Probably your battery cable or cables are loose on one end or the other.
An elf under the hood who's disconnecting and re-connecting the battery terminals!
Since the dashboard lights are flickering, it sounds like a possible wiring problem. Check all of the main wires from the battery to start with, then check the fuse box for any loose wiring.
it is caused by the alternator voltage regulator switching on and off to charge the battery, this problem is encountered on many makes of car, you may not of noticed it before prior to exchanging the battery.
The alternator may be on it's way out.
Yea its an electric or body comtrole module .about 400.00to repair at dealer. Will cause lights to flicker off & on and sometimes horn will chirp also while driving
Have your alternator tested. They will sometimes do that when they are putting out low outputs at low rpm.
Yes
Possible alternator problem
Because power from the battery, which was going to the lights, is being utilised to turn the starter motor. You should really start the car before you turn on your lights to avoid putting unnecessary strain on the battery
It probably isn't a relay- what you will most probably have is bad battery connections, a bad ground, or bad connections/w fusible link down on the starter.
Might be a weak battery
Sometimes the ground strap to the body of the car can come loose. This will cause things to flicker. Ground from the battery needs to be connected to the engine block, the frame, and the body to keep things working properly.
