Yes, I've checked the battery.... It tests good (it also lives on a battery tender, when not being ridden)

I am having the exact same issue with my Hisun 750 Tactic ATV, not power to anything! Started it to move it out of the garage, it ran for about 5 seconds then stopped, and now no electric power to anything.... all of my fuses check out good, with my multimeter.... I also have a new Main Relay on order from Amazon, waiting for it to arrive from China - hopefully that solves my issue. I want my unit to work.

I hate to bring up an "old" thread, but did you ever get this solved? I have exactly the same issue with my 2021 Hisun 750 ATV. I attempted to start it a week ago, it turned over, then just shut off completely after abut 5 seconds...No power to the dash, winch, lights, turn signals, etc. will not turn over or start. Shorting the solenoid will only spin the starter motor, and not actually "start" the vehicle. I read somewhere else about a "dash ECU Fuse" causing a similar problem - mine tests fine with my multimeter.... I need my machine to work!
