Do you have a multi-meter or test light to do some testing?
So you have battery voltage at the battery terminals right?
From there you should check for battery voltage on the main wire to the alternator.
Next you will want to look for voltage at all of the fuses in the under-hood battery box.
Which engine do you have in your ranger?
From there if there still doesn't seem to have voltage then there is a fusible link near the fuse box that will sometimes blow.
