there is a wire that gos to the starter that was broke and it go,* to the top of the tranny.i fixed it and now my security light is on.but why would the jumperpack start the car.

Did the car stay running or did it shut off on it'* own? Although I think if it were a security issue it would prevent cranking, not turn it off. But I'm not certain about that.

I would suspect if you have a security light that was probably the wire from the security system you repaired. There are all kinds of threads on here about VATS/security system. Are you getting any crank with the security light on now or no?

I'm thinking this is an intermittent issue which just happened to work when you had the starter pack on. I'm leaning towards grounds or security system, but I'll let some of the experts here chime in before I send you down the wrong path.

Is the starter original? How many miles on the car?. The extra amps from the jump pack could mask an almost toasted starter.

unless you are jumping to the starter the only thing the jumper box does is give the battery extra capacity. if your connections are definitely good then your battery is bad. bad batteries will give you the same voltage reading as a good battery, until you try to start the car then it will go way down and not have the capacity to start the car.

car has 63500 miles. i never replaced the starter

Check those voltages at the starter I mentioned earlier. That will tell us if your starter is even getting the go signal. It'* much easier than removing the damn thing and getting it tested.

If you stick a screwdriver between the posts it should start jumping, but there are much safer ways to test it

i found out what was wrong.the battery was a week old and it was bad.got a new battery problem solved.thats autozone for you,napa this time.thanks everyone for the help.the battery still drains overnight so i just unhook it for now.nothing is running during the night?

Well that'* one down but now you have to figure out what'* causing the parasitic draw overnight. Something is using a lot of power.

I would suspect the battery wasn't actually bad, but the constant full drain and recharge caused it to go bad. Did you check for leaky struts? If there'* something you suspect is draining it, pull the fuse overnight and leave the battery connected. That will lead you down the right path, but might take a few tries.
