Battery / Engine start issue
I've dead battery then replaced a new AGM battery. First week run and start like dream but second week I almost need to jump start my Z4MR every morning. I'd charged the battery over night but still need the jump start.
Do I need new starter? (But when I jump start the car start pretty good) or something else like something else. Seriously I've no idea now. Anyone has similar experience here??? How can I fix it??? Thanks ALL~~~ |

need to run electrical system diagnostics.
but it sounds like its not charging, which could be the alternator or something as simple as a bad connection.

I found it if I unplug the amplifier the car start perfectly every morning and Now I replaced another amplifier after 2 weeks this problem back again.
Would that be the radio unit or something else draining the power away??? Anyone got similar issue with that??? Stereo units drain the power of battery |
