I believe that your 70 had an internally regulated alternator. That started in 69. Chuck

With the car running (with RPMs above 1500) what is the voltage output of your alternator? It should be between 13V - 14.5V. A bad battery can bring this down, have you had your battery checked?

Also check your main electrical connections & grounds; the mating surfaces should be free of dirt & oxidation and should be tight.
