I installed a Wagan Smart AC 400 watt, 2.1 amp inverter in the nose cone today. It has two 120V outlets and 2 USB ports. Photos below. It's powered from the battery post under the nosecone. I plugged in and sucessfully tested several 120V devices. But when I plugged in a 12v power supply to do another test of the rear lighted T, it beeped and shut down. The beep indicates insufficient 12v power and in those instances the Wagan shuts down. I tested the the power output of the 12v battery post and there's no power, so I assume it's fused. I won't have time to check the fuse box until tomorrow so I'd thought I'd ask. Is it fused? BTW, the 12v battery is working fine -- the car starts as normal and all of the 12v powered accessories power up as they should. That leads me to believe that the post under the nose cone is fused. The red thing in the photo below is the post i'm talking about. The little red vinyl boot is removed and power is accessed by making a connection to the bolt under it. Here are photos of the Wagan installed in the frunk.
