Diode (rectifier) is cheapest thing to replace.  Also fairly easy to test.

Check your wiring for bad grounds or loose contacts on the battery

Do a voltage test at the alt, should be 13.8-14.2 volts, if nothing there, there should be a plug that goes into the alt. With the key on there should be power in both wires, you have to pull the plug out of the alt, if this tests out. Power to alt.in the plug, then it's the alt. If no power in one or the other 1 is to turn the regulator on, the other is the sence wire, that might be a fuse or a fused line, once you have power in both wires in the plug, push it back in and try another test at the power stud on the back of the alt again. If nothing again, test positive "hot" wire to the back of alt, if you have power at all the places, have the alt tested by a rebuilder, not a auto store. They are to dump to hook it up to the tester and use the correct plugs for that alt. Good luck!!!
