Periodically have issues with gas gauge and light where mileage at will flicker, but now I am thinking I may have a major electrical problem......My blinkers are blinking really fast, my cruise will shut off when the blinkers are turned on, when my lights are on I have no brake lights when brakes applied, my reverse beeper will go off at anytime while I am driving or if someone is to close behind me while its in drive, for example stopped at the red light. Is or has anyone experienced this???? Thanks in advance for your help.

 

Bad ground connection.

 

Thank you, will give this a try
