1. Genset not reading out means that the 12 volt signal from the genset hourmeter is not being seen at the Intellitec module. Check the REMOTE quick connect at the genset for corrosion.
2. The BAD thing about an Intellitec, IF it malfunctions, NONE of the shed relay's will close and allow those appliances to have 120 power. so, NO, pulling the fuse will not allow the Power to the Shed controlled appliances.
3. This link will get you to the Intellitec manual and troubleshooting. Doug
