checking AC voltage. Now, set your meter function switch to AC VOLTS, 50 VOLT RANGE. Start the engine and bring it to high idle. You should read at least 30 volts.

If you read 30 volts or more at the alternator but less than 14 volts at the battery, replace the regulator. Naturally, less than 30 volts at the alternator, replace the stator

Good Luck
