hi all, collected my first alfa today. Installed new battery on site and she fired up 1st time and sounded great, apart from a 'werring' sound coming from the drivers side of the engine.

Noticed battery light was on the dash, put a tester across battery and it appears the alternator is not charging.

Does anybody know the easiest way of gaining access to the alternator, Is it belly pan off or inner arch?

From underneath is easiest but it ain't easy. Driveshafts out and it still doesn't go. Think subframe needs removing or maybe a loosening of engine mounts and a crowbar or even both. Proper Alfa job. Not a great place to start with a new purchase. It gets better, i promise.
If you're diy and don't have a ramp, lift or pit then it is possible from the top but I believe the manifold needs to come off! This might be a sensible approach if you have some other work to do or you don't have access to a ramp.
Basically I've never owned another car that changing the alternator beat me and I had to put it into the garage. Shockingly difficult.
Obviously, someone will post now saying they did it on their drive way one afternoon.

Manifold off is plenty of work and I gave up on the alternator, which I could barely see or touch from above (147 1.9 16v jtdm). Fortunately I was by then sure it didn't need attention anyway, but if and when it does it's going to be from underneath - and if at all possible I'll get a specialist to do it. As far as I could work out the subframe had to drop and the rack had to move. In the street... on axle stands... Nah.

Had mine done by AL when it last in, from the top whilst the manifold was off for a deflapping job, and the cambelt/water pump was getting done..

If you've got a cambelt due, then combining jobs from the top makes sense..

If you need new rollbar bushes or lower wishbones, then from below would probably work better...

Not a job I fancied attempting at any rate!

According to eLearn for a 147 16V JTDM it is supposed to be possible to remove the alternator from the top without removing the manifold, just the bits attached to the manifold. Looked a bit tight when I was looking at removing it to change the alternator pulley but luckily managed to do that with the alternator in situ so never got as far as finding out one way or the other.

Speaking of alternator pulleys, check it's working properly. If it's the freewheeling type and it's slipping badly the alternator may not spin fast enough to produce any charge, might explain the "werring" noise. Easy enough to check with the wheel arch liner access panel removed.

From above I couldn't actually figure out how to remove the HP fuel pump bracket, the enormous casting that supports the pump. There are bolts that hold it to the back of the block... somewhere... with terrible access. I suspect it can only be removed c/o access underneath, but the ARB and rack appeared to be right in the way.

If that support bracket could be removed (and that means pump off, belts off) then access to the alternator might be possible.

Inlet off (and the vacuum oil separator) gives much more room, and I think I remember thinking that the starter motor would have to shift as well (another horror) but I still couldn't see how... l gave up once I'd determined there was nothing actually wrong with my alternator anyway.

I'm sure a specialist with a ramp, who knows the cars, where the fastenings are, what does and doesn't need to come off, could do it in 2-3 hours, and for this job I'd find the money somehow. But it's the sort of job that taken to a general garage, who've no idea about the MO, could end in engine out and a huge bill.

Thanks for all the info. I'm getting the help of a mechanic friend to see what he reckons.
Any no this is not the eBay - Skipton car
