Hi I have a 2001 Z24 Cavalier with 2.4L DOHC 5spd. The car worked fine untill about 1 month ago Driving it along and all guages bounced off zero about 3 times and all dash lights flash on and off then parking brake, abs light and check engine light turn on and car still runs. Turn car off and hear a noise almost like a relay clicking will not stop clicking untill i put my foot on the brake or turn headlights or something on (I figure it is drawing current to another path). tried 2 brand new batteries and won't re-start without jumperpack or booster cables on it, dome light will not come on with new battery in it (full charged) but will come on with jumperpack on it. Alternator charging at 14.83 volts, battery brand new in tonight and won't start by itself (battery holding 13 volts) any help would be great!

It sounds like you may have a bad electrial connection or ground. First make sure there is no corrosion on the battery cable ends at the battery. If that is ok follow the battery cables to wherever they go and make sure those connections are clean and tight.
