your an idiot. what color is the negative wire for everything. BLACK!!!AnswerI think it is the Red one. Red is the color code for the positive terminal (also for your battery tender). Black or green indicates the negative terminal..
Usually black. Look for a negative sign ( - ) which is a just a hyphen.
Normally the black battery cable is negative.
The red terminal on a car battery is the positive terminal which feeds electrical current to various devices. The black terminal is the negative, or ground, terminal which is attached to the car frame.
Black is negative and Red is positive.
The positive side of a car battery is red - look for red plastic cap or the "+" symbol on the plastic next to it. Also the positive post is slightly larger than the negative post.
To jump a battery is exactly the same as you would jump start any other cars in the world. 1. Connect the jumper cable positive clamp (Red color) to the positive post of the dead battery. 2. Connect the jumper cable negative clamp (Black color) to the negative post of the dead battery. 3. Connect the other jumper cable positive clamp (Red color) to the positive post of a good battery. 4. Connect the other jumper cable negative clamp (Black color) to the negative post of a good battery. 5. Start your Mercedes. 6. Reverse the 1-4 steps when the car starts successfully. Note: Step 3, and 4 could be a good strong battery, or a battery on a running car. weijen_hsu@yahoo.com
