With an alternator system ‘Hotrod’ tells us to never remove the load (battery) from the system while engine is running. The battery acts as a load for the alternator and without it, the alternator output will jump way up and can trash the regulator. You should see battery voltage using a voltmeter between a battery post and its connector, alternator output voltage if engine is running, but reread first part. Were some of your voltmeter readings (36 volts) taken with the alternator disconnected from battery?
