Hello arnietwo,
I don't understand what you measured.
The battery with the motor not running has a voltage around 12,5Volt. If you start the motor this voltage should rise to between 13 and 14V. If this does not happen, there is a problem with the alternator or with the voltage regulator.
In the german Barchetta forum I read that if you have the 65A alternator, it is easy to change.
BTW, is your Barchetta yellow? Mine is yellow and in March I was in the area of Calpe and I crossed with another yellow B on the road between Calpe and Javea.

Hola,
the battery warning light is on constantly on the dash. Battery has drained so i have now replaced it with a new one, but still the battery light is on. I took it to a garage and put a meter on whilst running and it showed 12, the guy said it should be a Reading of about 40. So we now think its the alternator problema.
Ive had a look under the car and the alternator is well tucked away and difficult to Access.
So can anyone answer a few simple questions for me before I attempt to replace the alternator myself.


Do i need to worry about timing belt, when i slacken the tensioner,
Or what it the best sequence for doing this job ? Is it tensioner then bolts etc, how many bolts are there ??
General comments to help me would be appreciated.
thanx Dave

I replaced my alternator a couple of months ago. It took me about 5 hours, being an amateur with wrong tools and crawling under the car. I found cheap alternators here
I know they have a Spanish site as well...

This is what I had to do:
1. Remove right wheel
2. Remove plastic wheel arch
3. Loosen the aux belt tensioner (you need to pull HARD) and remove the aux belt
4. Remove the second part of the exhaust manifold
5. Disconnect lambda sensor and gearbox reverse indicator.
6. Undo the two bolts from the alternator. The one at the top is really hard to reach.
7. Remove the starter motor, four bolts, one of the top bolts is difficult to reach.
8. Loosen the two lower engine mounts and lower the engine about 5cm. This will move the drive shaft a little bit, allowing the alternator to be removed.
9. Removing the alternator is possible, but very tight. You can remove it by pulling it towards the gearbox and then pulling it down between the drive shaft and the bulkhead.

Just let me know if you need any details. I don't have any pictures of the process but I still recall the details of the process...

thanx, yes i downloaded the workshop manual and thats what they advised. But as u say its harder than first appears. Point 6 the top bolt i cannot loosen ??? i can get the socket on the end but there is no space to turn it. Did u accomplish it from underneath or above. Above appears even worse as the transmission fluid reservoir is in the way ?
Likewise I cannot get one of the exhaust nuts off.
A garaje would just torch it off but ive not got those facilities.
So i spent 3 hours this afternoon on it and Little success, so hopefully tommorrow i might have better luck !!

The exhaust nuts are impossible to get off. I had to drill one of mines...
The top bolt on the alternator can be removed from underneath. It's a long bolt, and you need two spanners, one to hold the bolt on the side closest to the wheel, and another spanner to undo the bolt on the side closest to the gearbox.
This is by far the part involving most blood, sweat and tears. It's extremely tight and you barely have room to move the spanner.

I ordered the CEVAM 4496 for my -97 B. It really depends on if you have AC or not. Check ePer to see the Fiat part number, those numbers are available on Mister auto's site. The CEVAM 4498 seems to be a good match for most older Bs.

The gearbox detail are available on page 22-23 in the service manual, the type should be C.510.5.17. If anyone gets a hold of the "Overhauling gearboxes" manual from Fiat please let me know. It's on eBay but I have not yet found anyone willing to ship to Sweden

Another few hours spent under the car these past 2 days and have eventually fitted the Alt and refitted exhaust etc. Again no need to take starter motor out or lower engine ???


Main problema experienced was inserts in the mounts of the alt not matching up with space available on mounting lugs. So Alt was in and out about 6 times fine adjusting those inserts !!! Pain in the arse!!


Then when everything completed i started up the engine to then hear a horrible noise from pully or nearby !!!


I had enough **** for the day so switched it off and opened a bottle of wine !!!


Does anyone know if the noise will just be the new alt ?? do I need to spray some WD40 into the alt ??


Any suggestions ??
