Have Mercedes Questions? Ask a Mechanic for Answers ASAP
Hi, it's pretty risky running with a positive jumper installed. If you insulate the jumper so that there is no possible way that it can short out to the chassis I would be comfortable. I would only do this to get the car to the dealership. I would not drive around town with the jumper installed.
Let me know if you need anything else. Please remember to rate my service in order for the website to credit me for taking your question.
You could purchase a heavy gauge piece of wire and make the connections but a jumper cable will work fine as long as you protect it from shorting. If you disconnect the negative cable it is safe to work on the electrical system.
I'm not following you. Do you want the amperage rating of the prefuse? There are 2 - 100 amp and 1 - 40 amp circuits.
The part number is ***** 540 08 50. It retails for $65 at the Mercedes dealer. You can purchase one here.
Hi, sorry for the wait I had to leave last night. A 4 gauge is fine. The prefuse is for the ESP module and the suction fan and the engine compartment fuse box.
Let me know if you need anything else.
