Mercedes Repair Questions? Ask a Mechanic for Answers ASAP
Hello, my name is Bobby. Thank you for the question. Can you tell me if there is any message on the dash when you try starting it? Did you happen to accidentally cross the jumper cables when performing this task? Did your vehicle run fine after the jump?
Thanks Kerry. The battery cables were not accidentally crossed at any point were they?
If they were then that can cause some serious problems. Hopefully it did not short out any of the modules. The most common failure is the fuses that are inside of the box located right near the battery. Those should be tested first before going any further.
It is the prefuse box that needs to be tested. The attached picture indicates the one under the hood.
