Here's the very important thing. Caretaker was not going to blow up the array until after he had died of natural causes because he's a pussy, and he was not going to live with the Ocampa and then blow up the Array remotely because he's vain. So the power bursts (How the Array was feeding the Ocampan city it's reserves) shot from the array to the underground city had been getting faster and faster, then stopped. Followed by the Array letting rip with it's blasters atomizing the power burst collector and sealing off the city just a bit better. In the story we saw Maje Jabin gets curious about all this wierd shit and goes to investigate only to run into Janeway who was already on the case, and they go at it hammer and tong becuase she calls him "uncivilized". Caretaker died of Natural causes about half an hour later, and it was an accident in the fight between the Maquis raider and the Kazon shuttles which cause the automated self destruct to be damaged... A tactic Cullah used later to seize Voyager, and since their entire fleet was stolen off the Trabe this might just be a bog standard manoeuvre for them. If Janeway wasn't there, they had half an hour to get into the Array without Transporters, isolate the caretaker from anything that looked like a control panel and switch off or destroy the self destruct. Doesn't sound impossible if they've been planning assaults on the array for the last 20 years since they annexed Ocampa. So could they have taken the Array?
Just before he died the Caretaker activated the self-destruct sequence for the Array. Voyager/Maquis interference caused it to be damaged. Had they not been there then the Array would have blown up without any problems.
They're pirates, when they think they can get away with it. They wouldn't be able to steal shit, if their victims kept blowing up booty to avoid being raped and eaten. There was half an hour between the Kazon showing up and Caretaker activating the self destruct because he was sure that he was about to die, and even then the program was going to take "minutes" to run through to boom. If they distracted him, "isolated "him from his technology or outright shot the bastard before he tapped his bomb, they were golden, since there was just a couple minutes in the red between Banjoman pushing the button and buying the farm, that if they made enough noise he could have forgotten to push that button. Caretaker could have destroyed the Kazon but he didn't, and he could have killed himself prematurely but he didn't. The old coot wanted every last second of life he could get before someone else, even his own automations had to answer the Kazon question. 30 minutes till Caretaker died. 27 minutes till Caretaker activated the self destruct. 31 minutes till the array blew up. Anything could have happened.
