Blew a fuse nedd to know where

I suspect you will need a replacement ecu/ignition system and voltage regulator assembly for the battery charging plus of course your blown fuses. But, won't hold your breath but you may be lucky.
Check all of the fuses first.

define "stopping". If it involved using the new ignition switch, then I think a return to the dealer is necessary. You know it takes 3 times for them to get it right?

Hey Michele,, if the original battery lasted this long.. you are lucky,, just replace it. >>> Always use the exact replacement battery<<<<... your quad is designed to take the exact size and amperage rating,, trying to change this is inviting too much trouble,, When you get a new battery,, it will be charged unless you purchase one online that comes with the acid pack,, EITHER WAY - put the battery on the trickle charger for 48 - 72 hours BEFORE you use it.. This will extend the life of the battery a bunch and make it a stronger battery,, ..(this is from too many years of experience.)

If you look at the picture - 29, 30 & 31 are the starter relay, main fuse and probably the bolt that holds it to the frame. When that fuse blows or that relay goes out - it's over. Not going to start. If you have a standard test light - attach the clip end to ground (frame of atv) and then put touch the postivie post of the battery to verify that the light is functional. It will light up if the battery is good. Next -follow the red cable to the starter relay in the diagram. Where it attaches - check for power. With the key off. IT should be live without the key in. It's on standby in a way. If you do not have power at the other end of your positive cable - your cable is shot. If you do - then you will have someone turn the key and check to see if power is coming from the other post off the relay (that would go to the starter and make it engage - if the square standard fuse in that relay is not blown - but power is not coming through when you touch the key - it's probably the relay. Your safety switch among other things can prevent the engine from starting as well - along with loose cables and grounds (always do a thorough check of all wire connections and grounds - one loose ground can mean a nightmare sometimes) - if you give that a try and do not identify the culprit - just comment or reach out and I'll take you through the next steps.

Your starter relay -


4SV 81940 12 00

check to see if voltage is coming off the stator while running, AC volatage, from all 3 wires. if thats good you prob need a regulator/rectifier.

Look for a bad fuse or bad connection on the wiring that feeds power to your front lights. Also check for a bad ground.

Until you find fix you can always splice a wire into the hot rear light wire and connect it to your front lights.

Check your battery cable and fuses first. Sounds like a loose connection at the battery.

Sounds like you blew the fuse under the seat

trace red cable from battery there should be a fuse holder that twist to open.

sounds like you blew a fuse. also check to make sure the battery is fully charged.
