Last week I drove 17 hours hauling my 2013 Kymco UXV 500i to the western high plains in Colorado and thought I had all things ready to roll. First day, my bike drove perfectly. Got back to camp after going through rugged sage tundra off road and my Kymco performed perfectly. Now looking back I was very lucky after returning back to camp. This could have happened in off road in back country!
Later at camp I decided to restart my Kymco and I would get power and the EFI pump would work lights came on but the starter would not get the charge from the solenoid so the engine would not turn over. There was no clicking sound from the starter. Man, was I disappointed but very lucky. So here I am my Kymco is down but I was not out. I went to a remote Arctic Cat shop and purchased a basic lawnmower solenoid and connected the green fuse block think I'd have it back working. Nope, nada, the machine would not work. Turn the key, EFI worked to prime the engine, lights come on and starter would not get any juice to start the engine.
Let me step back a bit. During my first day after having starting issues I discovered the battery positive post during my ride literally broke off and thinking I could have shorted out a sensor somewhere. I replaced the battery and reconnected things per my comments above. The primary red wire to the solenoid showed power was doing into the solenoid but no power was coming out of the solenoid to the ignition key or other possible key areas like the sensor for the starter and shifter to recognize the gear was in neutral. So what I did for the week was by pass the solenoid and jumped the two primary post with my needle nose pliers. I turned the ignition key jumped the solenoid posts with my needle nose pliers and the engine would start and run perfectly. Each time I stopped I would jump the solenoid to start the motor.
I am hoping someone here can help me trace where each sensor is located so the solenoid can start my Kymco. Any other suggestions great appreciated. Where do I start?
1. The ignition wire sensor to check?
2. Is there a shifter sensor that requires the shifter to acknowledge the sensor is in neutral?
3. Is there a brake pedal sensor that that could be the issue?
4. Any other suggestions?
I have ordered a new Kymco Solenoid and will be here in the next week.
Note: the engine is so strong logging over 250 miles in back country but I had to jump start the solenoid to do this.
I hope someone here can help me what areas to check so I can start my Kymco UVX 500i with my ignition key.

Go back to the original solenoid, there should be a built in fuse(s) and a wire gang plug. Check the fuse, if good then Wiggle the wire gang plug with the key turned to the start position. See what happens

Trailer biking is hard on machines.

You do know on that machine you have to push on the brake pretty hard before the starter works, right? Have you checked out that end yet?
By the way, I am a little confused about UXV500i on one hand and "bike" on the other. Could you clear that up for me, please?

Absolutely I understand the brake has to be pressed to start the bike/UTV/UXV 500i. Bike is a common term used for ATV/UTV/Side X Side machines. Also the shifter has to be in NEUTRAL too besides pressing in the brake. Is there is a sensor with the brake? If so where is it located? I guess I need to check wire harness plugs. So when we are using the term sensor are we talking about the plug connectors at the end of each wire harness?
I just purchased a new OEM solenoid to start over. All fuses are good too. In the desert I had limited Kymco shop options and I am no mechanic. In a town with one diner there were not many Kymco dealers to locate. :)
Electricity is a process of elimination and more then likely a simple fix. However, I need help to start. Oh, I did remove the green plug from the solenoid cleaned contacts, checked the 30amp fuse and wiggled the connectors. I am hoping someone with KYMCO electrical wire harness knowledge and experience can help me eliminate what I anticipate may be many steps to find where the electrical issue that is causing my issues.

It's a start point. Maybe there was to much corrosion. Will do thank you.

I don't follow. What is your point. I have a 16' dual axle trailer that I pulled my UVX 500i. Not trying to be smart. I am trying to understand the cause and effect of your comment.

Everyone, thank you very much for your comments. I really do appreciate your feedback.

If yours is scooter---I believe they were designed to be ridden.

UXV if I'm not wrong is a side x side and not street legal so you have to trailer to your destination for off road.

Yes I have to trailer my Side X Side. I'm not sure how this relates to my issue. Can you contribute anything to help me resolve my issues?

After reading in the manual I do not think you have to push on the brake to turn on the motor as long as it's in Neutral. I re-read the manual but not sure that is correct. If you have confirmation please cite that in the manual. Thank you for your followup.

I was trying to explain to John who thought this was a scooter that trailering is the only option to get to where you need to use it. I would make sure all the ground wires have a good connections as well.

I park mine in, ah...PARK! When I start it in PARK the brake pedal must be pushed for starter to engage. Have not tried to start in neutral but will soon! I honestly do not know where the switch is on the brake pedal! Could be a plunger switch or brake line pressure. I will look....
-
Thank you all. I really appreciate everyones support. Damn, once started the Kymco rang great! Just like to do it with the ignition key. 8)
There is nothing more vexing then electricity and he spaghetti harness.
Checking the ground wires is a good idea. Some shorted out I suspect after inspecting things my battery post actually cracked apart upon inspection. I guess using a line one tester for all the wire harnesses on my Kymco is he logical next steps.

Replaced solenoid and back up running.

Good to hear! By the way, seeing this post reminded me I actually tested mine awhile back like I said I would. On our 2014 UXV500i the brake must be pushed in any gear for starter to work.

Duly noted.
Next thing I just can't figure out is why my gas tank floater will not display on my console cluster. I remove it from the gas tank the fuel gauge will appear. It's in the wire on the floater tube. Some how it's shorting out when I submerge. Is there a way to insulate that wire. There does look to be a some slits n the wire where the float tube rises. I can remove this arm but it's attached to a sensor on the EFI pump.
