Why connect positive end of battery with positive end of voltmeter?

The leads of the voltmeter are labeled that way to get a positive readout when you connect the positive lead to the positive terminal of the battery (and negative to negative). Digital Voltmeters will read negative voltage if connected backwards. Voltmeters with a needle, would have the current flowing in such a way that the needle would try to deflect 'below zero' because the needle windings are designed for the current to flow in one direction, to cause positive deflection of the needle.

Your battery died on your 1999 Pontiac transport and you don't know where the negative end to the battery is to jump start it?
Connect positive to positive post (red) on the battery and connect the negative to a place on the engine away from the battery.
How does a wire connect to a bulb?
You take a wire and stick it to the positive end of the batter. Then connect another wire to the negative end of the battery. Connect both wires to the lightbulb.
When you connect the positive to the negative and the negative to the positive does the battery dies?
If you connect the positive and the negative end of a battery directly with a cable, (1) you'll get dangerously high currents, and (2) the battery will quickly run out of energy. The battery itself might also get damaged, due to the high currents.
How do you replace the positive battery cable on a 1997 Buick LeSabre?
Disconnect the cable from the LeSabre battery. Follow the route of the cable and disconnect the other end. Pull the cable out, then fit the new cable in the same direction. Connect the non battery end, then connect to the battery.
How do you wire a second battery in a 1997 Sierra?
Find a position for the battery then connect them together in parallel that is negative to negative positive to positive. That way you will still have 12 volts with larger capacity. Don't connect them in series that is positive to negative because you will end up with 24 Volts.
How do you identify battery terminals without any marking?
Best way would probably be to use a multimeter or voltmeter. Turn the meter on to volts DC and connect the probes to the battery terminals, if the voltage is shown as a negative, then switch the meter's probes around at the battery end so it shows the voltage as a positive reading on the meter. Mark the positive and negative terminals on the battery after this. Some car batteries have the negative terminal as the small post, but on some as the big post.
Does the positive end of a battery go to the positive or negative end of the terminal?
The positive end of a battery goes to the positive end of the terminal. In retro spec, the negative end of a battery goes to the negative end of the terminal.
How can I jump start my automobile battery?
Connect the red cable to the dead battery's positive post and then connect the other end of the red cable to the good battery's postive post. Then connect one end of the black cable to the negative post of the good battery and the other end to a piece of unpainted metal in the engine compartment of the dead battery's car. Then wait 2-3 minutes and try to start the car.
How do you jump start a 1999 Oldsmobile aurora?
1. Connect one end of the positive cable to the "dead" or low battery positive post. 2. Connect the opposite end of the positive cable to the positive post of the battery being used for jump starting. 3. Connect one end of the negative cable to the negative post of the battery being used to jump start. 4. Connect the opposite end of the negative cable to a good ground on the "disabled" vehicle. Start the "good" vehicle and allow the "dead" battery to charge for 3-5 minutes. Start the "disabled" vehicle. If it doesn't start, allow to charge longer, then re-try. After the "disabled" vehcile starts, remove the cables in reverse order of connecting.
How do you jump start a 1992 BMW?
(1) Connect positive cable to positive post of battery that is being jump-started (2) Connect opposite end of positive cable to positive post of battery that is doing the jumping (3) Connect negative end of cable to negative post of battery doing the jumping (4) Connect opposite end of negative cable to GROUND on vehicle being jump-started. Be sure and connect in the order indicated (1-2-3-4). To disconnect cables after jumping, reverse the steps (4-3-2-1). Following the above order of connecting and disconnecting will prevent any sparking or arcing that might fry the ECU or other electronic components.
How do you jump start a vauxhall vivaro van?
To jump start a Vauxhall Vivaro van, start by removing the battery cover. Taking your cables, connect one end of the lead to the positive terminal on the discharged battery, then connect the other end of this lead to the positive terminal on the battery you are jumping from. Take the other lead and connect it to the negative terminal on the discharged battery. Next, use the end of this lead to connect somewhere to ground the current; for example, the engine block or screw connection in the engine suspension on the vehicle providing the jump. When finished, remove the leads in the exact opposite direction you applied them.
How do you hook a car fan to the battery to see if it works?
If you have the fan removed from the car, you can just quickly use jumpers to connect the negative terminal of the fan to the negative terminal of the battery, then connect another jumper to the positive terminal of the fan,and with insulated hands(!) touch the other end to the positive terminal of the battery. If the fan runs, it's fine.
