Hi Niall, rather late reply but your symptoms suggest an alternator rectifier problem. Alternators actually produce 3 phase AC. The rectifier has 6 diodes which form a full wave conversion to DC. If one or more of the diodes has blown then the alternator will only produce partial rectification. This will cause the indicator lamp to be partially illuminated.
It may be possible to fix by replacement of the rectifier stack but there are various designs which may include the controller. Repair does require heavyweight desoldering of the rectifier from the coils. A big soldering iron is required and some unsoldering/soldering skills. Simpler to get the alternator checked and if faulty get an exchange unit. Something to check first though is the wiring. There are two wires usually that connect to the alternator. The big wire is the charging lead that connects to the battery, sometimes via the starter solenoid battery connection. The small wire is the wire that gives feedback to the controller of the system voltage. Sometimes this is connected directly to the battery or may go back to the ignition switch. If this wire has an intermittent connection again the indicator lamp will glow. Hope that helps.

I suppose it was a long time ago I may have misremembered something! But it was definitely something along those lines (not that that is much help to anyone either!)
