POLCATT

I have power to everything-except when I hit the start button nothing happens. All goes dead. I charged the battery-changed the battery-bought a new battery-had all the batteries tested. Checked all the fuses-changed ALL the fuses. Still nothing!!!

Car is turning into a lawn statue. (2008)

Checked neutral safety switch as well...HELP

Might check the connections at the starter. Known problem area both hot and ground connections.

Starter checked...both ground and hot check out good. Keep the suggestions coming...still searching.

Is new battery fully charged?

POLCATT

Yes---but taking it back and getting another one.

I just noticed the battery on its own will not power the car-I need to put the battery charger on boost in order for it to charge anything.

Going into town to replace the new battery I just bought. When I test the battery it shows charge-but when I turn the key it goes to zero (0).

Make sure the new battery is fully charged before leaving the store.

AORoads

Right. Have the store check it just as they would if you carried in an old one for testing.

How did you check them? A simple continuity test won't tell you anything. Although I would need some expert advice before attempting this on a complex modern vehicle filled with electronics, in an earlier life I would take a jumper cable, hook one end to the negative battery terminal (remove the ground cable) and the other to a good ground. If it cranks over then you have a weak connection in your ground cable/terminals. If it doesn't crank, wiggle both ends and try again.

To check the positive cable/terminals, I would also just short the solenoid terminals with a screwdriver, and if the engine cranked over then there is a problem with the positive cable and/or connections. Ha, I don't think I'd try this on my C6.

But the safe way (on a modern vehicle) to rule out the far ends of BOTH battery cables as being the problem is to remove them, clean everything up with a wire brush, Scotch-Brite, etc. and re-tighten.

I took the starter off and did the old fashion jumpers utilizing a vise- starter kicked over. I also tested the positive and negative cable for continuity-to ensure there was no short. All tested good. I traded my new battery for a new battery-changed all the fuses (after checking them). Hooked everything back up---Car started right up. I have turned it on and off several times-all is working as it should. The cause of the problem is still unknown-all contacts have NOW been thoroughly cleaned-maybe that was it. Maybe not---GREMLINS gotta love them

I was gonna say, did you run a trouble shoot with a scanner, that oughta tell you the code/issue really quick.

Bruze

The odds of it being a bad connection are much higher than the odds of getting a (2?) brand-new batteries that were bad.

FWIW, continuity test on the cable: What you needed to know was: Is full current available between the battery posts and the terminals that they ultimately connect to? It might not be (if the terminals are dirty) even though the cable itself might be fine.

if the battery wouldn't power the car,it was ''JUNK'',,get a battery tender,if you don't drive it much,,''c-tek'' makes a great one,and make sure your alternater is charging the battery at 13.9-14.2 volts when idling,and charge the new battery over-night to fully charge it before using it
