Put in new battery, now alarm ain't working... Options

[CAMAricer]

Hey guys,

My old battery died so I swapped my battery from the lexus into the celica. But while I was attaching the terminals, the positive side became loose and started to rub against the battery terminal, creating sparks and some smoke. I finally tightened it down (both the + and -) and tried starting the car. Didn't work. I loosed the - end, and the car then had power...but now the alarm doesn't work anymore.

SO...

You think that smoke and sparks may have fried my alarm? I haven't had time to inspect it yet, but I'm hoping it's a blown fuse somewhere...but does anyone else have any idea what else I should check? All other electrical systems seem fine (haven't tried audio yet)....

alarm systems have fuses, replace all of them and you'll be good to go.

a few months ago my starter negative connector came out of the starter, with the plug and terminal, so for me to start the car I had to hold the terminal inside the motor by hand, during this attempt I burnt all the fuses on my alarm system ( more than 8 of different Amp #s ) I got the car back to my friends place and replace the alternator and the next day got under the dash and replace all the fuses, the alarm has been working perfectly fine since then.

correct. There sould be a 10a inline fuse for the + for the alarm.
Replace the fuse and you should be good to go.
