2004 ML500 Battery Drain
 

Hey Folks,

I've seem to have a parasitic battery drain -- dead battery after one day of sitting, longer if it's warmer, shorter if it's cold. Battery tests out at 12.5v after long drives, charging system reading 14+v so no problem there. Did a draw test by pulling fuses and found big drop when pulling fuse 8 (states it is transfer case/emergency system).

Any thoughts?

Thanks,
Duane

Disconnect the Tele-Aid control module. It's under the right front seat.

MILS -- Thanks for the suggestion. I'll try and report back on the results.
