Um dtf 110 fuel hose loose

Sounds like the carb overflow hose. It it's leaking gas the float in the carburator is stuck and letting too much gas into the float bowl, causing the excess gas to drain from this hose. You will have to remove the carb and set the float to the proper level.

No brake light

Check to see if the bulb is blown or the connections are rusty or loose. Normally accessed by unscrewing the two Philip Head Screws in the lens. A lot or motorcycles have poorly designed taillight waterproofing and this will allow water to get in, rusting the connections. Check for loose or broken wires. Check for holes in the lens. The rubber seal around the lens often gets wreaked by vibration and or sunlight and needs replaced. If there is water or moisture inside, find out why. If the seal is OK try appling some petroleum jelly (Vaseline) to aid waterproofing. Don't forget to clean the lens while it is apart to save taking it off again.

I have a Renegade 200 and it Starts but won't

Try shifting into gear when the motor isn't running. If it goes into gear check your clutch adjustment; if the clutch remains partially engaged you wont be able to get it into gear.

My bike will start but

Does it shift into gear when the bike is turned off? If it does, the clutch isn't completely engaging and probably needs an adjustment.

What causes my fat boy to idle just fine but fall on its face back fire and try to shut down while riding

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.

Need circuit diagram for ARLEC 15e 6-24Volt 15Amp Electronic battery charger OR their later model BC58

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.

What is the length of lift cables on a 1993 model 2693 hilo camper and any info on what after market part to use ? thanks

The lift cables on a 1993 model 2693 Hilo camper are 30 feet,2 3/4 inches long and fit the standard height lift of 11 feet 8 inches high to the top of the overhead. The lift uses two cables. According to a Hi- Lo camper travel trailer forum, cable replacement is basically the same on all years and models, with the main difference being the length of the cables from model to model. You can use a cable cut chart to find what cable length you need for your camper, and you'll need to know your year, model name, and box (body) length: Lift cables typically wear out after three to five years, so it's important to replace them as needed and keep them regularly maintained.

Mine is a 410JS 1000cc Santana, Spanish made. Mechanical fuel pump does bring no fuel to the carb. Want to shift to an electric setup. What is the best pump? Do I need an overflow-line?

The bike doesn't exist as written. https://www.google.com/search?q=410JS+1000cc+santana We are better with 'year make model 1000cc'. Better to not try and do better than the bike engineers. A mechanical pump runs when the engine is turning, an electric pump will run as soon as the key is turned and create pressure all the time. It would have to be an in tank electric pump or it will burn out. Electric pumps are cooled an lubricated by the fuel passing through it. If it is a carbureted engine, you are pressurizing the carb bowl. If injected, it may already have a fuel return. Check the mechanical pump for a torn diaphragm, they are easy to change. ..
