Find out what your coil voltage is and tests and see if you're getting the right amount of voltage to the coil and from the coil when it's on and if you're going to need it when it's off the first thing you need is a wiring schematic for 1982 sportster or you could just replace the wires if there be original wires and the coil packs if the be

A partially plugged exhaust will cause it to overheat and lose power. When it stalls, do you still have spark? An ignition coil may fail hot, look for a crack in the plastic.

Your bike is something of a classic and you could find more specialised information on an appropriate bike forum. Presumably it has an ignition module of some sort and with the aid of a wiring diagram all the cables and voltages and connections to and from it should be checked for cleanliness, continuity and power as appropriate. The module connections on my CX500 had corroded and needed a thorough clean.

Dead battery. Recharge or get a new one.

You need a new battery if it wont power up it means the battery wont take/hold charge

Is your battery fully charged? If you have two wave runners, switch the computer from one to the other and try again.

Something is definitely not working here your 0 - 60 should be about 3 to 4 seconds alone and top end about the 120 mark. I would suggest that half your engine is not operating, but why and which half is the question. I would suggest first getting each cylinder checked for compression this will also tell you if any valves are not operating/damaged. If all OK, do all plugs spark if taken out one by one and the threads pressed to the cylinder head (wear a glove for this test). If OK is fuel getting to the carbs and are the carb settings correct i.e. needle position, pilot air screw adjustment, float height etc. is the fuel tank breather blocked? How old is the fuel, old fuel causes engine running problems. Check the air filter do you need a new one or does it need cleaning. An oil change is always good make sure the oil is correct weight your bike probably needs 10W 40 oil (I always use semi synthetic). Hope the above helps.

Depends a lot on what motorcycle you have. There are numerous answers to that question once one know what you have.

Follow the wire from the starter and it will come to a fuse. Check the fuse. If it is good it looks like an "S" if part of it is missing then it is bad. If it was good check for voltage to the fuse while holding the starter button. If not there check the starter relay. It will have a heavy guage wire in and then out but it also has 2 smaller wires that attach to smaller screws check for voltage on one of these wires if it is there and nothing happens when you push the starter button then you have a bad starter relay or ground for the relay.

Check your fuse or battery condition. Could be the bulb also or a bad connection. More info would help.

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.

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.

Check fuel delivery ,or fuel filter

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. ..

Question edited for clarity and add maker. Try cleaning the Throttle Body. This bike works the same as a car.
