brake light & charge light flicker on the dash. anybody know why ? on my 1987 toyota truck 4x4

 

The other day i forgot to strap my battery back in before 4x4ing and it bounced outa the tray and ripped some wires out and it was doing the same thing before i noticed what had gone on. I popped the hood and tryed to recconect as best i could but it was stick flickering. I ended up replacing the terminals and redoing all the wire ends the next day. Check you ground and negative and positive feeds off the battery

 

checked all that & sanded the ground at the wheel well

 

Typically,that means alternator. My battery and charge light would come on and off sparatticly till one day it stayed on longer than expected and the she didn't want to run anymore(battery was discharged.)

My alternator was fried,said the alternator repair shop.
about $84.99 with a core charge at Auto Zone or Orielly's.

 

thats what i was thinking , just replaced two months ago
