Can my car be short circuited?

I took off the positive side of the car battery and I was trying to turn it on but forgot that it was off. Clicking to turn it onIy then realized and replaced it back to the battery. When I did that I noticed that my dash instrument cluster went freaky.
Nothing is reading as it should. Like gas or the temp. Not even my speedometer works. Now noticing not even the lights in the cluster works.

The only reason why I haven't took off the negative is cause it was fastened down and couldn t gotten it moved.

Can anyone tell me what may have happen and how to fix?

Thanks for reading

91 accord coupe quarter glass

I have a 1991 honda accord coupe. I'm replacing the latches in the quarter panel glass because they are leaking. But there are two plastic clips that hold in the front of the glass to the body of the car. Mine disintegrated when I undid the screws. Does anyone know where I can get some replacement clips? I have looked everywhere and can't find them. They seem hard to find. I can post pictures of one I have if need be.

Trading in 2014 Accord Hybrid for 2015 Silverado. Financial advice needed?

I owe $27,500 (23,000 appraisal value) on the accord, and the Silverado is for $43,000. The dealer is willing to do pay off the honda, provided I pay the $43,000 on the silverado. He quoted me a lease payment of $535.00 a month, for 39 months.

I looked up the same vehicle on chevrolet, and the lease payments come up to no more than 360 a month for the same packages. The dealers explanation is "when you re trading in a car with negative equity, the amounts get rolled into the lease." I feel this is baloney, and they are having me pay my negative equity, AND sticker price of the car.

Please advise me.

Added (1). Rebate incentives total $3500, Which means that it I'm left with $1000 negative equity. So with that added to the 43,000, the car is a 44,000 -Selling price, With my $2500 down payment (calculate on chevrolet, on a 44,000 MSRP truck) my monthly payments are at $318 a month. But why the dealer is asking for $535 is beyond me!

Radiator fan only turns on when my car is off?

I'm going to a mechanic tomorrow, but I'd like to have an idea of what the problem is before I go in, so they don't overcharge me for repairs I don't really need.
I have a 1992 honda accord. It has a lot of problems, but has been, for the most part, drivable. I've had problems with the fan in the past; it doesn't turn on when my a/c is on, so my car will overheat. I pretty much just ignored that though (would rather save money for a new car than spend it on a repair that isn't 100% necessary) so I just don't use the a/c. But today, I noticed my car overheating while driving. A/c was not on. So I pulled over, checked the antifreeze, etc. After playing around with it for a bit, I noticed that the radiator fan only turns on once the car is off. So the fan itself is still functional, and when the car is off, it recognizes that it's too hot. But when the car is on, the fan will not turn on, no matter how hot it gets. What do you think could be the problem?

Engine build ideas for my 97 Honda Accord? I know 300+ horses is a bit of a longshot but?

I have all the mods that I need to support a turbo. I know the stock f22b2 block can handle up to 10psi and around 300 hp on stock internals. My F22b2 engine I have been working on was rebuilt with forged internal components for future boosting. My question is should I use my modded f22b2 head or go for a vtec and DOHC like the H22/H23?

Mods on my current F22b2 setup:

Block:
Forged pistons and steel rods

Head:
Performance valves and springs,
H23a intake manifold, 550cc injectors and aem fuel rail

All my pre-boost upgrades are for the F22b2 engine build. So if I swapped to a H series engine I would have to buy those supporting mods again to accommodate for a turbo later on. Maybe a G22 build? A modded F22B2 block with a F23 head on it? This is my daily driver and need reliability like I have with the current f22b2 that is in my accord (305k miles strong) What do you think would be the best combination for reliability and will hold up alot of boost later?

I would like to reach atleast 300 horses after adding turbo and a tune. If that can't be done with my current f22b2 build let me know what I need to do to reach my goal.

Single Vehicle Collision, police notified but did not make a claim. Will my rates go up?

I'm 22 years old, been driving since I was 16. Full G License since June 2011. February 2015 I was cut off by an SUV, hit the brakes, hit a patch of black ice, and went into a snowbank. Wasn't hurt, but my bumper was totaled. I reported it to Police Collision Center (stupid decision, I know), had info of the guy that cut me off and a witness, but no go, police told me I was at fault. Never had any fines or tickets from that accident. I paid for the bumper out of my own pocket since my deductible was $1000 and the bumper was $850. Didn't go through insurance.

Because I reported it to the Collision Reporting centre, would my insurance company know and increase my rate at my next renewal? I'm currently with Economical and have been for the past 3 years. I was with Aviva before.

Also, unrelated, but is BelairDirect online quote system accurate? I got a quote for $3,200/year with an accident on my record (2006 Honda Accord EX V6), but when I did it on insurancehotline, my cheapest quote was $5,500/year, which is insane. But I didn't see Belairdirect on the list of insurance companies they use, so I don't know.

Added (1). Forgot to add, I live in Southern Ontario if that helps any.

Is a 01 Honda Accord with 241k KM on it a good car?

There's some rust on it but the ad says its mechanically sound and its for $2000 apparently already reduced. Will b my 2nd car (old one is a 99 Grand AM) Or should I buy a 00 Neon Sedan with 240xxx km and i know nothing else about it (will find out more info on both, just wondering which is more reliable)
