Accessory fuse location?

A point in the right direction or some thoughts on this are greatly appreciated. I have an 11 grizzly 700 with no owners manual. A couple months ago I installed a light bar which I wired into the accessory power wire (black n white striped) and it worked great. 3 days riding at Ride Royal Blue night rides. No problem. Few weeks later I was riding at deer camp. Turned on light, worked maybe 2 seconds n out. Lighter/accessory dead also. Checked fuse inline on light bar wire, checked all mini blades in lil box and the 2 larger 15 amp blades adjacent to there. All appear good. Are there more I’m overlooking? Or is there a relay on that stock wire I should be looking for? It seems pretty common people splice into that wire to add mods but a search for problems afterwards has got me no help yet. Thanks in advance for your replies.
