Who would like to beta test one of my new voltage regulators?

Latest batch works on the bench but runs into issues on the car. At least the regulator still passes a bench test after testing on the car, which is an improvement over what happened the last time. The plan is once I have one working on the car to run it in for a while before making the others available.

I wonder if I can find one of those alternator test benches you see at parts stores, secondhand. That would avoid the risks from testing on a car, while bench tests clearly don't cover all the bases.
