1994 Chevy Beretta no power at L terminal at generator plug

1994 Chevy Beretta Z26 with a 3100 engine VIN M
I have rebuilt my engine, and after reinstalling it, my car would not charge. I had the generator checked twice and it is good. I have no power at the L terminal at generator plug to ground with ignition on. I have checked both fuses no. 9, and no. 4 both are good. With the ignition switch in run the voltmeter in dash, and my voltage meter both read the same. I pulled the instrument cluster and checked between Term “Z" and term “D" with the ignition in run, and still read the same as the voltmeter in cluster. I have checked all connections on engine and all grounds I could find, all are good. Was hoping there is some thing else to check or do. I do not what to replace the cluster unless there is no other choice.
