2008 Tiffin. The chassis starts the Genset. It takes 12 volts continous for the Genset to run. Gensets do not supply 12 volt power once they are running. So, you got the Genset started with the Battery boost button. It takes the COACH batteries to engage the battery boost. So with the battery boost button pushed ON, your Genset started from the coach batteries and the coach batteries supplied the 12 volt power to keep the Genset running. Once you released the Battery boost, the Genset and Chassis side LOST the 12 volt signal. Hence the Genset died. Have you tried the same operation but start the Engine first and leave ON? Then boost to start the genset. The Engine alternator will supply the 12 volts required to keep the Genset running. Doug
