That '02 Spyder CC I bought last week I drove for about and hour it began to die like the alternator was not charging. It didn't actually die all the way but all of the lights slowly went out except for the headlights and the car became very sluggish and very slow shifting. I crawled to a hotel and the next morning it was fine- volt meter reading 15 volts. I drove it for five muntes and the volts went down to about 11. I just assumed it was the alternator. The dealer picked it up and has not been able to locate an issue and are taking it to a Maserati dealer now. Has anybody else seen this or have a suggestion? It's a stupid question I know, I'm just a like anxious to get the car back and figure this out.
