So I was out mucking around with my Fusion system today and I see in the WiFi section that if you turn WiFi "On", the default in the WiFi settings is to keep the WiFi on even when the unit is asleep (I think this confirms that the Fusion is always "on" and drawing power, just in "sleep mode"). I know that several folks who have the Fusion in their rigs have reported that their chassis battery seems to drain VERY fast when parked and not connected to shore power. It might be worthwhile for people to check this setting and change it from "Always" to one of the other options (can't remember what they are now but you will see when you are on that screen). WiFi can be a real power hog, so this may be contributing to some of the battery drain people are experiencing while the Fusion is "sleeping".
Summer is almost here! Drive safe everyone.
