Bad Alternator?

If the battery is that old, replace it, end of story

If "something" is making noise "up there" you should be able to spin the water pump, alternator, etc by hand to see. Excessive play in the water pump is a clue, as is seepage from the weep hole on the bottom of the pump shaft.

The alternator, get your head in there where you can listen, turn by hand. Feel for roughess in the bearings and spin it, listen for noise

You used to be able to buy bearings and brushes and go through an alternator yourself, but you need access to the special pulley puller needed. Not worth the trouble.


"Rebuilt" parts are really really getting to be a crap shoot. WHATEVER you do, buy one for a 70/ later. If you keep your old style (69/ earlier) regulator, you can ground either of the brush holders with a short wire, and use your regulator, but if you do this, you'll be all set when/ if you decide to convert to a 70/ later regulator. One more wire is all that is needed.

PLEASE after you get done, make the checks I posted in this thread below, to make sure all is well:
