Simple way to trace it is with a trace Tone and probe!!
Did you ground the I lead at the ALT to check Continuity???? Alt light lit when keyed??
Did you check the I lead with a test light to ground???? Key it and see if the test light lights. If good it will be DIM
Connect an old fashioned test light from ground to the I LEAD and key the car. Does the ALT LIGHT COME ON??? Again it will be DIM
You have to check this stuff out or you will be chasing balloons AGAIN!!!
904 GR/R C403 out on 904 LG/R slight color change through connector.
Trace tone will pin point in 2 seconds if you have an open.
Simple test if you have constant battery on the charge lug and the regulator A punching and the 2 S lugs connected together do this
Connect an old fashioned test light or a bulb and socket like an 1156 and hook one lead to the cars PLUS SIDE OF THE BATTERY. Then connect the other side to the I terminal of the regulator. The light should come on. Then start the engine and the light should go off. If it does go off the battery voltage will clime to 13.9-14.8. This will tell you the alt and regulator is OK. And if it works it will verify your charge indicator lead and alt light is the issue. Did you check fuses that feed the CHARGE LIGHT??? Did you check the BULB IN THE DASH??? It gets key battery through the ignition switch.
