Borrow ATV to do some field spraying but it keeps blowing the 30 amp fuse. Sprayer on its own power. Replace fuse, runs for a couple of minutes then blows, thoughts?


Check the rated amp draw on the sprayer. It might be rated higher.. If the sprayer is wired with too small wire it might be causing too high an amp draw..see if the wires are hot? How is the sprayer grounded? Make sure ALL the wire connections are clean and tight. Use a blade type fuse in a waterproof holder. Recheck all this and repost with the results.

Yamaha Grizzly 03-660. Why doesn't it start?


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.

After replacing battery,extra installed lights come on,but turn of ignition switch ,nothing.


You may have blown the main fuse for the starter relay. Easy to do. If you follow the red positive battery cable to the starter relay (most models) you'll find the starter relay at the other end. There should be a fuse in the relay or in a panel on the atv. Same type square standard sized boxed fuses car use. Best place to start. If you comment or answer with your year, make, model and engine size I can provide a better answer.

**FYI - that's a pretty standard starter relay. That's for a Yamaha Bear Tracker - two fuses - one is the main and the other is a spare that you can pull out and use. When the fuse blows no power. - With your lights - they will still work if attached directly to battery. Relay won't if fuse is blown.

29, 30 & 31 are the starter relay for the model this diagram goes to. Usually the relay is going to be close to the battery, by the way.

My 1997 kawasaki 400 pirarie will not show any sign of life when i turn the key like No lights to neatrul light nothing only thing that will work is my winch any suggestions?


Look for a fuse where the postive cable comes from the battery going to the starter relay - this fuse (like a 10 or 15 amp box fuse) allows all the electrical to basically go to the bike. When it blows - no ignition, but the bike will usually pull start. - Your winch is probably still working because usually - it's hooked up straight to your battery. if that's not it - let me know and I can help you troubleshoot it - all the best

I have a 1999 Suzuki quadrunner 4x4 I bought it under impression it just needed a carb rebuild and it had been siting three years guy told me he tiped it over and after that it back fired and cut out when...


It sounds like you know a lot about cars, let's start from the obvious, have you checked your grounds? If it rolled those can be exposed and touching something they shouldn't.

Atv trouble shooting


Whoops, can you tell me why you changed the fuse and what happened before that, and are you sure it wad a 30 amp that's awfully high, what was the fuse for on the machine, and sometimes it will blow fuses if they are too high not good, and plus doo you have any accessories you have added to the machine? Might be battery not grounded, like if it gets wet will blow the fuses, and an overload of amperage more details unless this helps ya
