GENERAL
Kit Number
66000005
Models
This Three-Pin Battery Charging Harness fits all Harley-Davidson® motorcycles equipped with a 12 volt battery, and allows an easy connection to any Harley-Davidson battery charger equipped with a black quick disconnect connector to properly charge and maintain the battery. The LED indicator light will flash red when the battery needs charging. Regularly monitor the status of the indicator light. If battery voltage falls below 3V, the indicator light may no longer flash.
Additional Parts
NOTICE
Always use replacement fuses that are of the correct type and amperage rating. Use of incorrect fuses can result in damage to electrical systems. (00222a)
NOTE
A replacement 7.5 A Type ATO automotive fuse can be purchased locally.
OPERATION
- If the battery charge is low, the low battery charge indicator light on the harness will turn on after being connected for 60 seconds.
- Connecting the harness to a Harley-Davidson® charger will turn off the low battery indicator light.
- If the motorcycle's ignition switch is turned on and the vehicle is not started within 60 seconds, the electrical draw from the headlight or radio may also activate the indicator light. The indicator light will turn off when the motorcycle is started.
INSTALLATION
NOTE
Several variations of battery terminals and connecting hardware have been used over the years on Harley-Davidson motorcycles. Refer to Figure 1 to determine the terminal and hardware type used on your battery.
The indicator light may initially flash upon installation. This is normal. If the light continues to flash after installation is complete, connect your battery to a Harley-Davidson approved charger.
The following procedures apply to all models when connecting and disconnecting battery terminals.
WARNINGTo prevent accidental vehicle start-up, which could cause death or serious injury, disconnect battery cables (negative (-) cable first) before proceeding. (00307a)
WARNINGDisconnect negative (-) battery cable first. If positive (+) cable should contact ground with negative (-) cable connected, the resulting sparks can cause a battery explosion, which could result in death or serious injury. (00049a)
| 1. | See Figure 1. Follow the instructions in the owner's manual to remove the seat and any other components (side covers, etc.) necessary to provide access to the battery. | |
| 2. | Refer to the correct view in Figure 1 for your model. Break the battery negative (-) connection by removing the hardware assembly from the negative battery terminal. | |
| 3. | Break the positive (+) battery connection by removing the hardware assembly from the positive battery terminal. | |
| 4. | Clean the battery terminals and cable connectors using a wire brush or sandpaper to remove any oxidation. NOTE For 2006 and Later FXD (Dyna) Models: The Battery Charging Harness must be routed through the back of the battery tray before connection to the battery. See the Harness Routing section for details. | |
| 5. | Apply a light coating of Harley-Davidson electrical contact lubricant (Part Number 99861-02), petroleum jelly or other corrosion retardant material to the battery terminals, cable connectors, Battery Charging Harness ring terminals and connector located under the weathershield cap. | |
| WARNING Connect positive (+) battery cable first. If positive (+) cable should contact ground with negative (-) cable connected, the resulting sparks can cause a battery explosion, which could result in death or serious injury. (00068a) | ||
| 6. | Refer to the view in Figure 1 used for disassembly. Install the positive (red) lead of the Battery Charging Harness to the positive (+) battery post in the sequence shown. Tighten the positive (+) terminal post bolt to the value shown in the owner's manual. | |
| 7. | Attach the negative (black) lead of the Battery Charging Harness to the negative (-) battery post in the sequence shown. Tighten the negative (-) terminal post bolt to the value shown in the owner's manual. |

Harness Routing
NOTICE
When routing wires and harnesses, verify that they are clear of moving parts, heat sources and pinch points to avoid wire damage or a short circuit, which could result in electrical system damage. (00579b)
The following sub-sections show the correct harness routing for many models. Whether your specific application is shown or not, be sure to follow these general guidelines:
- Do not tie off the harness end to the fuel tank vent hose.
- Avoid vehicle components that could pinch or cut the harness.
- Keep the harness away from vehicle components that radiate heat.
- Take up any slack in the cable and store out of sight.
- Secure the harness with cable straps (Part Number 10006), available from a Harley Davidson dealer.
VRSC (V-Rod) Models
- See Figure 2. Route the battery harness connector (3) toward the front of the motorcycle following the upper left frame tube. Cleanly tuck the in-line fuse (2) into the space in front of the battery.
- Continue to route the harness connector to the front of the vehicle and behind the vent cover. Secure the harness with a cable strap and let the connector protrude past the cover for easy access. Trim any excess from the cable strap.
- Proceed to ALL Models, Step 4.

- See Figure 4. Route the harness connector (4) toward the rear of the motorcycle following the upper left frame tube. Cleanly tuck the in-line fuse into the space on the side of the battery.
- Locate the B + (battery positive) connector (unused gray connector with a red wire) on the main electrical harness, routed under the seat beneath the ignition control module (5). Secure the Battery Charging Harness connector close to the B + connector with a cable strap (3). Trim any excess from the cable strap.
