Fuses prevent your car’s electrical systems from overloading by blowing if the electrical current gets too high. Before looking into the issue further, check and replace the matching fuse if one of your Toyota’s electrical system’s components isn’t working properly. A charging system fuse in Toyota systems creates a connection between the alternator and the battery. You don’t need any special equipment or knowledge to remove, inspect, and replace this fuse.

Step 2
The auxiliary catch lever is under the center of the front of the hood; pull it to raise the hood. The hood support slot should now accept the hood support rod.
Step 5
Find the “ALT-S” fuse on the fuse diagram. The fuse diagram is a sticker that typically hangs from the top or bottom of the fuse box cover and indicates where each fuse is situated inside the fuse box. The charging system fuse is marked “ALT-S.”
Step 6
In the fuse box, look for the tool for removing fuses. A plastic pair of tweezers with a plastic clip serve as the fuse removal instrument. To remove the plastic clip, pull the fuse removal tool off of it.
Using the fuse removal tool, grab the top of the “ALT-S” fuse and pull it straight up out of the socket.
How is a fuse changed in a Toyota?
In conclusion, the following are 12 easy steps for changing a fuse in a car:
- Set the battery cable free.
- Locate the fuse box for the car.
- Uncover or remove the fuse box lid.
- Cut off the fuse box’s power source.
- Take the fuse box housing off.
- the fuse puller or the blown fuse
- Before removing the faulty fuse, test it.
- Take out the blown fuse.
- Put in a replacement fuse with the appropriate amperage.
- Reattach the system’s cables
- the ignition, then test
- For problems that are not remedied or keep happening, speak to a qualified mechanic.
What happens if the fuse for the alternator blows?
The alternator won’t be able to charge the battery if the fuse or fusible link is blown. As a result, the battery is unable to store enough energy to start or maintain the vehicle.
Can a blown fuse drain the power in a car?
An electrical conduit is a fuse. Simply said, a headlight or turn signal won’t work if a fuse blows.
It may occasionally result in an open circuit that drains energy. Other potential causes include a blown fuse that produces a parasitic drain on the battery (think of a glove box light that wont turn off). The battery may also be discharged by a relay switch that is trapped in the ON position.
Test the battery and use a fuse tester to find the issue. The most likely cause of your issue is either a poor battery or even an inside light that was left on.
Although buying a car can be pricey, insurance doesn’t have to be. Try using the Jerry app to compare prices after replacing your blown fuse. The typical user reduces their annual auto insurance costs by more than $800. Consider how many petrol tanks you could purchase with that money!
How can I fix a non-charging alternator?
To verify the operation of your alternator, you can follow a few simple procedures.
- While the engine is running, gently tap the alternator with a hammer; if the charging returns to normal, the carbon brushes within are worn out and require replacement.
- Examine the huge power connection going to the alternator as well as the nearby battery’s typically large 40-60 amp fuse.
- Between the engine and the body, inspect the ground cable.
- Verify the alternator is rotating along with the engine and the serpentine belt is in place.
- Examine the charging light wire and the little power supply wire. You can measure it with a multimeter, but to do it correctly you might need a wiring diagram and some knowledge of car electronics.
- To make sure they are not harmed, you can measure the voltage regulator and the diode assembly. Although some alternators can be used to replace these, buying a new alternator these days is frequently the same cost. What you decide is more worthwhile is entirely up to you.
A blown fuse could stop an automobile from starting.
Have a mechanic examine your vehicle because you may need to replace the alternator if it is damaged. It’s best to get it checked out as soon as possible because sometimes it might even harm your car’s battery.
What can you do about it?
Check to see if your automobile will start after shifting into neutral. Attempt depressing the brake pedal as well.
Clutch your vehicle’s manual transmission by depressing the clutch pedal.
A malfunctioning neutral safety switch, which can be quite dangerous, may be the cause of your automobile starting even if it is in drive, starting just in park instead of neutral, or starting in park but not neutral.
Faulty Fuse
Car fuses are essential safety equipment for any vehicle’s electrical system. Your automobile won’t start if something is broken or the fusible linkages are damaged.
The starting relay, which is required to supply the spark, the ignition, and the power to drive your car, might be cut off by a faulty or blown fuse.
To find the fuse box in your car, start by consulting the owner’s manual. Next, look for a blown fuse or any obvious wire damage.
If you see it, tow your vehicle to a shop to get the fuse changed. As an alternative, you can request a mechanic to visit your driveway and fix it!
Issues With The Ignition Switch
Your automobile won’t start if the switch is broken since there is no electricity to the starter motor or ignition system.
The ignition switch can malfunction even if it isn’t the most frequent reason for your car to stall.
Your car will indicate this by displaying signals like these:
- The car won’t turn on
- The car key is stuck.
- The starter motor won’t produce any noise.
- The dashboard of the car could flash.
- The instrument panel might not be illuminated.
Another indication of a broken ignition switch is if your ignition switch is constantly in the on position, continuously operating the fuel pump.
Carrying a keychain with fewer keys is the easiest method to handle a faulty ignition switch.
Given that the ignition switch is located directly behind the ignition lock cylinder, a bulky keychain could strain the switch when you enter the key (the place where you insert your car key).
Get in touch with a mobile car repair service to have it addressed right away if you’re certain that the issue is with the ignition switch rather than the battery or alternator.
Dead Key Fob Battery
If your push-start system car’s engine won’t crank when you click the Start button, your key fob might be malfunctioning or dead.
Your car won’t start if the key fob battery is dead since the button won’t get any signals from it.
Simply replace the battery in the dead automobile key fob. To open the battery cover, use a coin or a tiny screwdriver. A silver coin or button will resemble the battery.
Find the battery’s serial number and purchase a replacement battery that matches it. Request assistance from a mechanic if it doesn’t operate after that.
Bad Starter Motor
An internal combustion engine’s starter motor turns the engine to enable it to start working on its own.
It is connected to a starter solenoid, a tiny cylinder-like part that carries electrical current from the battery to the starter motor in order to start the car’s engine.
When you turn the ignition key on, your car won’t start if the starter motor or starter solenoid are damaged.
So how can you know if your starter solenoid or motor is damaged? These indications:
- The engine of your car won’t start.
- It’s possible that your engine cranks very slowly.
- You can hear a grinding or whirling noise when starting the automobile.
You may need to get your starting or starter solenoid replaced by a mechanic if you observed any of these symptoms.
Bad Spark Plug Or Broken Distributor Cap/Rotor
To start the combustion system, your car needs the proper air-fuel ratio (fuel pressure) and spark.
If your car won’t start despite having a healthy battery and enough gas in the tank, you probably have a bad spark plug.
Here’s how to recognize a faulty spark plug:
- Significant drop in fuel efficiency
- accelerating problems
- engine stalls
- erratic idling
Describe them. A distributor controls the flow of power to the spark plugs that ignite the fuel. It sends spark plugs a high voltage current coming from the ignition coil.
It contains a revolving arm or rotor inside a distributor cap, which serves as a cover to safeguard the distributor’s internal components. The contacts between the internal rotor and the spark plug wires are likewise kept in place by the cap.
Now, the spark won’t travel if the distributor cap isn’t on firmly or the rotor isn’t operating correctly.
Bad spark plug symptoms are difficult to identify and frequently coexist with problems with other car parts. It’s better to have a qualified mechanic check your car to see whether the ignition coil, distributor cap, or spark plugs are damaged.
Timing Belt Needs Replacing
An internal engine part is the timing belt. Your engine’s crankshaft and cam are rotated at the appropriate times by a rubber strip.
Your car’s engine won’t run if it malfunctions. The starter motor may turn on but not turn over, or you may even hear a ticking noise coming from underneath the hood.
A timing belt can rupture while the car’s engine is operating, which is a less common problem but can harm the engine.
The only way to remedy a broken timing belt is to have a mechanic replace it.
A timing chain may be installed in some vehicles in place of a timing belt. Typically, it outlasts the rubber belt. However, you will still need to call a mechanic to fix a broken timing chain.
Not Enough Gas In The Fuel Tank
It might seem simple, but if your battery, spark plug, and alternator are in good shape, you should check to see if your automobile has adequate fuel.
Before you start driving, check that your gas tank has enough fuel, and make an effort to keep it filled up.
During the winter, a fuel line in your car could even freeze. Keep in mind that the more space there is for water vapor to condense and freeze inside your car’s gasoline line, the more empty a gas tank or fuel tank there is.
Finally, have your gasoline reading gauge checked if it frequently runs out to the point that your car won’t start. The gauge can be defective and unable to provide you with the appropriate reading at the appropriate moment. Any other underlying problems with the fuel system will also be found by a mechanic.
Clogged Fuel Filter
A fuel filter will eventually become clogged since its duty is to prevent pollutants and other filth from entering the engine.
Now, even if the fuel filter partially clogs, your car will still run. However, you won’t be able to start your car if the gasoline filter is entirely blocked. Due to low fuel pressure, the engine won’t receive any fuel from the fuel tank.
Consult the owner’s manual. The frequency of gasoline filter replacement will have been specified by the manufacturer. Make it a practice to have it replaced by a professional when necessary so that you don’t end up with a seriously clogged fuel filter.
Ground Cable Wiring Problem
The ground cable, which links the negative terminal of the automobile battery to the vehicle’s body, is a thick, black battery cable. It is also referred to as the ground wire, the negative battery cable, or the ground strap.
This battery cable serves as the primary conduit for electricity to almost all of your car’s electrical parts, serving as the backbone of the entire electrical system.
Your automobile won’t start if there’s a problem with it since the power flow will be interrupted. This suggests that the engine power won’t be able to start the engine in your car.
How can you detect if a ground cable issue is present? Here are a few typical signs:
- dome light that is dim or flickers
- faulty fuel pump
- Finished battery
- intermittent sensor failure
- electricity switching on and off
- Slipping clutch in the AC compressor
- damaged cables or the throttle
- tough beginning
Open the hood to visually check for a damaged ground cable. You will need to replace it if it appears to be worn out.
Without a fuse puller, how can a fuse be removed?
A pair of tweezers might work. Look for tubular glass that has a black inside or that no longer has its filaments intact if you notice any. Use a bent paper clip or a small pair of pliers if you are unable to get it out with your fingers.
