On a vehicle the red is positive (+) and the black is negative (-). If they are not color coded the cable connected to the starter is positive and the cable connected to the engine or chassis is negative.

the battery will have a - mark on it which means neg., and the cable that is bolted to the engine block is the neg. cable, the pos. cable will go to the starter.

Electrical isn't your strong point, is it. If you take the neg. cable off the battery then you will not measure any voltage between the neg. cable and the pos battery because there is no complete circuit back to the neg side of the battery. I would start by making sure that the battery connections are clean and secure, as well as the main connection at the alternator. Check that there is no corrosion on any of the terminals. Use some sandpaper if you need to clean them up, on the terminals and the cable connectors.

Start the car and while it is running, disconnect the positive cable from the battery. If the car stalls, the alternator is bad.

yes, 1 neg. + 1 pos. = neg. 2 neg. = pos.

No. An AB neg can receive blood from any blood group with a negative Rh (A neg, B neg, AB neg, O neg).

Depends on the car. An E30 BMW neg battery cable is about 6 inches. The neg battery cable on a Chevy small block about 2 feet.

neg cable bolted to the body of car.

There's no general rule. The result could be positive and it could also be negative. It depends on how big both numbers are. (neg 5) minus (neg 7) = pos 2 (neg 5) minus (neg 3) = neg 2

check make sure the neg. cable is tight, check cable for corrision in cable by flexing cable if it hard u need a cable, also check for cable tightness to connector that connects to battery. Did you hook the pos. to neg. and neg. to pos?

Yes. Two Rh positive parents can produce an Rh positive OR Rh negative baby. Parents where one is Rh pos and one is Rh neg can also produce an Rh pos or neg baby. Only two Rh neg parents will always product an Rh neg baby.

It depends if you are A pos or A neg. If you are A pos, you can receive A pos, A neg, O pos, and O neg. If you are A neg, you can receive A neg, or O neg. The reason for this is that if you are A neg and receive Rh positive blood, it is possible you may develop an Anti-D antibody (Rh antibody)which would cause you to have a reaction to further transfusion of Rh positive units.

Battery is in trunk, but in front under hood there is a fuse box next to it there is a cover with a "+" sign. lift and connect positive cable there. connect neg cable to frame(I use the strut bolt).

Normally Positive (+) is RED and Negative (-) is Black.

Yes, the possibilities are A pos or neg and O pos or neg, see the related link.

Neg=Ground, with nowhere for the charge to escape, then it will not complete the circuit

Yes can be either pos. or neg.

if the atom has more protons then electrons it is positive and vis versa


No. Rh negative is a recessive gene. If there was a positive gene, it would be dominant and one of the parents would HAVE to have it.

I think its either O neg, AB neg or Rhesus D Positive.

the negatibe cable will be black. the positive cable will be red the negative cable will bolt to the vehicle frame or body the positive cable will bolt to a solenoid or starter motor also usually the cables will only fit one battery terminal. battery terminals are different sizes

The answer is the normal quotient except negative. Pos X neg = neg

Red is positive. If they are both black then the cable that is connected to ground is negative and the other cable is positive.
