With as much fun as it is to get the alternator out, I'm going to make sure it is right before it goes back in.

Take a look at the thread called "Upgrading the Alternator on a 308" for diagnosis instructions and cross references for the regulator. If the alternator has the heatshield on the back, I don't think it is possible to get at the regulator.

Just as Ed says the reg. is probably bad. More than likely thats what boiled your battery dry.

You can probably change the regulator in the car. Just remove the two screws on the black box on the back of the alternator and the regulator/brush assembly will come right out.

For the last week or so I suspected something was wrong on my 79 308, checked the battery sat. and added over a pint of water. Today I put a voltmeter on the battery, 13.2v engine off, reading at 1000 rpm 14.7v this jumped to 18.6 at 3000 rpm. Question is why dash bulbs have not burnt out, and would the excess voltage cause the electronic ignition trouble. Back out to the garage pull the alternator off.
