I have a peculiar problem with my car. The battery drains off within 3 - 4 days. I drive the car for 600 miles to Norwich and the battery is completely charged. It drains off in 3-4 days. I checked for the output from the alternator. In idle condition the output varies from 14.02 - 14.01 Volts, When the RPM is raised the output is greater than 14.10 Volts. The battery is brand new from Lexus. There are no lights on. The music system is working perfectly fine. I do not have a light in the hood of the car casing the engine. The lights are all on manual mode and turned off. The light in the boot is switched off. The light in the glove bocx is switched off. To check if there is a drain I parked the car in the garage and didn't even enable the security alarm. I have done all the checks on my car but unable to find the problem. Also I did remove the main fuse and found my battery tto drain. Have taken to Lexux showroom a couple of time and the technicians are unable to rectify the problem. Pls help. I am sick of jump starting the car.
