I've had my AB400 and VagabondII for all of about 10 days now. All this time the Vagabond has sat plugged in staying charged until I FINALLY get a chance to use it.
I unplug the Vagabond from the wall socket and set it next to the lightstand, and after plugging the AB400 into it I flip the Vagabond power switch to "SLOW", turn on the AB400 and just as the AB400 fan begins to rev up POP! and everything goes dead. 
I checked the Vagabond and there are no green or even red lights glowing. Switch on, switch off, nothing. GREAT! I take the inverter out of the bag, locate and check the two 30 amp fuses, pull them, and find they are blown.
So I run to Auto Zone (automotive parts store for everyone else in the world reading this) and there I pick up a 5-pack of ATC 30A fuses (good to have some as spares in case this happens again, right?)
When I get home and try to install the new fuses, as soon as the fuse tabs touch the fuse port there is major sparking reminiscent of the wicked witch of the west trying to touch Dorothy's ruby red slippers - the sparking was so bad it scorched the fuse tabs.
Anyone ever heard of this?
