2007 ford taurus, was driving along and check breaking system came on then about a min later, lost all dash lights....now car wont start and i have lots of battery power when i turn key off i hear a bunch of clicking noises from behind the wheel in the dash...was no sign of this happening, what could it be...never owned a ford before
there are many different circuits in vehicles now days. It is very possible that you may have full voltage at some circuits and not the correct voltage at others. A relay clicking may be caused by not enough voltage to hold the relay down or that the module that controls the relay may not have enough voltage to know what it is doing.
you should go through and check for a voltage loss somewhere in the system. A switch, a connection, a bad fuse panel. there are all sorts of electrical things you would need to check. I would start at the wiring that goes to you ignition switch. Check to see if you have the correct voltage coming from the battery source for voltage to start and run your car.
