Thanks for the replies.
There are new grounds from VR to eng, from eng to frame and frame to body. The amp meter was long ago bypassed and replaced with voltmeter. The dash power feeds through a bulk head stud in firewall and removed from wire harness bulkhead connector. I went ahead and changed the alt out for know good one and same thing. So I think I will install a relay like suggested for now and open up the dash to try and figure it out. Any Ideas were to start? A little more description of problem: Start her up and the voltage meter will slowly rise to about 14 volts and then start to fluctuate between 13.5 to 14.5 volts in a pulsating 1 second intervals. If motor is reved it will kind of diminish until rpms are steady then go back to fluctuating. I hate electrical problems.
