The po wired in a 10si. #1 goes to idiot light via the factory brown wire. #2 goes to starter batt term . Alt Batt term goes to starter batt term . Starter Batt terminal goes to + side off battery, from there to the horn relay.

The idiot light comes on and slowly goes dimmer with increasing RPM. Is this an idication of a bad alt or bad wiring design?
