Tip & How-To about Car Audio & Video

My lights dim in my car, is this bad and what can I do to stop this from happening?

Lights dimming in your car is an indicator of a low voltage problem. This can be caused many problems. You might want to have your system checked out to make sure it is running smoothly. Low voltage can be a serious problem. Low voltage will cause an amplifier to put out a DC voltage rather that AC, which can damage your speakers. Low voltage can also cause damage to an amplifier by not providing enough power to the amp to run properly. You can add batteries and/or capacitors to the system to help with voltage problems. Please consult with a professional to make sure you get what you need for your specific setup.

Check all grounds ie motor to body ground strap connections for corossion, battery to motor ground, battery to body ground. You have to check under bolt to see if there is coeossion. Bad grounding can cause all sorts of electrical problems

battery and brake lights flicker and headlights dim


Sounds like a low voltage problem, alternator not charging properly. When you press the gass the motor takes more juice from your battery to fire the spark plugs have you had your charging system tested (most auto parts places do it for free)? Either that or a loose wire causing the short. Check all grounds under the hood and make sure they all have a good contact

highbeam lights very dim


Check the ground wire from them. It is what causes them to be dim like this. It likely has a bad connection.

Did you have the alternator check? Low voltage will cause light dimming.
