Harley-Davidson Dyna 2005 Service & Electrical Diagnostics Manual Set (P/N 99481-05)

The service volume provides mechanical repair and component replacement procedures. Electrical Diagnostics adds symptom-based troubleshooting and circuit tests for domestic and international configurations.

The referenced Predelivery and Setup Manual and Parts Catalog are separate publications and are not included.

Searchable Chapter PDFs and Wiring Detail

Text, bookmarks, and diagram labels: The content PDFs have searchable text and embedded bookmarks. The separate chapter contents files have no embedded bookmarks. Keep the extracted files together for links between chapters. Small labels in dense wiring diagrams require zooming.

The ZIP download contains 47 printable English PDFs totaling 1,078 pages. This includes the two publications listed above and a 2-page set index. Also included in that total are 32 pages of chapter/appendix contents files, including their blank backs, 14 notes pages, and 82 repeated wiring-diagram title pages.

Engine Overhaul, Chassis Service, and Circuit Diagnosis

The selected topics below show the main workshop coverage. Storage preparation and headlamp alignment are further examples from the maintenance section.

• Engine overhaul: Step-by-step engine removal and installation, top- and bottom-end overhaul, cylinder-head and valve work, and cam support plate and oil pump service.

• Chassis service: Brake bleeding, caliper and master-cylinder service, sealed wheel bearing replacement, laced-wheel truing, vehicle alignment, steering-head work, and rear suspension.

• Drive and transmission: Clutch and primary-drive repair, belt-drive service, shifter cam and fork inspection, and mainshaft, countershaft, and transmission-case procedures.

• Carburetion and EFI: Carburetor adjustment, enrichener and fuel-valve service, California evaporative-emissions equipment, EFI sensors and injectors, fuel-pump service, and fuel-pressure testing.

• Starting, charging, and instruments: Starter activation and current-draw tests, charging-system diagnosis, ignition-coil testing, speedometer self-diagnostics, and instrument and indicator-lamp faults.

• Security and wiring: TSM/TSSM setup and diagnosis, breakout-box testing, connector repair, and 41 wiring diagrams organized by fuel system and FXDWG/non-FXDWG layout.

This set is best suited to mechanically qualified owners and technicians with the shop fixtures and electrical test equipment required for component teardown and circuit diagnosis.

Engine Inspection and Overhaul Detail

Lubrication and breather descriptions accompany illustrations such as Engine Oil Flow - Top End. Piston inspection distinguishes fully coated early pistons from late pistons with oval measuring windows. Crankcase and oil-pan procedures extend the coverage into the lower end.

Component torque tables, service wear limits, lubrication and fluid data, and engine oil-pressure checks accompany the mechanical procedures.

Flywheel assembly: If the flywheel, connecting rods, or right-side bearing inner race require replacement, the manual calls for replacing the complete flywheel assembly.

Fork, Brake, and Transmission Differences

Separate front-fork sections cover FXD/FXDC/FXDL, FXDWG, and FXDX arrangements. Brake and wheel specifications accompany the inspection and repair procedures. Rear shock absorbers are replacement assemblies apart from their rubber mounting bushings.

The wheel procedures warn that operating the front brake with the wheel removed can force the caliper piston out of its bore and require caliper disassembly.

The Mainshaft/Countershaft Assembly view supports transmission inspection and assembly. Appendix D provides separate disassembly and assembly procedures for Japanese transmissions. Tapping shafts out from the opposite side, or pressing them without supporting the bearing inner races, can damage the side-door bearings.

Carbureted and EFI Fault Tracing

Carbureted models follow ICM diagnostic paths; EFI models use ECM, relay, sensor, injector, and fuel-pressure paths. The flowcharts address crank/no-start, starts-then-stalls, module power loss, misfire, data-bus faults, and individual B-, P-, and U-series DTCs.

EFI heat-management operation is also explained. This provides context for temperature-related idle reduction and interrupted injection that could otherwise be mistaken for a running fault.

Security, Connectors, and Test Equipment

Instrument sections distinguish FXDWG indicator circuits from other models. TSM/TSSM coverage includes vehicle-delivery configuration, turn-signal cancellation, bank-angle shutdown, arming and disarming, key-fob faults, security-lamp diagnosis, and password learn.

Schematics include Simplified TSM/TSSM Wiring, Starter/TSSM Circuit: FXDWG Shown, and the EFI FXDWG ignition circuit. The 12-pin Deutsch Connector (Exploded View) accompanies terminal service instructions. Amp Multilock, Deutsch, Mini-Deutsch, Packard, Mini-Packard, and ECM connector coverage includes terminal removal, crimping, inspection, and sealed-splice repair.

Test equipment is identified by part number, including Breakout Boxes HD-42682 and HD-43876, Digital Technician HD-44750, Speedometer Tester HD-41354, and Fuel Pressure Gauge HD-41182. Harness adapters and breakout-box connections support circuit testing without piercing wires. DTC tables, connector pin locations, starter/charging values, and coil and sensor tests support fault isolation.

Battery, starter, brake, and pressurized-fuel procedures carry system-specific safety warnings and require the correct isolation, support, and test equipment.

EFI Coil and Fuel-Pressure Specification Preview

For EFI models, ignition-coil specifications at room temperature are 0.3–0.5 ohms for the primary winding and 2,750–3,250 ohms for the secondary winding.

The EFI fuel-pressure test specifies a steady 55–62 psi (380–425 kPa) while engine speed is varied.
