Hello all! I'm new here, 2010 E350 ford cutaway chassis (it's a 24' shuttle bus) V10 gasser.

On the van it's got two batteries, a normal battery to start the engine, then a second deep cycle marine battery. They're both wired in parallel to a panel above the drivers seat and so I bought a 1500 watt inverter and hooked it up to the terminals in that panel. All seemed well and good but then I noticed my reverse lights were no longer working and my fan system had blown too, no AC, no heat, no fan. I suspected I blew a few fuses but they all look totally fine, however some of them aren't getting power.

My suspicion is that I've blown a fusible link somewhere, however I've only owned this van for 2 weeks and don't know where to begin, or even where they are! Any help would be appreciated and any alternative hypothesis are welcomed! Thanks all!

I spoke to one mechanic and he was the one who suggested it may be a fusible link, my problem now is that I can't even find where those would be in my bus. I found a couple helpful videos on how to replace and test them though.
