Why does my car tick when I try to start it?
A rapid clicking noise when trying to start your car could mean there’s something wrong within the electrical system. Perhaps your battery’s dead, or your alternator, which charges the battery, isn’t working correctly. You may need to replace your alternator or battery.
What gives power to the starter?
The starter motor needs a heavy electric current, which it draws through heavy gauge cables from the battery. The main starter motor power is supplied directly from the positive side of the battery via the positive battery cable. A trigger wire generates an electrical signal which is initiated by the ignition switch.
What happens when there is no power to the starter motor?
If there’s no power to the starter motor but power everywhere else you’d hear a “click!” noise when you turned to start but nothing else – ie. no whirring or cranking noises.
When do you know you have a starter problem?
If your lights are bright with the engine off, but they get really dim when you turn the engine over with the starter, and the engine turns over very slowly, you may have starter problems. If battery terminals get hot along with the battery cable (positive and negative) you probably have starter problems.
How does a starter work on a truck?
What’s called the “starter” has 2 power connections – a large wire that provides power to the starter motor, and a smaller wire that powers the starter solenoid. When the key is turned to start the solenoid will engage the gear on the starter with the ring gear on the flywheel as well as trigger the starter motor to begin turning.
What do you hear when you turn the key on a starter?
On starters with the solenoid on top (GM, most others) the solenoid grounds through the starter brushes, so when the brushes make bad contact you get the “silent treatment” when you turn the key. The small wire going to the starter solenoid should get 12 volts or so when the key is turned to “start”.
