your battery will make a big spark or your battery could blow up.
Yes connect the positive first to the positive battery post, and then connect the negative ground to the engine somewhere and not to the battery.
No, always connect the negative last.
If you want to jump start your car, connecting negative to negative and positive to positive is the only way to do it. Connecting negative to positive will result in extensive damages to the electric systems of both cars.
(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.
Connect positive cable of donor battery to battery of car being jumped. Then connect negative cable to negative battery post on the donor car and lastly to a ground point on the car needing the jump start, normally the engine. Do not connect to negative post of battery needing a jump start. Let donor car run for about 5 minutes and then attempt to start. The instant the engine starts reverse the procedure to disconnect the jumper cables.
You connect the negative cable last and connect it to ground rather than to the negative post of the battery because there may be a small spark when you make the connection. Batteries can emit a slight amount of highly explosive hydrogen gas. That spark on the negative post can cause these fumes to ignite and explode. That is why you always connect the negative cable last and always connect it to ground and not to the battery itself as a safety measure.
Positive reinforcement - the giving of a treat when a desired behavior is achieved. Negative reinforcement - turning away from your dog when they are jumping on you or requesting your attention in a negative manner.
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.
Hook up the jumper cables in this order: (1,2,3,4) (1) One end of positive cable to positive post of GOOD battery (2) Opposite end of positive cable to positive post of DEAD/LOW battery of disabled vehicle (3) One end of negative cable to negative post of GOOD battery (4) Opposite end of negative cable to GROUND on disabled vehicle (a good ground is preferred over the negative post, however, the cable can also be hooked to the the battery post). To remove the jumper cables after starting, reverse the order (4,3,2,1)
