Hard to say. It may cause no damage at all and then again it might cause serious problems.
No battery, discharged battery, poor electrical connection, damage.
There is the possibility the battery could blowup. You can damage the complete electrical system.
No, and it may have caused major damage to the elctrical system.No, and it may have caused major damage to the elctrical system.
Cause the battery to explode or damage the electrical system in the car.
Absolutely not. You will also damage the electrical system.
Boom
Shower doors are known to spontaneously explode and this is caused by one of three things; impact, edge damage or inclusions.
Not if you jump it from the battery or electrical system of another car.
Effects of Incorrect Polarity When Connecting an Auto BatteryThis will usually result in severe damage to all electronic components in the vehicle's electrical system, and could result in melting the insulation on much of the wiring, and even melting of some of the wires.In a "worst case" scenario, it could even cause an electrical system fire which could result in burning up the entire vehicle.And, although I've never seen it, I have heard "stories" that connecting an auto battery "backwards" resulted in the battery exploding.
You change polarity which can very possibly damage all electrical components.
MCBs protects electrical circuits against the damage caused due to overload or short circuits
The battery is used when the car is running to stabilize the voltage and store energy from the alternator. It is not recommended to run the car with no battery, as this can damage the alternator and the car's electrical system.A dead battery (if you have one) can usually suffice to run the car for a short time, however it may also damage the alternator.
