Would a bad alternator cause headlight flicker?

I am having a similar issue.....I but the weird thing is it all checks out fine with the ohm meter. Almost nil voltage drop through the bulkhead connections.....cleaned them up and die electric greased them. No drop on the field wires. Case is grounded on the regulator.. good reading with ohm meter from battery negative to reg case. Good clean new cable from engine to bbattery and bat to body.

Charge voltage is 14.8 or 9 while revved. Engine warm. I just think tthat's to high. Iam an electrician by trade.....i have went through this whole thing with a meter...only thing i can think of is new voltage reg sucks. Anyone make an adjustable Solid state?
