No neutral light 300ex

I have a 2003 300ex. I bought from a guy who put after market handle bars on it and when I bought it it had no headlight, neutral, or reverse light hooked up. I put the headlight back on (works fine). I then replaced the neutral and reverse lights but neither one work. I do not know much about the wiring and cant figure out why they dont work. The quad will not start in reverse, so I assume that part is still hooked up. Any ideas what he could have done? Checked both lights also and they work, so its not the bulbs.

Welcome to the forums. I agree with Deep and make sure the wires are plugged into the neutral and reverse switches.

Most 4-wheeler problems are caused by a loose nut connecting the handlebars and the seat!!

You only need two tools in life -- WD-40 and duct tape. If it doesn't move and should, use the WD-40. If it shouldn't move and does, use the duct tape.

Everything appears to be in the right place and hooked up. The reverse and neutral switches are hooked up with good clean connection. Could it be a bad reverse inhibitor?? Everything works normal (wont start in reverse, wont start in gear w/out clutch pulled in and starts fine in neutral). The only thing not working right are the reverse and neutral lights??? I have power to both of them threw the black wire, its like its not grounding when its in neutral or reverse. And it will not start with neutral or reverse switches unplugged(I tried it when I checked the connections), so I assume they are working ok.

Ok -- Remove the wire from the neutral switch and ground that wire to the frame, the neutral light should be on (key switch on). Grounding the wire is just a test remove it after. Then do the same for the reverse switch. Also when the bike is in neutral you can check the switch --- with your meter from the switch to the frame you should get continuity. Do the same for the reverse switch.
Are both wire connected to each light -- should be 2 wires on each light, you have said you have power on the black wire, follow the wire from the other side of the light it should be connected all the way to the reverse inhibitor ( both light end up there).

Here is what I have: The neutral switch grounds when its in neutral, and looses its ground in gear. The reverse switch is grounded and looses its ground when in reverse, and the neutral switch stays grounded while in reverse? This stays the same all the way to the reverse inhibitor, but neither light works?? They are both hooked up to the correct wires. I am totally lost. I took the wire off of neutral and reverse switches and grounded them to a good ground, one at a time, and no lights!! My last guess is a bad reverse inhibitor box.
