2007 Rancher 420 4x4 no start condition

Hello all, I'm new to the forum and hoping for some advice. Several weeks ago my 2007 rancher 420 manual shift atv wouldn't start, just the selenoid clicking. Then it started for a few weeks with no issue, then started the same thing. A no start issue and the selenoid just clicking

I have replaced the battery, the selenoid, the starter, cleaned all cables from all terminals, I have continuity from the start button, full voltage to the selenoid and to the starter. I can start the atv by jumping straight from an external battery directly to the starter. It will fire up with no hesitation.

Now when I hit the start button the selenoid won't even click, absolutely nothing. But I can still fire up the atv by going straight power to the starter. I'm completely stumped !!!!. BTW I tested my original starter and it really was bad. So it seems that the original no start issue really was a locked up starter. Any advice greatly appreciated.

Thanks for the advice guys. The selenoid I put on is cheap China junk. I just ordered an OEM selenoid. Once it arrives I'll give an update, probably in about a week.
Ok guys I'm back. I installed an OEM selenoid and replaced all cables from the battery and selenoid to the starter. Still doing the same thing, just clicking. I'm wondering now if it's possible for my start button / kill switch assembly to be bad. I have continuity through the wires, but when I hit the start button I notice that the fuel injectors kick out when the selenoid starts clicking. It's like there's not enough amps / voltage to activate the selenoid and keep the injectors running. It seems like it needs more power to do all the tasks it needs to do. Hopefully this makes sense because I'm definitely in over my head now and struggling to explain it.
The atv still fired up with no hesitating when going straight from an external battery to the starter.
Ok guys. Here’s what all I’ve replaced, with OEM parts. Battery, selenoid, starter, ground and positive cable, and start/kill switch. It’s still doing the same thing. The solenoid just clicks very fast repetitively and the injectors kick out. But I can still start it by jumping straight to the starter with an external battery. It fires up immediately with no hesitation. Thanks for all of your advice so far. I know this the process of elimination. So hopefully we nail down the problem soon.
Thanks for the diagram and the link to the new forum shadetree. I’m gonna dig back into this thing next week (after my frustration dies down a little) and I’ll let you all know the results.
OK guys this is my update, and it turns out the problem was very simple And you all told me what it was in the very beginning. Turns out that I had my ground wire connected wrong to my starter. If I checked it once I had checked it 100 times. I just missed it every time. Thank you all for your help on this and as of now my four wheeler is running and I can use it during this cold Indiana winter.
