1974 Lemans Dash Lights

[pontiaclemans74]

Hey guys, I have been struggling trying to get my dash lights to work. I replaced the headlight switch, all the bulbs are good, and the fuses are good. I have power on only one of the prongs that plugs in to the printed circuit board. Is this my problem, or is that correct? or should they all have power? The one prong that has power goes to a spot on the back with no bulb, and I am not sure what would go there but there is a hole for a screw or something to go in. Any help would be appreciated, thanks.

You may have a blown circuit board. Try to get a copy of the 1974 factory shop manual that has a circuit diagram. If it is a blown board they are available from www.amesperf.com

When I hook power to the board and test the other end of the wire it lights up that I have power on each different strand so it seems to be functioning correctly I think? I was just wondering if anyone knew whether each of the prongs should have power or just one?
