Electrical problem
1997 Mitsubishi Eclipse 4 cyl Two Wheel Drive Manual

Put new battery in car just last week but it keeps going dead after in less than 24 hours. Car radio died 2 weeks ago but CD player works fine. After start up I hear a whirring sound when I hit the accelerator. I teventually goes away.

Car starts immediately with a jump. Shoudl I disconnect battery untill solution is found. I am afraid I will damage battery by letting it drain down to often

thanks, first time user!
