Voltage Regulator- Who makes a good one post Covid?

First thing to do before you start throwing money and parts at it is to do a bit of troubleshooting. Unplug the VR and see if the voltage drops. If not you likely have the green field wire brush or wire shorted to ground, causing "full charge."

Have you done anything lately that might have moved/ caused a short in the harness? Replaced the alternator?
