Ha ha ha well now you are truly in the brotherhood
, It happens to all of us some sooner than later lol.
try more than once. Here's the deal.
That alternator at lease on the Mondial T earlier models had a first series style, which later was updated to include some new 'things' [that's as technical as I'm going to get, but I will post the Ferrari release notes later].
I, too, had a dead battery, only to find the alternator wasn't charging the thing. So, take out alternator and take to rebuilder who sensed it was an easy rebuild.
put back in and not a good deal later, two weeks, it fried. Rebuilders honored the deal by supplying a NEW one at no cost to me.
now, the one they replaced was identical, can't blame them, but eventually fried AGAIN, three years later or about two months ago.
Brian Crall, who is on top of his game, noted it was a wrong version, and got the newer released alternator. Which I hope is good to go for EVERY.
The new one took him about eight hours to take out and put in total = large labor costs, not to mention alternators don't grow on trees.
about 2,500-3,000 total
