Okay guys, I recently removed and rebuilt the alternator in my 348. F-Chater jm3 rebuilt the alternator in his 355 using updated parts. Here is the thread were he listed the parts he used http://ferrarichat.com/forum/showthread.php?t=124504&highlight=transpo The old Transpo regulator (part #IN220) has a tendancy to go bad, and I think they are a piece of junk. I had the alternator rebuilt a few years ago and the shop that rebuilt it used the standard Transpo parts and they ended up failing on me again. The battery light would also come on when I would get into the upper rpm's. Well since the alternator crapped out on me I wrote down the part numbers that jm3 used on his rebuild and went to the the alternator shop to order them. Here are the Regitar part numbers: regulator - #VRH2005-4A rectifier - #RN-02 Well when I ordered them the supplier to the shop told them that a company named USI made a better regulator than the Regitar. Not that the Regitar was a bad regulator but that the one USI made was just better. So I figured why not and ordered the USI regulator. That way we have two alternatives to choose from over the crappy Tranpso part. I still used the Regitar rectifier though. Here is the USI part number: regulator - #00632, 71-30003/SCP Unit2 electric in Ventura was a big help in getting the parts for me. Since I had all the stuff I figured you guys would like a how-to on the removal and rebuild, and yes I did take pictures. Oh yeah one more thing, this is for the Nippondenso alternator, so you can use the parts for a 348 or a 355.
