My 78 bronco has some voltage issues. The lights will pulse while driving and at idleing Rpm. I have put a new ground to frame and a new Voltage regulator on it. Wondering if anyone has ran into this problem any help would be appricated.

I would check the alt output and make sure the belt is tight.

I have checked both the voltage and the ground. I was wondering if it could be in the ignition switch?
