check the 100 amp fuse on the chassis rail

Unless you have two separate faults, it won't be the 100A fuse: all that does is stop the battery from charging. More likely to be the dashboard supply. You say you've checked 'the usual' fuses; does that mean you've checked all the fuses?

The alternator self-excites above about 3000RPM: does the ignition light go out after then?

hi.

I've checked the 100 amp fuse both of them ok dashboard fuses ok ignition light does not come on when starting and battery light glows, i was talking to an ex-tvr technician he said it could be the regulator in the alternator or the one in the dash had a look last night could'nt see one behind the dash totally confusing!!!

Is the alternator actually charging the battery?

Mine has just started doing this exact thing.

Anyone know the outcome?

Cheers.
