Electrical System Diagnostics

This section breaks down critical starting and charging procedures. You get the exact starter motor troubleshooting steps, alongside solenoid pull-in and hold-in tests. It covers free-running current draw assessments to pinpoint electrical issues early. For the charging side, the manual documents rotor and stator inspection techniques, AC output checks, and voltage regulator testing. It also lists specific job/time code values for warranty claims. Expect clear diagnostic notes for correctly testing circuits using a breakout box. Working on motorcycle electrical systems carries inherent risks regarding high amperage and potential sparks; always follow standard shop safety practices and verify power isolation before probing any circuits.

Instrument and Security Module Coverage

Modern Harley electronics require precise data. This chapter maps out the turn signal module and the Hands-Free Security Module (HFSM). It details how to access and read speedometer self-diagnostic modes without guesswork. You will find comprehensive tables listing DTC priorities, wiring connector terminal functions, and acceptable milliampere draw limits to track down parasitic drains. Note that this page provides a contents overview for the reference material and does not replace the step-by-step diagnostic instructions found inside the publication itself.
