[RE-wrenches] Intermittent charge 4024

[Jay]

Hi Mac

No don't recommend replacing internal fans 

But I have installed external 120v muffin fans on the ends. 
Seal up the vents around the ends so it pulls air through. 
Hook the fans to the genny input. 
Quick and works well

I observed this for about 5 minutes relatively consistently  I also noticed the body of the 4024 was very hot, and I couldn't feel a fan moving air through it.
