I'm having a little electrical problem and kind of need some help. yesterday i was driving the car and everything was fine until everything just shut off. engine died, lights went out, no voltage, nothing. i check the battery, terminal connections, and everything was fine. i have some voltage now but its weird. sometimes it would read 12v and when i turn the key to the on position it does the normal buzzing sound. when i try to crank it, it just makes a clickick noise and everything shuts off. voltage down to 0. and after that the voltage would slowly go up and reads about 8v sometimes 6v and sometimes 12v. when i try to use any electrical component the voltage drops dramaticly. like the head lights or hazzard or even stepping on the brakes. i tried messing with the raley's ground and stuff but still no luck. any help would be great. thanks.
