Basic Question-Jumper machine

Well, there is one case where you would want to hook plus to negative and that is if you are wiring the batteries in series. (Or battery and Jumper Machine in series.) This is sometimes needed if it is 40 below and you are trying to start your Diesel truck with 24 volts.
 
Simple - paint the - on the battery to + and the + to -. Is a painted mark on the battery dangerous? If this is all wrong, how do I hook up a charger with a red wire/clamp and black wire/clamp, battery installed and cable attached to starter?

I am saying the same as Post #2. Why is that not disputed?

You must have missed post #5. The trouble with your post is that it is wrong and dangerous. You can put any color wire on your battery but that doesn't mean you can hook up the charger based on the color of the battery cables. red charger/jumper always goes to + on the battery. A spark can blow up the battery and you will be sorry it happened.

How come the battery plus post goes direct to ground through the open braided cable?

Make you a deal. I will hook up my charger the way I want and you do the same. BTW with two cars I still have a garage, no blown up batteries and acid is still all in the batteries.

My post is not just to argue, it is to inform new people to + ground vehicles how to hook up a battery charger so it is done correctly. Any way it is achieved is fine with me.

Had a guy from West Virginia one time ask if I had any “nipping cables” , “jumper cables” in North Carolina speak. I never did get my head around how or why they arrived at nipping cables. That’s been 30 years ago and I still have t figured out the reasoning. Not picking on West Virginia as I know folks who say hainkanade “hand grenade”, plascit “plastic”, southsquatch, “Sasquatch”, old timers, “Alzheimer’s” and on and on.



Fred K, this wasn’t a dig at you as jumper machine makes perfect sense to me.
