Hi. I replaced my battery almost two months ago on my 09' 328i. About two weeks after that i started to have electrical issues. It first started when I went over a speed bump, then any bumps, and eventually would happen randomly. The car will shut off / lose power, turn back on (within a second or less), rev to 3/5 rpm, & mainly the ABS sign will come on. This is all happening simultaneously, but will go back to normal within 1/2 seconds.

I did reset my battery about a week after replacement. My current suspicion is that it has to do with the wiring to the alternator, or just in general the alternator. I haven't found any dialog on this specific problem & am slightly new to DIY with my e90, so any help is extremely appreciated.

Would like to know if anyone else has ran into this issue and/or anyone can help with a diagnosis/solution.

Thank you!

Are you sure you put pushed the battery terminals all the way down on the lugs before tightening ? the first time I had the battery out I just placed the terminals on the lugs and tightened but this did not put and actual mechanical grip from the terminal to the lugs. End of the cable must be pushed down
while tightening.

This did the trick! Thank you.

When I was installing my stereo I missed this the first time thought
I had ruined the car till I pushed the connection to the lug all the way down while tightening.
