How To Solve The Honda Civic Electrical Problems?

In today’s modern world, we have become well equipped to accomplish the things, and there are many new technologies coming up every day. There are so many auto electrical systems that are getting complicated with the fast growing world of technology. Yes, we are talking about the Honda car and electrical problems associated with it.

Honda Civic electrical problems can be among the most expensive and frustrating to figure out and repair. But if you have access to a multimeter and learn a bit about the battery, you should be able to diagnose the problem. You might even be able to fix some problems yourself with the proper knowledge.

Have you every been stuck somewhere in the middle of the road while driving your Honda Civic? Have you ever faced electrical problems with your car? Some people get stuck because of transmission failure, exhaust manifold cracking, or the engine block issues.Although, electrical issues can also stop your Honda and leave you stranded.

This guide can be helpful for you if you have some electrical issues that we will discuss in this article. We will mention precautionary tips that you should consider while driving Honda car.

Every car is prone to electrical problems and the the Honda Civic is no exception. Users may experience issues such as a dead alternator, complete car shut down, blown speedometer fuse, battery issues, and problems with tail lights. This guide helps the reader to know about a few common Honda Civic electrical problems in detail.

Here we have listed some troubleshooting tips, have a look:

If you are have a Honda Civic, then you should know about the possible electrical problems associated with it as mentioned earlier. Prior knowledge can help you avoid getting stranded. Some DIY steps are required to maintain the various important parts of the car. Here are some troubleshoot tips mentioned below:

Honda Battery

The battery is considered the heart of the car. It supplies the power to perform various tasks such as self-start functionality and operating various electrical equipment (lights, turn signal indicators, horn, etc.).

The battery in Honda Civic is usually a 12 Volts six cells battery. A regular car battery will have cells that are stacked with lead plates that have a positive and negative end. If the battery is damaged, connected incorrectly, and or charged incorrectly, problems will occur.

That's why getting into a fender bender may seem like it's no big deal, but it's always a good practice to check the battery after an accident. You should look to see if the electrical connections are intact as well.

If a battery gets cracked a leak can occur. A leak can cause acid to drip onto car parts. The lead plate and electrolytes can starts reacting to produce harmful hydrogen gasses that could also leak. These gasses can cause an explosion if there is a spark. 

Sometimes Honda Civic electrical problems occurs when a battery dies or the battery terminals are corroded. These batteries can fail without warning if they are defective.

You should clean the corrosion and ensure your battery terminals are tight if your car doesn't start or the lights seem dim. If battery terminals are not tight, then it may be the cause of your car not functioning well.

  • If they are clean, use a voltmeter by touching the probes to plus and minus posts of the battery. You can scratch it slightly to ensure a good connection.
  • If voltmeter reads between around 12.6 volts after switching off the engine and ignition, then the battery is probably good. Be sure to check it after sitting all night.

Whenever you feel your Honda Civic electrical problems are associated with the battery of your car, you should immediately get it checked. If the battery is low (about 12.4 volts or less) you'll also need to check the alternator to see if it is charging your battery. Older batteries tend to loose their charge and eventually will stop working after 3 or more years.

Honda Alternator

Honda-Alternator

The alternator is used to produce electricity and maintain the battery's charge. It helps run all the electric accessories of Honda Civic car. The alternator is belt-driven and is turned by the car's engine. It produces alternating current. The alternating current needs to be changed into direct current, so it can be stored in the car battery.

To get the correct current into the battery, the alternator uses a diode to convert AC to DC (direct current). The alternator is also used to maintain the ideal voltage of system by making use of internal voltage regulators in the car.

You find out if you have alternator problems by using the multimeter that if connected to the battery terminals and turning the car on. If your multimeter shows about 14.4 volts, it is working well. But if your multimeter shows about 14.0 (or less) then you may want to check the drive belt to see if it is working well.

If your multimeter shows about 15.0 (or more) volts your alternator may have a problem with the alternator voltage regulator. Usually the alternator will need to be replaced. 

Make sure all your accessories and lights are turned off when you check the mutlimeter. You can also keep the ignition switch in the “ON” position to check for any dashboard warning lights. These can indicate problems with an electrical circuit. Check the warning lights whenever you find engine doesn’t start well.

If you don't have a multimeter there are several kinds of phone chargers for the car that show car battery voltage when the car engine is off and on. Here's what mine looks like when I use my car.

If alternator doesn't seem to be working or you see a warning light, you should follow the these tips:

  • You take a look at the wiring on the Honda alternator.
  • You should make sure the wires are connected well. 

If you find that warning light on the dashboard comes on then, it may indicates that alternator’s wiring is working, but the wire going to the battery is damaged or loose

If your Honda Civic is idling for a long period during high temperatures, this may cause low output from the alternator. Here are some things to consider below:

alternator
  • The electrical resistance of alternator rises with heat, and it reduces the charging capacity of the alternator.
  • When the temperature rises it to cause reduction of voltage and also reduces the chances of overcharging the battery.

Fusible Link

A fusible link is a higher capacity connector that helps protect accessories wired directly to the battery, such as the starter. This connector can sometimes fail suddenly or gradually. You can easily find out the cause of a failing fuse link by checking electrical accessory operation, such as shown in the video above, and an unusual pause before the starter turns.

If you find the battery cables are tight and electrical system is dead, then it may indicates that fusible link has burned up. For replacement, you need to get a proper repair manual for your car or see if the above video can help. You'll need to check all the connections so you know which cables need to be replaced. Get help if needed. 

Faulty Switches

You'll need to test the switches, such as a power switch to operate the window, windshield wipers, etc. If it sometimes works, you may have a loose connections,

Sometimes you'll need to check the fuse box for the appropriate electrical accessory to see if a fuse needs to be replaced. Some switches in a car can have built-in circuit breakers, so consult your repair manual or consult a mechanic on how to reset the breaker.

Maintain Ace Tips for Honda Civic Car

  • Install the best car accessories: most Honda car users suggest high quality car accessories.
  • You should use synthetic oil for your engine so your car can last for a long time.
  • You should see that your car is served with coolant to avoid issues associated with overheating.
  • The electric system of Honda Civic car requires complete checkup and tests every once every 2 years. You should get it checked whenever you go for a car service if experiencing any issues.
  • Some driving problems are caused by variation in voltage, so troubleshooting electrical problems may help solve driving problems too.
  • The electric system of the car should be tested for voltage for your vehicles specified standards. The drop voltage can be checked with a mutlimeter (see video) to check the functionality of different electrical parts, such as the alternator. 
  • Apart from multimeter testing, you should get the help of an expert automobile technician who has proper knowledge about your electrical system when needed.

Conclusion

It can be a big deal for the Honda user to deal with the electrical problems. I hope these tips and knowledge may help you in avoiding any electrical problems. A few checks can help you solve your electrical problems and get back to your regular driving routine.
