Angry 1998 Jaguar xjr Alternator Charge Light

I have the charge light on all the time on the dash and display saying not charging. This is what i have done so far.The battery is charging checked with my multi meter.

1:New Battery - Light still on
2:Used good alternator -Charging light still on
3: Checked correct voltage at pin 2 on multiplug - OK

I have unpluged the multi plug from alternator (generator) and the light still stops on . Is this correct as i believe the alternator supplys the charge light with a feed?


If any one has any ideas please let me know as its really bugging me

Thanks in Advance Kev

Hi Kev
Your problem maybe in the wiring harness from the Generator to the Instrument Pack's Warning light.

Here is a JPEG file showing the 2 wiring diagrams -
Fig 03.2 Generator's Regulator, Suppression Module, ground and wires color coding (wire coloring for wire going to warning light is Slate with White stripe)
