No! You should never cross connect two batteries or a battery to charger in this way. At minimum the battery could be damaged. At worst it could cause an explosion.
your battery will make a big spark or your battery could blow up.
if you didnt un-connect the battery you could have fried it.
There are many ways to connect (6) 6V batteries. For a series connection (adds up to 36V) the most convenient method is alligator clips.WARNING!!! DO NOT EVER connect the first battery to the last battery. They may blow up, and this could hurt you.

It could be compared to a house's framing because it helps support the structure of the house.
You can do anything, but is it safe or proper. No The 24 V will eventually overcharge the battery after a while and start damaging it. (A flammable gas is produces and the battery could explode.)
You could Install a battery cut-off switch or Connect an amp meter to determine parasytic load on battery or Connect a test lamp in series with battery if there is an excessive drain the light will illuminate-then pull each fuse one at a time until the light goes out and that will indicate which circuit is draining battery and repair from there or could be a bad voltage regulator
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
Only the computer can tell what made your check engine light come on. It could be your battery. If your battery is bad, replace it and see if that solves the problem. If it does not, then you will have to connect your car to the computer and find out why the check engine light came on.

I run a Breakdown Recovery business and have seen this before. Usually it happens when the battery has zero (I mean ZERO) charge and you are merely charging the battery using jump leads. An easier way to start it is to connect the positive cable (red) as usual but connect the earth to the engine direct. This should help unless the problem is not the battery.
