Careful guys, you aren't going to want to pot, or goo if you are more
technical, the heat sink. It needs to have lots of airflow.

Hey Jong,

That's right. My plan is to find the problem with the
board. Then come
back to the group and come up with a way to protect the
component or
group of components that continually fail. If that doesn't
work then
it's off to plan b. I'm not sure what that is yet.
This is a pricy unit and I would hate to see my friend lose his
investment.
If the motor is OK, then get yourself a PWM controller, pot
it in your choise of goo, and have at it. Virtualvillage.com
had 30A PWM controllers for soemthing like $20 one time...
Here's one from QKits. The heat sink might be a bit of a
challenge if you want to pot it.
