06 Road King charging problem

Welcome to the forum from Texas. Electrical issues can be a bear and it is best to diagnose the problem in a systematic way.
There is an Electrical Subforum that has "Sticky" threads. Sticky's are permanent threads located at the top of a forum.
The electrical subforum has two Sticky's on checking the charging system. Here are the links:

2006 Touring Service manual says-
AC OUTPUT CHECK
1. See Figure 1-17. To test AC output:
2. Disconnect stator from voltage regulator.
a. Connect an AC voltmeter across any two stator connector
socket combinations.
b. Run the engine at 2000 rpm. The AC voltage output
should be greater than 30-40 volts AC.
c. Repeat AC voltage test across the other two stator
socket combinations.
3. If the output is below specifications, charging problem
could be a faulty rotor or stator. Replace the rotor or stator.
4. Check the output again as described under CURRENT
OUTPUT TEST given earlier.
Open Stator
1. Turn ignition keyswitch OFF.
2. Using ohmmeter probe, test for electrical continuity
between all three stator connector socket combinations,
that is, 1-2, 2-3, 1-3.
a. See Figure 1-16.
b. Resistance across all three stator socket combinations
should be less than 1 ohm (typically 0.1-0.3
ohms).
c. If resistance is greater than 1 ohm, then stator is
OPEN and must be replaced.
Grounded Stator
1. Turn ignition keyswitch OFF.
2. Connect ohmmeter as follows:
a. Disconnect stator from voltage regulator.
b. Insert ohmmeter probe into one of the three stator
connector sockets. See Figure 1-15.
c. Attach the other ohmmeter probe to a suitable
ground point on the engine. Check several places to
ensure good continuity is made.
3. Test for continuity between all three stator connector
sockets and the ground point with ohmmeter.
a. A GOOD stator will show a large resistance to
ground (infinite ohms) between stator socket and
ground.
b. A BAD stator will show continuity between stator
socket and ground.
4. Replace stator if grounded (BAD).
