Hi there,
If it isn't the alternator or the battery, it has to be elsewhere in the circuit, possibly a bad earth-connection between battery & body, body & engine, or even between alternator & engine. Ensure that where earthing cables are fastened there is no corrosion, oxide, grease or paint in-between. A good solution to use is a mix of ammonia with some sugar-soap added, (but not too strong that ammonia-smell is overpowering!), rinse with warm water dry well with compressed air or hair-dryer.
A bad earth will cause the alternator to think it needs to supply more voltage & current!
Hope this helps, Stevie-RayG
