85 Toyota pickup 22r battery not staying charged
 

Hello there, so I have had an issue with my truck keeping a charge. I had put a new battery, alternator, and starter in. I had realized lately that it seemed to be having a harder time starting. I didn't drive it for about 3 days and then came back and barely got it to start on its own. The next day it wouldn't start and the charge light on the dash would turn on. Now I get nothing turns on and nothing sparks, or turns over or anything. I've checked fuses and they look good so far. Any suggestions?
Edit: I read on a few forums that it often has to do with buying bad alternators from part stores. Can anyone link me with a good place to buy a stock one?

Without a Multimeter to get some real measurements you have no idea just what is going on.

Could be bad battery terminals

battery cables

The wire from the B terminal on the Alternator to the fuse block

Without some readings you have no idea.

About the best thing for Electrical parts is have the original ones rebuilt local.

Any more I rebuild my own and keep extras on hand to just swap them just in case
