Ok about 3 months ago I had a problem with my car not starting. Id turn it on accessory and everything would come on, id go to start the car and it would click and all power would shut off. if i wiggled the battery ground wire it would start eventually, sometimes taking about 5 times of wiggling, trying to start it, power shutting off, wiggling again, etc. so i cut open the ground wire and it was corroded thru, makes sense as when I gave it a heavy load like starting the carm it didnt have enough conductable metal to ground all the power. But now I have a 2 month olf ground wire that appears to not have any corrosion and it just started doing this again, like i said I wiggle it and all the accesories come back on and eventually the car will start. any ideas what it can be besides the ground wire. I highly doubt a 2 month old wire is corroded thru already.

 

change your battery.. or pour coke on the whiteish looking stuff thats building up..then water it down...i suggest getting the red green thing for the battery its like anti corrosion stuff just go to pepboys and ask for the rings fo rthe battery

 

Did you change your positive wires as well? I'd recommend OEM battery cables, $$$ but it's worth it.

Get your batteries tested as well...they do it for free around here.

 

oh yea i replaced the battery at the same time so its only 3 months old as well. Ill look at the positive wire tomorrow.

 

Someone already mentioned corrosion at the battery posts. But also check for corrosion at the other ends of each cable. Clean up the metal where each cable attaches. Make sure all the connections are solid. Disconnect the cables and check the surfaces that make the contact. That's more important than the outer surfaces.

You understand about the corroded ground cable (not enough conducting material left), but the exact same thing applies to the (+) cable, and each place where the cable itself is crimped into its end connectors, & where it's bolted down at the other end. Corrosion doesn't conduct electricity very well, wherever it's located.
