Electrical gremlin help needed Options

So the other day I decided to take my 914 out for a drive. About 20 mins. into the drive, the alternator light came on so I stopped and checked the belt and it was there. Started it back up and drove it home. On the way home, anytime I would press the brake pedal, the temp gauge and fuel gauge would drop to zero.


Drove for another 20 mins. until I got home. Turned it off, and when I turned the ignition back on, neither the oil or the generator light would come on, but the car would start right up. So I shut it off and when I got out of the car I noticed the right front turn signal, marker light and tailamp were on. So I disconnected the battery and that's where I am at. Anytime I hook the battery up, the right lights come on. The car starts but the oil and alt. light will not come on.


Any ideas of where to start looking? Any advice would be appreciated.

Thanks,
Patrick

Update:

I found the voltage was 12.4 before and after starting the car. So I swapped out the voltage regulator from my parts car onto it. Now I am getting 13.8 volts with the car running. I still get no alt/oil light coming on and the battery gauge in the center console always reads zero. The wipers are working.


But now the alternator light is backwards. When I fisrt start the car it's not on and I get 12.4 volts but when I rev it a little the light comes on and the fuel gauge goes up to its normal setting and I get 13.8 volts. Weird. I also tightened the bolt under the left tray area.

By the way, it's a 74 2.0 with dual carbs and the battery, clock and temp gauges in the center console. Any other ideas would be great.
