why is it important to secure the connections of starter to batteries?
does the size of wires matter in this?
im not sure how exactly starting works so im totally clueless here

also, why is it important to disconnect the load first b4 starting/shutting down the generator?

well it kinda makes sense on the starting since it won't reach the rated voltage asap, but the shutting down, why?

The starter on a car is just a powerful electric motor. It takes a very high current from the battery, up to several hundred amps.

Now you know that, you should be able to answer the question yourself.

For the second question, think what would happen if you suddenly removed the power driving the generator, but the load was still connected. What would happen to the output voltage? If it was an AC generator, what would happen to the output frequency?
