Just replaced my bad alternator battery still good what happens is the car starts but it struggles to and if I have the car off and if I leave a door open after a few minutes it wont turn over it clicks and popping noises come from speakers after a minute or less then it will start maybe its the battery? How about the starter what are symptoms of the starter motor going?

Re: 03 sls starting issues

If the battery is more than 5 years old, that's a prime suspect. Others are constant power drains - stereo amp stuck on, aftermarket stereo work with improper wiring, security issues, battery cable connections.

Have you checked the battery (under the rear seat) for cleanliness and clean connections, especially the floor pan ground stud ? If the car has heated seats the rear seat electrical connector is on the passenger side - careful - disconnect it.

I'll make it unanimous. Sounds like a bad battery to me as well.

First thing check and clean the battery terminals! Bad battery or dirty cables will kill your new alternator.
