1. Glow plug relay might have intermittent fault, turns on randomly and drains battery.
2. Alternator harness at alternator has bad connection, won't pass enough current to charge the battery. 3. Battery cables are bad / corroded under the insulation, won't pass enough current to charge the battery. 4. Some other component like the radio or the antenna stays energized when ignition is off and drains the battery. Add Opera dome light, glove box light to possible culprits. -- Max Dillon Charleston SC On January 22, 2019 3:55:40 PM EST, Patrick Atuonah via Mercedes <mercedes@okiebenz.com> wrote: >Hi Listers, > >Thank you for your valuable advice regarding my previous post about my >car >mentioned above. > >Got response from the dealership tech. > >New ignition switch installed and it didn't see the charging issue. >Whew! >Saved me $700. > >I will be picking up my car Tomorrow(Wednesday)and take it to another >shop >owned by my friend. > >Now what I know: >Alternator is brand new and good >Battery is brand new and should be good >Ignition switch is not the issue (original switch put back) >No $0.00 charge for diagnosis > >Can any of you give me a list of what to check to figure out why no >battery >charging.
