from your first post,
>> I think it may be the light on the dash.<< You were not clear WHAT you think is the light, but it sounds like you have a Gen warning light.

On the inside of the bulkhead connector, the Brown wire splits into two wires. A brown wire goes to the dash gauge connector and to the Gen light. A second wire is a resistence wire that goes to the ignition Switch. It is shown as Brown/White in the wiring diagrams, but could be a different color.

This Brown wire that used to be connected to #4 on the old Voltage Reg should now be connected to terminal #1 on the new SI Alternator. You should not be making any other changes to this wire. If the gen light worked with the old 10DN alternator it should continue to work with the SI alternator.

Right on Richard, the confusion may have come from the two posters, the first one has a light and the second one(post 7) has the battery gauge. That's how we got onto the fuses. VV
