I just picked up a 2004 Yamoto 70 quad in a trade (for something I was hoping to get $50 for)

I am told that this is a knock off honda?...

The guy I got it from said, that he thinks the ignition coil is bad... I think the problem is much simpler & that it's just not plugged in. The attached picture is of under the seat where the battery goes.

The red and green obviously land on the battery terminals, but where does that square plug go? I can not find any open connectors...

Could there be a small harness that's missing that also lands on the battery, and connects to this plug?

Any help is appreciated.

I've been doing a lot of research as quads are kind of foreign to me. I think you are right about the kill switch. Can anyone confirm this?

Also the piece the guy was calling an ignition coil, is just a solenoid. I will test it tonight and hopefully get this thing fire up this weekend.

That hand drawn one is nice. I'm pretty sure that clears it up.

Two more questions...

To test this solenoid do I just check for continuity between the two main post with the ignition on and the switch in the run position?

&

Does anyone have tips for tuning up a quad that has set for a couple years?

Thanks.

yes & dump the old gas, new gas with double recommended amount of seafoam, new plug and if everything starts and runs well, ride it. if hard to start could be valve lash off a bit and/or dirty carb (seafoam should take care of that, remove bowl on carb and if its really bad, soak the carb in some cleaner first)

and of course the fluids, oil and front and rear diffs...

Ok, so... I put it together, put in about a gallon of gas, added some sea foam, and jumped it with a spare deep cycle battery (the battery in it needs replaced), and it fired up. It ran for about 10 seconds & stalled out. When I went to restart my battery was dead.

I guess that's good enough for tonight. I will get a new battery soon.

Thanks for the help. I really appreciate it.
