I could easily just be a weak battery.
If you're handy with a multi-meter (5 quid from Maplins), you can check the voltage. IIRC, 12.7V is a good battery, 12.6 weak and 12.5 poor. Test while the engine is off. Fire up the engine and check that the voltage is immediately higher; say somewhere about 13V, but It will drop to way below
12V while cranking. The voltage rising above 12.5-12.7 with the engine running will confirm your alternator is okay. The lower the figures, the weaker the battery.Betcha it's just the battery to replace.
Good luck, Paul
I'd imagine it's just the alternator (diode pack ?). The battery has eventually weakened itself by not being charged enough, and won't turn the starter.
As Paul said - get a voltmeter on the battery - a good voltage on charge is just over 14 volts usually (ish). Since the charging light is on continuously, then this'd seem to confirm the charging cct, but till you test it properly, you'll just have to wait and see.

just had to have a brand new starter motor after having same problem starting after only 2 days. Would have cost £175 but luckly had 2 months of warrenty left.
