I watched BTTF1 yesterday and I have an idea for the BTTF1 Del. of 0.2d, if it can be done.

In the movie it seems that after Doc upgrades the Delorean in 2015, the time circuits and the time travel preparation things (sparks and stuff when the car goes above 80MPH) run off Mr. Fusion., but before that, when the Delorean is still plutonium powered, it looks like that these things run off the car battery to conserve the power of the inserted plutonium pellet for the time jump at 88MPH.
Three examples of this can be seen in BTTF1:
1. Marty arrives in 1955, escapes from the farm, drives over to the Lyon Estates billboard, leaves the car idling, when he returns to the car, it goes dead, because the battery gets very tired from the strain of the time travel preparation when Marty is escaping from the Lybians, and when he arrives in 1955, he leaves the time circuits on the whole time until they go dead too.

2. On NOV 12, Marty drives over to the "start line" at the Bluebird Motel, he again leaves the car idling, he leaves the time circuits and the headlights on too, he puts the lightning rod onto the back of the car, he gets in, waits, waits, rewrites destination time to 10 minutes earlier, waits, car goes dead, because the alternator generating power at the motor's idling power couldn't keep up the strain of the time circuits and the headlights on full power.

3. Marty accelerates up to 88MPH, he's not at the lightning wire yet, time preperation things shoot sparks, drain extra power, lightning strikes BOOM! 1985, Marty gets out of the car to see if he's at home now, again leaving the car idling with time circuits and headlight on, and the car goes dead again.

So understanding these three things, here's what I thought of:
If you just arrive from time travel, and stay in one place with the BTTF1 Delorean with the Time Circuits on for 1 minute, the car and the time circuits go dead and you have to wait 10 minutes until you can turn them on again.

If you just leave the time circuits on, without time traveling before, with the car in one place, idling for 5 minutes, they go dead again, but this time it should only take 5 minutes to "recharge".

What do you thing about this idea?

Yeah, i already suggested that feature. Marty didn't know the existence of a "voltage regulator" like this
on the bttf1 delorean.The answer is no. Too buttons to upload that feature in the mod.

sounds good to me

Aug 31 2007, 1:43pm Anchor

It's still not out of the picture quite yet though.

Aug 31 2007, 2:35pm Anchor

don't forget einstein's trip. The car came back completely dead. You would have expected to hear the engine, but all you heard was brakes.

Aug 31 2007, 2:58pm Anchor

That's cause it freezed. The flux dispersal apparantly takes too much heat, plus stainless steel freezes easily, that's why the engine just died. Happens a lot to Russian cars.

Aug 31 2007, 3:08pm Anchor

Yes, that explains why the car froze to death in 1955 and after coming back from then. (sarcastic)

The engine goes dead when Marty arrives in 1955 instantly, I just watched that scene again to confirm it, and the moment he appears in 1955, the engine goes silent, but the electrical systems still work. By the time Peabody returns the second time with the shotgun, the engine thaws out, Marty starts it again, drives to the billboard, then it's too much for the battery with the time circuits on and this time it the car goes dead because the battery drain.

Maybe this could be implemented this way:
If you arrive somewhere with the BTTF1 Delorean, the engine goes dead, and you would have to wait a while before you can start it again, and after that, if you leave the car idling for 1 minute both the engine and the time circuits go dead, and you have to wait 10 minutes to start them again.
And if you don't time travel or spend some longer time without time travelling, they would only go dead after 5 minutes of idling with the t. circuits on, and this time it would only take 5 minutes to "recharge".

The first time was the most extreme one, that's why the car has frozen without any chances. But other times were more like easier, that's like going to the dentist. No, wait, that's like riding a bike, first time you'll feel a little pain, but then you just forget about it. That's why I think Marty made it from the Peabody farm. Maybe you're right, maybe when he made it back to the present, the electric bolt overcharged it a little, why he could drive the car out of the cinema. But remember, it wasn't ten minutes before Marty could start the engine for the lybian chase. Why did doc have to tow it back to his lab?

Ok, so the car comes back dead for bttf1. However, I do not agree with you about the idling thing. I'll read the pamphlet and try to understand it first.

Edited by: Delorean88us

I modified my post. Read it again please.

Aug 31 2007, 3:26pm Anchor

If you don't agree about the "dead for 10 minutes" well, I too admit that it was a bit extreme, but would it be acceptable with a time less than 10 minutes?

Aug 31 2007, 3:25pm Anchor

Maybe they Marty never tried to turn on the car, figuring something was wrong with the starter and he didn't attempt to try again until at the lab.

Aug 31 2007, 3:27pm Anchor

Also makes me wonder if maybe the reentry was enough to cause the engine to die. Remember, it did also die before Marty sped off towards the clocktower, and I hardly call hitting his head against a steering wheel electricity to start the car.

Aug 31 2007, 3:34pm Anchor

Maybe the hit on the steering wheel, caused something in the circuitry to apply the remaining power, even though there was seemingly no power left, like when the batteries die in the remote control, you flip the batteries, and it runs for a while like that even if you don't switch the places of the batteries.

Aug 31 2007, 3:37pm Anchor

well there were three buttons on the steering whell maybe they did something

Aug 31 2007, 3:39pm Anchor

Well, here's my theory based on the pamphlet, the reactor supplies the power to the electrical systems, and I'm guessing that Doc took out the battery and replaced it with the reactor, which serves as a power source (takes in plutonium) and battery. When the delorean goes back in time, the reactor sends all its power to the Flux Capacitor to guarantee that it gets 1.21 gigawatts and nothing less, while the capacitor itself makes sure it gets 1.21 gigawatts and nothing more. As a result, there is no more power int he reactor, and dead battery = dead engine. Now, almost immediately after the reentry, the excess power does go back into the reactor, but at a slow rate. As a result, when Marty leaves Peabody's farm, while there was power in the reactor, it was still too low and didn't bring Marty very far. However, during the one week stay, all the power left in the flux capacitor finally made it to the reactor and allowed Marty to go back to 1985. I reckon that the delorean dying at the start line was just one of the mechanical problems of the delorean, as all it needed was Marty hitting his head to turn it on. So, it needs time to get some charge back. How could the reactor get back all of it's charge? The answer comes within the voltage regulator, which has 3 buttons for automatic and manual to/from reactor power transfer. Now this baby lets electricity flow back to the reactor almost instantaneously, allowing normal operations if the button is pressed. Well, thats my theory. My brain hurts now.

Then Marty would have an extremely bad headache from hitting his head on plastic buttons.

Aug 31 2007, 3:41pm Anchor

well if you remember Deloreans hav always had starter problems so maybe it was to show that cintematics happen with simple problems

Aug 31 2007, 3:42pm Anchor

oops double post see the post that is below yours

Oh shut up Ronnyboy. You're going to see a wave of insults if you keep this up.

Edited by: Delorean88us

Aug 31 2007, 3:43pm Anchor

I like you theory, Delorean88 if this could be applied in the mod, it would make the BTTF1 Delorean very realistic, because that Delorean isn't as "user-friendly" as the other ones.

Aug 31 2007, 3:44pm Anchor

Yeah, I'll think I will implement that. Well, we'll wait until someone questions the theory besides Ronnyboy here, who I doubt has a total understanding of it.

Aug 31 2007, 3:44pm Anchor

ok ok I'll stop bashing a good car and common car facts

Aug 31 2007, 3:44pm Anchor

and then we all wonder why the delorean never had any problems after it got mr. fusion....and I really doubt that they had any good repair services in 2015 for internal combustion cars, as most of the future cars certainly don't sound like one, and if the fuel stationis any indication, they are rare in 2015.
