Have to charge the battery once a week i have replaced the battery and still have to charge it

The primary requirement apart from a healthy charging system is a healthy battery and it is the problem with little used vehicles and other battery powered equipment is few people remember to periodically charge them - a battery will self discharge over time and when connected to a vehicle with an electronic system that is always "on", the discharge rate will be greater.

A battery that is left partly or completely discharged for even a few weeks will be permanently damaged or completely ruined.

As a matter of diverse interest, a vehicle "charging" system is a massive misnomer as firstly it isn't designed to recharge a battery but to keep a fully charged battery fully charged (and usually doesn't do that very well) and because of the design of the system, the "charge" rate quickly drops to a trickle charge and few people drive constantly for the large number of hours it takes to recharge a battery that is being trickle charged - a large car battery can take a week or longer...

First remove the battery, charge and test it...

battery failing

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.

By everything, I am assuming you mean the charge coils, regulator/rectifier and the battery? Then all you are left with is wiring. Bad charge coils means low or no output. Bad regulator/rectifier can mean either the regulator prevents the charge from getting to the battery or the rectifier is bad and dumping charge to ground or sending AC (Alternating Current) into the battery, which will kill it is short order. If there is no water in the battery or the plates are shorted, it will not accept a charge.

Could be time to replace battery, this is most likely the culprit. These fourwheelers are very picky when it comes to low power. Your starter is also most likely just fine, the clicking you hear is the solenoid on the starter, so your battery has some juice, but not enough amps to turn over the starter. Also If the fourwheeler has sat for a long time then you may just need to charge the battery. The 2007 is most likely fuel inject which uses even more fuel when running and it also has its own computer kind of like a PCM in a car or truck. These all need a good supply of power and the stator which is like an alternator usually needs the help of a fully charged battery to keep everything running properly. Also note, once you get a new battery or charge it in some cases the ATV should run smoother.

It could be your battery not being fully charged or possibly dirty fuel.

replace starter

Kawasaki mule 610 new battery but little to no power to solenoid. Fully charged starter makes rapid clicking noise. When attacked to battery jump starter it will start. Mule was running excellent for 2 weeks with new battery. I was told by kawasaki technician it was ignition. Nope thoroughly skimmed inspected wires and see nothing wrong. Technician told me different second time, it's now the starter replaced starter ($450) and still no results I'm at a loss

Hey Ccp.. A new battery and it did not help the cranking issue?? hhmm... PLEASE take the battery and have the CCA (Cold Cranking Amps) checked... just because its new and has voltage does not mean its a "good battery"... It takes AMPERAGE to crank and run your machine.. (*see 35 amp fast charge!!)..Autozone, O'reilly's, a battery shop can check the CCA... once you have MADE SURE the battery is good, then you can proceed to diagnosing the real issue...This is the procedure a professional mechanic takes..so do this first... once you have determined the battery is (good or you got a new one)..and ... once you have the machine running,,WITHOUT a charger hooked up.. time to check the output.. you should get 13.5+ volts at 3000+rpm.. if you are not getting 13.5+ volts, its time for electrical diagnosis...This manual should have all the electrical specifications needed to diagnose your issues...
