Troubleshooting:
Occasionally, the stock American Iron Horse ignition switch can “chatter” due to vibrations at high engine RPM. This can
cause the gauge to operate incorrectly. It is recommended to solve this problem by replacing the stock ignition switch with a Harley
Davidson switch (HD kit number 71441-94). This switch is less prone to chatter.
