Have Mercedes Questions? Ask a Mechanic for Answers ASAP
Hi, I’m Ron and I’ll be helping you today.Before we get started though, Please understand that I don't knowyour skill level or tools you have to assist us. Also understand thatI can't see, smell, hear, or touch the vehicle either, so patience isappreciated. JA is a great Q/A site, but it does NOT replace arepair shop.My goal is to make you happy and get a great rating in return formy time. Sometimes I have to give you bad news that I know youdidn’t want to hear, so please don’t shoot the messenger.
Okay, let's start with doing a load test on the battery first. You can still have a bad battery but it has enough life in it to light up the lights etc. If that's good, then please check the cables for tightens and corrosion at both ends. Then check the starter.
