My voltmeter shows ~11V while engine running so it is looking like a new alternator, but really, over $3K for a new one?! What is the most common solution, rebuild, delco equivalent? Any help would be appreciated. Thanks, Greg Image Unavailable, Please Login
Greg - - - don't fret Your alternator can be removed, rebuilt to perfection and reinstalled for a very reasonable price. I just did that complete dance (with Eugenio) about a year ago. Check with "the usual suspects" in your area as regards price of rebuild - and price for R & R if you're not wrenching yourself. Cheers, Hank
The most common solution might be a loose belt! As indicated though there isn't anything special about Ferrari alternators that any good starter / alternator specialist can't fix as long as the casings are OK. Internally they are mostly standard Bosch (or Denso I think) units.
That is outrageous but I'm not surprised. I keep saying how expensive the parts are there from the usual suppliers in the US. Try Euro spares here in the UK, it's about a third of the price for around $1000 USD. Its the same as used in the F40 and looks like they have one buy enquire and let us know. http://www.eurospares.co.uk/searchResult_one.asp?S=139421&TM=1&TMo=391&TA=1&TB=21146
If you absolutely must buy a new one... check ebay, there's one listed for $275 right now that might work for you. 1990 Ferrari 348 Alternator Brand New 90 348TS TS 348TB TB 91 92 93 94 | eBay
As above, 99.9% certain the thing can be rebuilt for less than 10 % of even that figure. I had my 328 alt rebuilt a couple of years ago. The cases seem to be unique (at least I've never seen a cross reference) but internally its just standard Bosch kit. New bearings were less than £10, a new regulator/brush unit about £15. A new unit from Ferrari is about £1100 I think....
also starting to wonder how good "new" Ferrari alternators are that have been sitting on shelves for awhile. do they degrade just sitting on shelf?
A recent pose in the 348 parts exchange...I'm sure there are others also... http://www.ferrarichat.com/forum/142475600-post475.html Dave
Even the casings are standard Bosch. The only unique part is the pulley which is smaller than on most cars (at least on 328). There should be no reason to ever buy a new alternator on these cars.
There appears to be quite a lot of T/348 alternator information on ferrarichat. I am presently in the process of replacing/upgrading my T's alternator. An exact fit replacement is the CS130 (GM) 105 amp alternator for a 1992 Dodge Monaco, available from, e.g., NAPA on their website. I am using this but will be upgrading the stator using the 140 amp custom-wound stator from alternatorparts.com. I am also adding in my own external bridge rectifier, similar to the Quicktifier product of alternatorparts.com, as well as a metal heat shield to protect from the exhaust heat and also any possible oil dripping from above. With all this, I hope to have a robust solution.
Same as for 1992 Dodge Monaco, except for the pulley which needs to be replaced with the original pulley.
I think here in Europe when you buy a new or revised one you need to turn in your old one... that is how it works here in NL Personally I would take it out and revise it. I prefer to keep my own stuff. Should not be more the 100 USD for revising it. HTH MvT
Will most likely remove and have it rebuilt (we call it that versus "revising" ;-) at a local shop. Thanks for the input. Cheers, Greg
Just a suggestion, but check the earth of the alternator. On my 3.2 the voltage was low, got a new alternator ( thru' a Bosch contact - so cheap) when I went to fit it, I found that because the alternator mounts have rubber bushes it earths thru' the belt adjusting strap. Whoever did last adjustment had not tightened the fixing on to the cam belt cover, it was loose. The stud had been "spark erroded" half way thru'. Not sure if T installation is the same.

Removing the alternator and having a local shop rebuild it worked perfectly. This $100 option was much more palatable than the $3022 replacement from Ricambi, and it comes with a lifetime guarantee from the shop here. Fortunately, the alternator is at the bottom of the engine and pretty easy to get to. The only issue was the gearbox control cables hanger clamp that blocked removing the long alternator bolt believe it or not! The Italians clearly do not think of maintenance when building cars!

Sweet price! Cool that it worked out! I hate agreeing with you on your last point. Walked into this serveral times by now. Try to get to coolant union 106241 or your front silent block. Before you get to the affected part you almost need to de-assemble half your vehicle still love doing it though!
