I have a suzuki LT80 that wont start. There is a clicking noise, but it doesn't come from the starter, it comes from the relay switch.
It's kind of a pain because the quad is at our property in the middle of nowhere with no phone or wifi , so if I just buy a knew relay and that isn't it, I have to wait for something else.
I've already bought a knew battery

 

Have you pressed the re-set button under the rear wheelarch. Early LT80s didn't have it, but it is there to blow, like a house trip, if the starter gets overloaded. Why did it trip? Can be just one of those things, or the engine locked due to you leaving it on PRIME and fuel filling the sump & cylinder. If it isn't the overload button, I go for the test lamp method. 12v lamp connected between good earth on engine and starter live post. Press start button, solenoid clicks and lamp doesn't light, faulty solenoid or overload button, or bad earth, if lamp does light, faulty starter. You can narrow it to either solenoid or overload unit by testing with test lamp lead on wire between them.
