Same problem on my 2015 Sector 550. Full charge in battery. No dash lights, no horn, no start, no nothing. I thoroughly cleaned every connection at the battery. The bat compartment looked new when I was done. SAME problem. NO change. So I used a known GOOD fuse/relay unit. Same problem. NO change. I even attempted a jump start from a running vehicle. Same problem. No change. So I took it to a real Hisun mechanic who replaced the battery and it started right up. (I couldve sworn I did a LOAD test on my battery. I must've been wrong. I NOW keep the UTV S/S on a trickle starter each time I park it. This unit only had 300 miles on it when I bought it from a friend who didn't use it much. I'm learning as I go. Good luck.
