Gauge cluster blowing fuse

[Detroitpower]

Hey guys, my cluster quit the other day, ive tried 10a fuses and they keep blowing a short way down the road so i put in 20a and same deal, tried a 30 and it works fine but smells a bit like burning lol. With a good fuse everything works as it should except the volts shows discharging at 10 or so. I have 2 pretty new batteries and it starts and runs fine, everything functions. I know it could be almost anything and electronics are far from being my forte, but maybe someone knows where to start looking? I have a 1000 mile roadtrip coming up hauling a trailer so id really like to have at least my temp and fuel gauge working, i can rely on my gps for speed.

It is a 99 6.5 with an NV4500 and 4x4.

Thanks in advance!
