Replacing a lower amp generator with a higher one won't hurt. The 130 amp generator doesn't put out 130 amps, it is just capable of generating more amps if called on to do so by the system. For example, if your explorer only uses 10 amps, then the 130 amp generator will only put out 10 amps.
The formula you are looking for is W = I x E. I = W/E. A = W/V.
You did not say weather the light goes out and if the generator charges. At low idle a generator will not put out it full amps.

it depends on the voltage source being offered by the generator. watts / volts = amps If the generator is providing 120V, it is capable of pushing 125 Amps. If the generator is providing 240V, it is capable of pushing 62.5 Amps.

Check the number of amps that your circuit can handle. You should not put devices with more than that many amps (total) on that circuit. Most houses are 15 amps and bathrooms 20 amps.
You should not load a 125 amp panel any more than 100 amps.
A few small things. Watts = Amps x Volts. Amps = 800/120 = 6.66 amps. Check the amperage on what you want to plug into the generator. If it is over 6 amps the generator will not handle the load.
Yes it should, check the output amps/watts against the amps/watts your polisher uses. presto, if they are close just start the polisher and watch the load you put upon it. If you work it too hard you will pop the circuit breaker and need to reset.
It depends on the alternator. Some only put out around 40 amps while others that supply power windows and heated seats may put out around 120 amps or greater. Some heavy equipment and buses put out around 300 amps. Best way to find out is look up the specs in your owners manual or call your dealer with the make and model of your car.
It depends on how much you are willing to pay. For an economy generator, the cheapest generator will put out 2500 watts, while the most expensive generator will put out double that amount.
