Have you ever gone to start your ATV, only to find that your atv won’t start unless jump solenoid? If so, you’re not alone. This is a common problem that can be caused by a number of different things.
In this blog post, we’ll take a look at some of the possible causes of this problem and what you can do to fix it. We’ll also provide some troubleshooting tips to help you get your ATV up and running again as quickly as possible.
What is a solenoid?
Solenoids are devices that use an electromagnetic field to generate a force. They are found in a variety of applications, including door locks, starters in cars, and valves in sprinkler systems.
When a solenoid is used to actuate a door lock, it generates a magnetic field that interacts with the door’s locking mechanism. This interaction creates a force that opens or closes the door.
In car starters, solenoids are used to engage the starter motor with the engine. When you turn the key to start your car, current flows through the solenoid and creates a magnetic field. This field interact with the starter motor, causing it to spin and start your engine.
Valves in sprinkler systems are also actuated by solenoids. When water pressure is high enough, current flows through the solenoid and creates a magnetic field. This field interact with the valve, causing it to open and allow water to flow through.
Why my ATV Won’t start unless jump solenoid?
There are several reasons why an ATV won’t start unless the solenoid is jumped. The following are some of the most common causes:
1. Bad Solenoid
The solenoid is a small electrical component responsible for transmitting electrical currents from the battery to the starter. When the starter button is pressed, the solenoid creates a magnetic field, which engages the starter motor. If the solenoid is bad, the ATV won’t start without jumping it.
How a Solenoid Works
The solenoid is designed to act as a switch. It is connected to the battery and the starter motor. When the key is turned on and the starter button is pressed, the solenoid receives an electrical signal from the battery.
The solenoid then creates a magnetic field that pulls a small plunger, which completes the circuit between the battery and the starter motor. This action causes the starter motor to engage and turn the engine over.
Symptoms of a Bad Solenoid
If the solenoid is bad, the ATV won’t start without jumping it. Additionally, you may hear a clicking noise when you try to start the ATV, or the starter may spin without engaging the engine.
Reasons Why a Solenoid May Fail
The solenoid may fail due to various reasons, including wear and tear, a corroded or loose connection, or an electrical short.
How to Test a Solenoid
To test the solenoid, you need a multimeter. First, disconnect the battery. Then, disconnect the wires from the solenoid. Place the multimeter probes on the solenoid’s terminals and press the starter button. If the multimeter reads 12 volts, the solenoid is good. If not, the solenoid needs to be replaced.
2. Weak Battery
The battery is responsible for providing the electrical energy to start the ATV. If the battery is weak, the ATV won’t start unless the solenoid is jumped.
How a Battery Powers an ATV
The battery stores chemical energy and converts it into electrical energy. This energy is then used to power the ATV’s starter motor, ignition system, and other electrical components.
Symptoms of a Weak Battery
A weak battery may cause the ATV to crank slowly or not at all. You may also notice dimming headlights or other electrical components.
Reasons Why a Battery May Become Weak A battery may become weak due to various reasons, including age, excessive use, and low electrolyte levels.
How to Test a Battery To test the battery, you need a battery tester or a multimeter. First, turn off the ATV and disconnect the battery. Connect the battery tester or multimeter probes to the battery terminals. If the voltage reading is below 12 volts, the battery is weak and needs to be charged or replaced.
3. Loose Connections
Loose connections between the battery, solenoid, and starter motor can cause the ATV not to start unless the solenoid is jumped.
How Loose Connections May Cause the Issue
When the connections between the battery, solenoid, and starter motor are loose, they may not be able to transmit the electrical current needed to start the ATV.
Symptoms of Loose Connections
Symptoms of loose connections include difficulty starting the ATV, dimming headlights, and other electrical issues.
How to Check for Loose Connections
To check for loose connections, first, make sure the ATV is turned off and the key is removed. Then, check the battery connections for corrosion or looseness. Next, check the connections on the solenoid and starter motor for tightness. If any connections are loose, tighten them and try starting the ATV again.
How do I fix this problem?
If your ATV won’t start unless you jump the solenoid, there are a few things you can check. First, make sure the battery is fully charged. If it’s not, charge it and try again. If the battery is charged, check the connections to make sure they’re clean and tight.
If those things don’t work, it’s possible that the starter itself is bad. You can test this by jumpering the solenoid directly (bypassing the ATV’s electrical system entirely). If the ATV starts this way, the problem is in the ATV’s electrical system – not the starter.
Once you’ve determined where the problem lies, you can take steps to fix it. If it’s a bad connection, clean and tightens all of the connections. If it’s a bad starter, you’ll need to replace it.
If your ATV won’t start unless you jump the solenoid, there are a few things that could be causing the problem. It could be an issue with the battery, the starter, or the solenoid itself.
If you’re not sure what’s causing the problem, it’s best to take it to a mechanic or ATV specialist to get it checked out. In the meantime, try jumper cables to see if that helps get your ATV started.
