Why There is No Power to Dash or Ignition?

You insert your key into the ignition and turn the key to start. The dashboard lights up, but the engine won’t start. However, everything appears to be in order. So you might be wondering about why there is no power to dash or ignition? There are several causes of a car’s dashboard or ignition not working. Here is a very extensive list of potential justifications you might want to think about. Let’s get into it.

Causes of No Power to Dash or Ignition

Following are the possible causes why there is no power to dash or ignition:

  • Bad Alternator

Providing electrical power to various auto parts is one of the alternator’s primary duties. The engine, the ignition, and the dashboard are just a few of the several devices that use this energy. As a result, a malfunctioning alternator won’t be able to supply enough electricity to the ignition or the dashboard.

If the batteries remain sound, the issue can lie in the alternator. If the issue persists, the alternator has to be examined and replaced. You may use a voltmeter to assess your car’s general health, or you can bring it to a technician to have it looked at and fixed.

Solution 

If you hire a professional to replace the alternator, you may have to pay them a few hundred dollars. So follow the steps below to save your money:

To prevent any harm, let the engine cool down. Unplug one of the battery connectors to prevent any harm to the electrical system. Remove the alternator’s electrical connections. The fasteners holding the alternator to the engine must get undone. Remove the outdated alternator.

Before installing the new alternator, make sure the battery is completely charged. Once the battery has charged, reinstall the new alternator.

  • Blown Fuse

A blown fuse is another typical cause of no power to dash or ignition. Any time a fuse in a car blows, it may cause various issues that might impact how well it runs overall, including the dashboards and ignition not working.

Solution 

It is simple to install a new fuse if the old one blows. You’re fine to go if changing the fuse makes the dash lights stay on.

  • Faulty Ignition Issues

A broken ignition switch may cause your car’s total lack of electrical power. The battery receives a signal to start the car when you turn the ignition key and insert the key.

It may deteriorate over time and start acting strangely due to overheating. There won’t be any electricity to the ignition when it malfunctions. While you’re at it, check the ignition relay and see whether your ignition has power.

The dashboard light won’t turn on if the wiring breaks or is damaged. Broken wiring can also disrupt the circuit and finally cause the dash lights to stop working altogether.

It might not be as easy as some people assume to fix a wiring fault that results in no power to the dash and an ignition problem. Therefore, you might wish to engage a qualified technician to evaluate the damage and perform the repairs.

  • Damaged Starter

If your automobile doesn’t have power, but the battery gets charged, you should examine the starter. Your car’s starter is a little motor that pulls electricity from the battery. When the starter malfunctions, you will typically hear a clicking sound. It may occur when some of the connectors become loose or the starter malfunctions. Make that the starter’s wires and fusible connections are in excellent condition.

Follow the steps below:

  • To prevent the battery from powering anything and shorting anything, disconnect the positive connection of the battery.
  • Remove the starter by unscrewing the bolts and holding it in place.
  • If any bolts are challenging to access, use a ratchet wrench with an extension.
  • Remove the starter-connected wires from the starter.
  • The old starter may be removed and swapped out for a new one.
  • Dimmer Switch

If you’ve unintentionally changed the settings on the dimmer switch, it might also be why the dash lights are out when the key gets turned on. This switch manages the brightness of your car’s dash lights.
