GE Evolution Hybrid help fixed with video of it running

Sometimes PC boards blow on their own, but usually there is something else "downstream that causes the problem.  I would carefully check the smoke unit for shorts to see that the new board won't also self-destruct.

Yea what i am afraid of pluggin in the smoke unit and then blowing up the board i just spent 44 bucks on ..I try testing the smoke unit...

I tested the smoke unit then i looked at this a little closer ...You see the mark on the heat sink its from the wooden base that you screw in to the chassis .. The screw from the base hit the heatsink and cracked it ... The second picture shows the hole and that is where the heatsink is attached to  too... I guess you never seen it all ..

The screws are two different length, There was a warning to make sure you did not bottom the longer screw out on the circuit board when the engines were released. Looks like the previous owner blew it

hahah classic yay me
