Make sure thatit is isolated from other electrical components
Hook up the positive first then the negative.
In a negative ground system, hook the vehicle ground (frame) to the negative of the first battery, positive of that battery to negative of second battery and the positive of the second battery back to vehicle positive. ( starter or starter solenoid) If you are hooking 2 12 volt batteries in series you will have 24 volts.
there is a small box where the battery would be that you hook the positive to and you can just hook the negative to anything that would ground it
DCEN means Direct Current Electrode Negative. Hook the welding cable to the Positive connection (+) on the machine, the ground cable to the Negative connection (-) Electricity travels from Negative pole to Positive pole.
Positive to positive, negative to negative if you are asking about installing one battery in a vehicle.
Depends on what year it's from. On an older truck, hook the positive to a positive battery post, hook the ground to a bolt which goes through the chassis. On a newer truck, which is apt to having chassis-mounted electronics, put the ground to the negative battery terminal.
Positive to positive and negative to negative. The negative will be connect to the engine or chassis. The positive will be connected to the starter.
Not an answerable question Missing type of batteries, and application.
Positive is connected to the positive terminal on the battery and negative is connected to a ground point on the engine away form the battery. Under the Hood, on the passengers side, is a positive terminal with a red plastic cover. Put your ground on a metal part of the engine. No need to pull up the back seat to hook to the battery.
Negative ground systems are basically the same in general as a Positive system. So you should be able to just get a regular battery and just hook your black cables (NEG) to the positive and red cables (POS) to the negative. So basically, just swap the coloring and put a regular battery in it. That's all we've ever done with the old systems that have came into our shop, and we're going back to plain Jane 1932 Plymouths and others like that.
Under the hood on the driver side is a fuse/relay box with a rod sticking out. This is where you hook the positive. Above that on the suspension is a spot to hook the negative but it can hook to basicly anything metal that provides a ground to the car
Connect negative (-) black cable first. Then connect positive (+) cable last. You will see a + and a - next to the posts. Hook up positive first, negative last.
