09 Ducato 3.0 jtd charging problem

Start up engine from cold, battery light stays on. Switch off and restart, battery light goes off. After that no problems until van left a few hours and then problem repeats itself. Is it likely to be an alternator issue or something more ominous?

Does sound like the alternator, you need to get a meter on it and measure the voltage under the different conditions.

Is drive belt tight and in good condition?
