I have trouble with my GE 2010 also , the two fans on the roof needed the copper contacts adjusted to line up with the two silver contacts on the engines body to get them to work, there should be around 4 volts on the silver contacts when the rpm's are above 4 .
My engine also does not smoke properly , I need to strain to see the tiny amount of smoke that comes out. I don't think the smoke unit fan is working , had the smoke problem since the engine was new. I took it to a service shop and they have a three month wait before they can get to it. How hard is it to trouble shoot and repair? everything else is working properly.
