Went to AutoZone this morning. Their alternator testing requires the removal of the alternator from the vehicle, they won't test them in-vehicle anymore, apparently because the city got on them for operating a repair facility without a license or permit or somesuch, or at least that's the story they gave me. 'Sploder is sitting outside with the battery charger on it now, and I'll leave it on the beast until I go home tonight. Just a few more days and I should be able to fix it. Unless something else breaks.
