Hi,
I am just joined this site, and need your help.
I have a 2008 MKX.
Issue is Battery Dies within 48 hrs of not using car.
Troubleshooting
Replaced battery.
Still notice Voltage drop from ~ 12.6v to 12.15V over night.
pulled the following Fuses as seen a voltage drop across them when car was off for over 20 minuts.
7&8 - Low beam
39 - Radio Always hot 20a(according to haynes manual)
2nd day,
Also pulled many 20 to 30amp Fuses under the hood.
Fuses 59 to 65. 16-18, disconnected Alternator.
overnight - Voltage drop from ~ 12.6+ to 12.18v
4th day -
Replaced Delayed Accessory Relay(48). and reinstalled all fuses. ~ same voltage drop overnight. 12.6 to 12.15v.
I Have not unplugged the computer fuses yet. Did not want to corrupt the computer.
Have owned car for 6 months. Front seat Heat/Cool did not work on either passenger or driver seats, when purchased.
recently installed Trailer hitch and lights. Noticed Battery Drain 2 weeks later. Have disconnected light kit.
Car did not typically sit for more that 1 day most months. So not sure this addition affected anything.
Also notice that the Radio LED(side controls) will light up every 15-30 seconds when car is in sleep mode(or should be in sleep mode). Only way to stop this is to remove the 20 amp radio fuse.
