IS THE SPARK PLUG WIRE CONNECTED?

hi there this sounds like a earth problem check each indicators earth connectors

it takes a 428 chain ,im not sure how long but get. 120 links and cut it down if you need to.

the variator is probably stuck as the rollers wear and either fall out in there and jam it up or wear into the side of the ramps.does it go ok on a straight?

Mark, your bike should have a main fuse very close to the battery check it, sounds like it's blown

It must have a plug (17 mm) under the right side of the engine and on the same side but on top of the engine there must have the plug to fill up (black plastic with a dipstick).

That sounds like it'll be the indicator relay matey if they were just on and not flashing.

It may be that the whole headlamp unit has dropped (at the front) so it all points down slightly, if it has a bolt on each side (where it mounts)these may be loose. Firmly try to pull the whole headlamp unit upward, if it moves, tighten the 2 bolts whil its in the correct position.

Some common causes and potential solutions: Air/Vacuum Leak: If your Harley develops a vacuum leak in its air intake system, the air-fuel mixture becomes too rich. This can cause frequent stall outs, especially after the bike warms up. Vacuum leaks often occur due to dried-out or cracked air intake boots, faulty gaskets, or worn-out carburetor seals. When air escapes from the intake system, the fuel fills the empty space in the combustion chamber, altering the air/fuel ratio and negatively impacting combustion. Severe vacuum leaks can lead to excess fuel flowing into the exhaust system, causing backfiring and stalling while riding. Clogged Fuel Tank Filter/Fuel Injectors: A blocked fuel tank filter (due to coagulated fuel, moisture, dirt, or corrosion) impairs fuel flow, resulting in a lean air/fuel ratio. On fuel-injected Harleys, clogged fuel injectors produce similar symptoms. Regular maintenance, including cleaning and inspecting fuel filters, helps prevent these issues. Faulty Cam Chain Tensioner: A malfunctioning cam chain tensioner can affect engine timing and cause stalling. Regular checks and replacements are essential to avoid this problem. Faulty Cam Position Sensor: The cam position sensor plays a crucial role in ignition timing. If it malfunctions, it can lead to stalling and backfiring. Clogged Air Cleaner: A dirty air cleaner restricts airflow, affecting combustion efficiency. Regularly clean or replace the air filter to prevent this issue. Ignition System Failure: Faulty ignition components (such as spark plugs, ignition coils, or wires) can cause misfires, backfires, and stalling. Inspect and maintain these parts regularly. Compromised Battery Terminal Connection: Poor battery connections can disrupt electrical flow, affecting the ignition system. Ensure clean and secure battery terminals. Remember that diagnosing and addressing these issues may require professional assistance. Regular maintenance and timely repairs can keep your Fat Boy running smoothly on the road.

I can't find a diagram. The small potentiometer on the control board likely serves as an adjustable component to fine-tune specific parameters. Here are some possibilities: Voltage Regulation: The potentiometer might control the output voltage. By adjusting it, you can set the desired charging voltage for different battery types (e.g., 6V or 12V). Current Limit Adjustment: It could be used to set the maximum charging current. Adjusting the potentiometer allows you to limit the charging current based on the battery's capacity and condition. Sensitivity or Threshold: Some potentiometers act as sensitivity controls. For example, it might adjust the threshold at which the charger switches between charging and maintenance modes. Setting the Potentiometer: Without the specific circuit diagram or detailed information about your charger, I recommend the following general steps: Observe the Potentiometer: Identify the potentiometer on the control board. Note its position and any markings (if present). Consult the User Manual: Check the user manual or operating instructions. It might provide guidance on adjusting the potentiometer. Trial and Error: If no specific instructions are available, start with the potentiometer set to its mid-position. Gradually adjust it while monitoring the charger's behavior (e.g., charging current, voltage). Observe how the charger responds to changes in the potentiometer setting. Fine-tune it based on your specific battery type and desired charging characteristics. Remember that precise adjustments depend on the charger's design and the battery you're charging.
