@ThatGuy posted:The one difference I see with your DC motor mount and mine is I can simulate a load with a drive wheel and slip clutch. I have seen boards that need to heat up to stop working.
I have a left hand that holds the flywheel if I need a quick load. If I need a more sustained load, a power resistor across the motor does the job just fine. This has been added to over the years as more situations for testing come up. It started as a simple board tester. If I knew it was going to grow like this, I'd have planned the layout better.
