Then i jump start again and drove for another 4 mils to a parts store. They checked the battery and said it is fine, but the machine says 9.8 - 10 low but good, then we try to start it but it was in starting, so he jump start it agin and i drove about 15 miles, then i shut off, and restart few time, without any problem, but after a little while the alarm go of by itself.
