Ducati 2.8 diesel 2001. Not charging

[removalizer]

Replaced alternator only 11v showing when running charging light not on when engine off also only 1.5v coming out of the small wire from the back of the alternator I presume this is the warning light wire ?

rem

Have you got a bulb-type test-lamp to take a 12v feed to that small terminal?  [One of only two?]

Has the dash bulb blown?

[Simonh8606]

have u checked fuses?

[removalizer]

Fuses in the dash are ok not had chance to check charging light bulb yet, but could you tell me if the supply comes from the bulb or the alternator ?

[Angus]

rem

The excitation current for the alternator normally comes through the bulb.

That's why I asked those 2 questions- what's the answer?

[removalizer]

Sorry Angus I haven't had chance to get the dash out yet looks like Tues when I will know (apprentice at college on Monday) Just realised what you mean by bulb type test lamp.

[Angus]

rem

That's understood - but have you got a test-lamp [or can you make one] and how many terminals are there on that alternator?

[removalizer]

Angus I'm glad you asked that as my apprentice said there were more terminals on the alternator than on the wiring
