alternator/regulator wiring help

i wired the voltage reg back in - green from VR to field term of altern, then blue from VR tied to brown & blue out of bulkhead which goes to ther field terminal ,
volt meter is showing no charge ???? does it matter which field terminals are attached to alternator ?? when key is put to the run position i have power at both terminals at the volt regulator connector. also when the key is on the voltmeter registers and shows draw, but with engine running it shows no charge ???
