bad ground wire/s??
 

i need to change my ground wires in the engine just wondering how many there are. i know of 2 but just asking if anybody knows more. thnx 4 the help

Most models just have two stock. One from battery (-) to the frame and then to the transmission. The other from the valve cover to the radiator support. You can always add more if you want to. Why do you think you need to change them?

guy at advanced did a drain test and came back 0.13. dont really know what that means but he said it shld read 1.?? plus the cars got 200k and they're original. im slowly replacing everything.

I don't know what that "drain test" means either. Realize that the guys at Advance typically don't know a lot about cars. You should check that the connections on the ground wires are clean and tight.
