If your HS400ATV is not powering up even with a fully charged battery and you've already replaced the ignition switch, there may indeed be another module or component that could be causing the issue. Here are a few possibilities to consider:
1. Main Fuse: Check the main fuse for the ATV. It is typically located near the battery or within the fuse box. Ensure that the fuse is not blown and is making proper contact. A blown main fuse can prevent power from reaching the ignition switch and other electrical components.
2. Starter Solenoid: The starter solenoid is responsible for engaging the starter motor when you turn the ignition key. If the solenoid is faulty or not functioning correctly, it can prevent the ATV from powering up. Inspect the solenoid for any signs of damage or loose connections. Consider testing the solenoid or replacing it if necessary.
3. Kill Switch/Safety Interlock: Check if there is a kill switch or safety interlock feature on your ATV. These safety mechanisms are designed to prevent the ATV from starting under certain conditions, such as when the brakes are not engaged or if the ATV is not in neutral. Make sure these switches are in the correct position and functioning properly.
4. Wiring and Connectors: Inspect the wiring harness and connectors for any loose, damaged, or corroded connections. Pay close attention to the connections between the battery, ignition switch, and any other modules or components. Clean and tighten any loose connections, and repair or replace any damaged wiring or connectors.
5. Electronic Control Module (ECM): The ECM or other control modules could be a potential source of the issue. These modules control various electrical functions in the ATV. However, diagnosing and testing these modules often requires specialized tools and knowledge. It may be best to consult a professional ATV mechanic or an authorized dealer who can properly diagnose and test the modules if needed.
If you've checked these possibilities and the issue still persists, it is recommended to seek professional assistance. They will have the expertise and equipment necessary to diagnose and resolve electrical issues specific to your HS400ATV.

or learn to find shorts like pro.
box of fuses.
unplug all or 1 by 1 all connected devices to the harness
if one device ends fuse blown, bingo. it is a shorted out device
if at the end of all this work , and it still blows fuse
then the harness is shorted, and just inspecting every inch of the harness finds that. short. (see actual damage to it you will)

Clogged Fuel Filter: A clogged fuel filter can cause a lack of fuel flow to the engine, leading to stalling. Even though the fuel pump and regulator were replaced, it's possible that the fuel filter may still be clogged or dirty. Consider replacing the fuel filter as a troubleshooting step.
Faulty Ignition System: If the ignition system is faulty, it can cause the engine to stall. This could be due to a number of reasons, such as a failing ignition coil or spark plug. You may want to have the ignition system checked by a mechanic.
Air Intake Issues: Problems with the air intake can also cause stalling. A clogged air filter, for example, can restrict airflow to the engine and cause stalling. Make sure to check the air filter and clean or replace it if necessary.
Electrical Issues: Electrical problems, such as a faulty sensor or loose connection, can also cause stalling. You may want to have the electrical system checked by a mechanic.
Fuel Injectors: The fuel injectors may not be working properly, which can cause stalling. Have a mechanic check the fuel injectors to ensure they are functioning correctly.
A flashing battery light while driving on your Polaris 700 EFI could indicate a problem with the charging system. Here are a few possible causes:
Faulty alternator: The alternator is responsible for charging the battery while the engine is running. If the alternator isn't working properly, the battery won't receive a sufficient charge and the battery light may flash.
Loose or corroded battery connections: If the battery connections are loose or corroded, the battery won't be able to receive a full charge from the alternator.
Failed voltage regulator: The voltage regulator regulates the output of the alternator. If the voltage regulator fails, it can cause the battery light to flash.
Failed battery: If the battery is failing, it may not be able to hold a charge even when it's being charged properly.
It's a good idea to have your Polaris 700 EFI checked by a professional mechanic to diagnose and fix the problem.
The loud rattle that you hear when the cooling system turns on and when you turn the wheels may be caused by a few different issues. Here are a few possibilities:
Loose or damaged components: It's possible that a component in the front of your Polaris Sportsman, such as a fan blade, is loose or damaged and is causing the noise when the cooling system turns on. Check all components in the front of the vehicle to make sure they are secure and not damaged.
Loose wheel or steering components: The noise may also be caused by loose wheel or steering components, such as a wheel bearing, tie rod end, or ball joint. These components can become loose over time and can cause a rattle or clunking noise when driving or turning. Check these components for wear or damage and tighten or replace them as necessary.
Engine or transmission issue: It's also possible that the noise is coming from the engine or transmission and is being amplified by the cooling system turning on. Have a mechanic inspect the engine and transmission to determine if there are any issues that need to be addressed.
It's important to address any unusual noises in your vehicle promptly to prevent further damage and ensure safe operation. If you are unsure of how to diagnose or repair the issue, it's best to seek the help of a qualified mechanic.
1. Park your mule on a level surface and remove the drain plug from the bottom of the radiator using a socket wrench. Drain the coolant into a pan or onto the ground.
2. Remove the radiator cap and top off the radiator with fresh coolant to the level indicated on the side of the tank.
3. Install a new coolant filter on the coolant lines.
4. Add the appropriate amount of coolant to the radiator and make sure that the level is where it should be.
5. Reinstall the radiator cap and drain plug, then start the engine and let it run for several minutes to allow the new coolant to flow through the hoses.
6. Let the engine cool, then check the coolant level again. Add additional coolant if necessary.
7. Replace the coolant filter once a year to ensure that your engine stays in top condition.
The most likely cause of this issue is that the starter solenoid is bad, or the connection between the starter solenoid and the starter is loose. Check the connections and make sure they are tight. If the problem persists, the starter solenoid may need to be replaced.
no year[s] given yes their are fuses and battery fuse newer have a breaker -----do online search using year make and model for service manual[s] most polaris atv manuals are available free pdf online this one is an example ------------------ https://www.manualslib.com/products/Polaris-Trail-Boss-325-5904729.html
The fuse box on the 2004 Sportsman 500 HO should be located under the hood, near the battery. On the left side of the battery box, look for an access panel with a fuse cover. This cover will provide access to the fuse box.
The fuse box should be located near the battery. It is usually near the front fender. The cover should have a diagram of the fuse layout, which should tell you what fuses are located in the box.
