3, within 45 seconds turn the key to off ,then back on for 10 min 30 seconds then back on for 10 min 30 seconds.

Hello,

The only way that a wire would melt is if there is too much current going through too small of a wire--say for an amplifier.
Battery cables go:
Negative to engine block
Positive to starter
The battery is used to start the vehicle--the alternator keeps the vehicle running. When the vehicle is off and an accessory is on e.g. the radio you are running on the battery. If the 'new' battery was dead after just 30 minutes then there is another draw on the system. Why did you replace the battery? Is your alternator charging? Did you just put a new stereo in? Have you had these problems before or are they new? something had to have changed to cause these 'new' problems.
Hope this helps.

I would recommend getting a new battery and testing the battery with a multimeter. as for the speedo it may be a stuck needle or a kinked line/ dirty connection. the speedo usually connects to the side of the transmission

That clicking noise is your starter, your battery is dead or severly drained and when you try to start you car, your starter selnoid is trying to turn over, but doesn't have enough juice to get it going, so it's making that clicking noise. If you have a old, dead battery, it is time to replace it, if it's new and only been drained for exmaple leaving headlight on etc... then you can try to jump your camry with a jumper cable through another vehicle. Let it the car run for about 30 min or so to have it charge. You can also take it to autozone, advance auto part and have them charge for free or test it.

well...whenever the battery light comes on in a vehicle its almost always a charging problem,i would suggest replacing the alternator and charging the battery before starting it,alternators were meant to keep a battery charged NOT charge a battery, hope this helps

Synchronization
When
Key buttons operated repeatedly while vehicle out of range and system becomes inoperative. Key batteries replaced.
How - early models
Depress lock or unlock button. Manually lock and unlock driver's door within 30 seconds. System should operate normally after approximately 1 minute. If not, carry out programming procedure.
How - late models
If vehicle locked, manually unlock driver's door using key. Press key unlock button once. Switch ignition ON and OFF. Remove key from ignition switch. Press key lock or unlock button once. System should now operate correctly.

Sounds like you have a bare wire somewhere that is touching metal and grounding out. Probably a starter cable. Try unhooking the battery, check the voltage of the battery, then hook the cable back up, watching for sparks from the cable. After you get it hooked back up, check the voltage again. If you see a small spark, it is normal. If you see a big spark, you have a wire that is touching something it is not supposed to.

If the battery is dead, the ignition keys will not release from the ignition. If there is no signal from the transmission shifter that it's in park since the battery is dead, then the ignition lock will not release the keys.  After charging the battery or jumping the blazer to start it and the key's still will not release, try this. 
There is a "plunger" as part if the ignition. Under the steering wheel there is a small removable cap that you can take off and put a small screw driver up into and press the plunger in and it will release the key. Good luck and hope this helps, Keep me posted be glad to help. 

Sounds as if the alternator is shot.
You can take the battery and alternator in to any parts store NAPA, AutoZone, Murrays, etc. to have it load tested for free.
