So i got a used car and have been driving it for about a year, since i ve had it i noticed that there was some elctrical problem (probably coming from where the car was hit on the front right side) the left blinker has always blinked faster and sometimes i here a weird clicking sound when im driving that goes away and sounds like the blinker) Now today i got in it and the tcs light, battery light and parking break light were all on and the radio lights were flickering, after driving it all day with no problems i went back to drive it at night and when i put the keys in it seemed like the battery was really low, and the left blinker was going a million miles an hour! So i started driving at night and then electrical stuff just started shutting off periodically, first the radio, then the odometer and rpm meter, then the dash lights, then all the lights, then the car julted to a stop in the middle of the road. I pushed a ways and tried putting my key in 30 mins later and it seemed to have all its power back but wouldn't turn over, just clicking. I jumped it and it started up, then began to loose power faster than before till it died again. Is it electrical or the alternator? any insights appreciated, thank you

 

Unless your battery is new that is most likely the problem. Most batteries are good for about 3 years then they will cause some issues.
When your blinker light is going real fast that is most likely a light that has gone bad.
Check all the bulbs and replace the one that is out. I usually get them at an Auto Parts store like NAPA the box stores that have the bulbs sometimes do last very long.
