Check my thinking on a no cranking problem

Location

Working on our 1100 SXR. About every third time you hit the start button you just get a click and it getting worse. Checked the easy stuff first, start stop switch with an ohm meter and works perfect. It's clean inside and connector checks out fine. Both the battery, cables and all connections check out good. When it does crank, it spins the engine over very easily and fast. With a volt meter between the starter terminal and a ground, when you hit the start button, if you get a click, you have no voltage. So this leads me to the starter solenoid is bad.

The ebox is beside the fuel tank, so there's no way to get it out or apart without moving the tank. To move the tank on our ski you have to pull the engine.
Before I pull it, did I miss anything?

Did you try a new battery? I know that seems too easy, but I've had that scenario a couple times. Once it was the solenoid, once it was a battery that i would have sworn on my life was a perfectly fine battery, but it wasn't.

Your bendix could also be binding. The way to test the selenoid would be when it clicks and doesn't start then you would jump the selenoid leads or jump straight from the battery to the starter. If it turns the motor over, then it's the selenoid. If it doesn't it's the starter or bendix.
 
If the solenoid clicks, 99.9% of the time it works. On kawi anyway. Yami is another story. If the starter has a dead spot on the armature, it wont spin if it stops there. I'd bet money it's the starter taking a dump. If you bypass the solenoid by zapping across the terminals and you can get it to not crank, it's the starter

If you’re having intermittent voltage at the starter post obviously the issue would be the solenoid (or something upstream which it sounds like you’ve ruled out).
If you even have intermittent voltage ONCE at that starter post I would immediately suspect the NOID!!!! I’d also try a different battery just to be safe.

I suppose I could have a couple issues going on, but If I have no voltage at the starter when the start button is pressed and the solenoid just clicks, I don’t see how it could be the starter.

I need to check the battery voltage while it’s actually cranking.
 
1100 sxr...so you're using a triple 1100 2-stroke from a zx-i or something like that yeah? Check the fuse block, it should be a little round block? They can be taken apart and the area hidden under the fuse slots most likely is corroded up enough to insulate the power throughput. I spent about 10 hours straight chasing similar issues on an old Kawi couch only to find it was the fuse block. I cleaned up all the contact and metal paths under the fuses, then coated them in dielectric grease, that was the correction it needed.

I agree with your thought process it's probably the starter telay.

I also assume this motor is probably crammed in there and no fun to remove and reinstall so I wouldn't put it back in without a new oem relay and a closely inspected starter that I'm really confident is good.
