alternate alternator
With high wattage main beams and auxiliary lamps I'm running, I'm very close to the output limit of the standard alternator. Has anyone found a modern substitute alternator, that looks and mounts similar to the factory unit, but puts out more amperage?

Ed,
You might be interested in this thread:

It describes my quest for a replacement alternator, and mentions a few possible sources. None of the options is a direct bolt-in replacement, though. In my case there wasn't too much 'creative engineering' required to make a decent job of the installation.

I can get you the part number of my Lucas (delco remy also quoted from memory) that came off my Sport. It has built in regulator so you just bolt it in and use a slightly longer belt and the regulator and wiring can stay in the car ready for when you have to bolt back the oem (bosch or ducellier depending on your car) when the other alternator gives up the ghost in the middle of a night rally!!!!
Just to confirm this alternator has a much higher capacity and was selected by the previous owner to sort out battery charging on full load. What he didnt know was a relay was wired incorrectly so it discharged the car when not used giving the impression of insufficient charge to the battery. Is orted the wirng and have never had a charging problem on the OEM (bosch) alternator I refitted (it camwe in a box of bits with the car!!!! including the regulator lead.... While the OEM is slighlty smaller this alternator is same form and fit sitting under the carb tray.
Please let me know by PM.

Re: alternate alternator
Note that the next weakest link is the V belt. I would not go over 45 amp.
There is a 90 Amp unit that fits. Someone here in Holland put one in a couple of years ago. Only Fulvia I know which had a fire in the engine bay as the gentleman forgot to change the wiring to handle the 90 Amps.

Thanks to all for the suggestions and the link to the earlier thread.

Hello
A long time since I have been here I'm afraid, but you'll probably be seeing a bit more of me now.
Your question Ed prompted a memory.
When I was at Evolution Engineering we had dismantled a small FIAT, a 127 or 128 I think. I looked at the alternator as it seemed familiar. In a way it was. the body was identical to the Bosch 28A alternator found on SII Fulvias (and also on Fanalones) but it was rated at 33A. I thought this worthwhile. All I had to do was remove the front (pulley) end and replace it with one from a Fulvia - having first made sure that the bearing was OK of course.
The other mod we used to do was to fit the 55A alternator from flat-4 2000s This is a bit of a tight fit and you need a 750mm (instead of 775mm) belt.

I suspect the Lucas alternator is the 55A beast Paul has just mentioned. It has a larger pulley hence the belt size change and is a little fatter (measured this afternoon 13cm v 11cm for a bosch) - and it has 55A stamped on it!.
I will post photos once I have got them off my phone. The part number is difficult to read as the lable has worn a bit. But the original invoice(!) has LRA313 as supplied by Lucas themselves.

No, the 2000 alternator was Bosch, as was all the electrical equipment on SI and SII Fulvias.. Because it was of much larger diameter (I think that the pulley was the same as that of the Fulvia) a shorter belt was needed. On my own car I have a Japanese alternator that came from a Mitsubishi Colt in a scrapyard. It was a bit fiddly to fit, but it's slightly smaller and lighter than the original and rated at 60A.
