Unlike a Car, Tiffin powers items Tiffin installs NOT THRU the chassis fuse box. The Items you listed are powered thru the Coach Battery and the chassis, but required the coach batteries to be powered up to engage the relay/solenoid that is activated BY the chassis ignition on side of the key switch. There are separate fuses for those items but they are a Tiffin installed fuse box. You need to get a quick jump to the dead coach batteries using jumper cables. Once you have 12 volts to the coach batteries the Emergency start switch will be able to activate and use a toothpick to hold switch ON. Run the chassis engine for about 20 minutes and that should be enough time to get the Genset to start. Once the Genset starts, leave it on for about 4 hours. That will be long enough for the Inverter/charger to charge up the coach batteries to full. Remove the toothpick once the genset starts. Doug
