Replaced rectifier and battery brand new and after a 30min ride battery still drained and would not start back up! What may be my next step seeing it did run for 30mins and after shut off would not crank over from battery drained?

You need to get a voltmeter to test the charging system......and your new battery.
First, charge the battery fully. Should be 12.6 V or a bit more.

Then start the bike and test the voltage at the battery.
At fast idle, if it does not read at least 13.4 volts, then the rectifier wasn't the problem to start with......or your replacement is bad. Burned out stators are fairly common.

Have you checked the connection at the OTHER end of both main battery cables ?

You might need a shop visit to get it sorted out.

What bike is this....Some Honda models were known for issues with reg/rec. Suzuki too... theirs was a cost saving and consisted of running excess voltage back through the system causing the r/r to burn out.
