CHAPTER 1 INTRODUCTION
1.1 General Information
38 AMP 3-phase charging offers more current delivery over traditional 2phase systems to feed power-hungry accessories like today’s sophisticated
EFI systems and other electrical accessories. Using a highly-efficient “series”
regulator, the ASM2005 fits all EVO-style motors.
1.2 Special Tools Required
Most of the installation of the 3-Phase Charging System can be completed
with basic hand tools. However, a few special tools make the job much
easier:
• in-lb torque wrench
• 5/32” Allen driver
• Contact cleaner, alcohol, or glass cleaner
• General-purpose wire stripper and terminal crimper
• Heat gun
• Multi-meter or Test Light
CHAPTER 2 SYSTEM INSTALLATION
2.1 Factory Stator and Rotor Removal
1. Disconnect the negative battery cable
2. Using your motorcycle’s specific repair manual instructions, remove the
primary cover, primary drive, and clutch.

3. Using your motorcycle’s specific repair manual instructions, remove the
rotor and stator.
2.2 3-Phase Stator and Rotor Installation
1. Insert the wires and grommet through the hole in the case. Support the
stator during this step.
Figure 1—Routing wires through grommet hole
Tip: You may find it convenient to rest the stator on the sprocket shaft while you
route the wires and install the grommet through the case hole.
WARNING! DO NOT ALLOW THE STATOR TO HANG FROM THE OUTPUT WIRES.
DOING SO MAY RESULT IN DAMAGE TO THE WIRES AND/OR STATOR.
Tip: Use castor oil applied to the rubber grommet to provide lubrication when
installing the grommet in the case. Castor oil is available from any pharmacy,
and works the best of any lubricant we have tried.
WARNING! DO NOT USE THE WIRES TO PULL THE GROMMET THROUGH THE
CASE HOLE. DOING SO MAY RESULT IN DAMAGE TO THE WIRES, OR
THE WIRES SLIDING THROUGH THE GROMMET.
2. PUSH the grommet through the hole until the first barb is exposed on the
outside of the case.

Figure 2—Grommet installed in case; first barb
exposed on outside
3. Insert the terminals into the connector housing (supplied) until you hear a
“click.” The specific location of the wires in the connector housing does
not matter.
Figure 3—Install stator terminals into connector
housing
4. Locate the stator on the case and align the bolt holes. Fasten in place
with the (supplied) 10-24 X 1.00” socket head cap screws. Tighten to 5575 in-lbs (6.2-8.5 Nm).

Figure 3—Install stator bolts and tighten to 55-75
in-lbs (6.2-8.5 Nm).
5. If equipped, install the grommet retaining set screw. Do not over-
tighten!
WARNING A GROMMET SET SCREW THAT IS TOO LONG OR OVER-TIGHTENED
MAY PIERCE THROUGH THE GROMMET AND WIRES, SHORTING THE
STATOR TO GROUND.
6. Test the stator leads for shorts to ground. See “Troubleshooting,
Stator Failure Test: Shorted to Ground.”
7. Install the rotor spacer on the sprocket shaft (supplied).
Figure 4—Install rotor spacer over sprocket shaft
8. Install the rotor on the sprocket shaft. Make sure the rotor is fully seated
against the rotor spacer on the sprocket shaft.

Figure 5—Install rotor onto sprocket shaft and
seat against rotor spacer
9. Install the compensator extension shaft on the sprocket shaft
10. Using your motorcycle’s specific repair manual instructions, check for
proper chain alignment. Use OEM-specified shims to bring chain
alignment into specification if required.
11. Using your motorcycle’s specific repair manual instructions, install the
primary drive and clutch. Assure that all driveline components line up
correctly.
12. Apply Loctite Threadlocker #262 (“red”) to the threads of the sprocket nut
(also supplied with compensator shaft extension kit). Tighten sprocket
nut to 150-165 ft-lbs (203.4-223.7 Nm).
13. Using your motorcycle’s specific repair manual instructions, install the
primary cover.
14. Connect the negative battery cable.
2.3 Factory Regulator Removal
1. Disconnect the negative battery cable.
2. Using your motorcycle’s specific repair manual instructions, remove the
regulator. Save the factory-supplied hardware.
2.4 3-Phase Regulator Installation
1. Connect the 3-pin stator connector to the regulator.
2. Using the factory-supplied hardware, locate the 3-phase regulator on the
mounting bracket and install using the factory-supplied hardware.
Tighten to 50-80 in-lbs.

3. Attach the ground wire between the bracket mounting bolt and the
bracket. Tighten to 70-100 in-lbs.
4. Trial-fit the long power wire to the motorcycle, and route to the original
location of the factory regulator wire on the circuit breaker.
5. Trim any excess wire, and strip 5/16” of insulation from the end of the
wire using a wire stripper.
6. Slip the 1” length of heat shrink (supplied) onto the wire.
7. Crimp on the (supplied) ring lug to the end of the wire, taking care that a
good crimp connection is made.
Note: A poor crimp connection may not allow your 3-phase charging system to
function properly.
Figure 6—Suitable crimp connection
8. Slide the heat shrink tubing over the crimp to insulate the connection.
Use a heat gun to shrink the heat shrink tubing.
9. Attach the regulator power wire to the circuit breaker.
10. Use nylon cable ties or other appropriate means of securing all wires to
prevent damage from vibration.
11. Enjoy your newfound charging power!
APPENDIX A TROUBLESHOOTING
A.1 Testing Overall Charging System Performance
1. With the engine running, use a multi-meter to measure the voltage
across the battery terminals. Under maximum load (fully drained
battery, lights on, etc.), voltage should be between 14.3 to 14.7 volts
DC.
A.2 Testing Stator Output
6 EI2005.doc
Page 11
Thunder Heart Performance Corp. 615-672-8811 www.thunder-heart.com
1. Disconnect the stator from the regulator
2. Bring engine speed up to 1,000 RPM.
3. Use a multi-meter to measure the AC voltage between any and all
combinations of the stator output terminals. Output should be around
16v AC at 1,000 RPM, and increase with engine speed (Figures 2
and 3).
Figure 7—Measure the AC voltage between each
stator output terminal.
Figure 8—Voltage between any terminal
combination should be around 16v AC at 1,000
RPM.
A.3 Stator Failure Test: Shorted to Ground
1. Disconnect the stator from the regulator.
2. Use a multi-meter to test for continuity between any of the stator outputs
to ground. There should NOT be continuity between any of the stator
outputs to ground (Figures 10-12).
