Default starter killing battery?!

It looks like the started is killing my battery! is that possible?!

This happend 2 times, car was running just fine, turned it off then went to start it and it cranked a few times but didnt catch. So i left off and went to start it again and it was 100% dead no juice at all. Couldnt figure it out had the battery in the trunk figured the wires got messed up so i hooked a new battery up in the front. Low and behold it happend again.

Try to jump it, i hook the cables up to the battery and no juice, wtf?! So i hook it up to the power wire, and then to the chasis of the car and boom got juice again but not enough to start the car. Tried starting it and where i had it grounded no longer worked, moved the cable to another spot rolled the windows up and stoped trying.

Could the started be giving too much juice to the battery and blowing it out?! Thats the only thing i can think of.

Your starter can not kill your car. You have a grounding issue some where in the car.

you are right, battery is fine. Any ideas on how to trouble shoot the grounding issue?

it seems like the ground is gone, if that makes any sense at all.. Not getting any juice at all even with jumper cables hooked to another car

Check all your grounds above the driverside headlight.

Check ground on the starter as well. Could be the source of your issue.
