06 Rancher headlights and starter wont work without back brake and LF brake lever

I'm new- I dont know what to do! (feel like Joe Dirt working in the oil field!)

06 Rancher headlights and starter wont work without back brake and LF brake lever.

Battery and starter solinoid were recently replaced to try and fix problem. I unplugged the rear brake switch and now I can not get the head lights or starter button to work. If i plug it back in and push it and the RF lever the headlights come on (if switched on) and engine will start with button.

Any ideas?

Thanks.

I could live with the starter that way. The main problem is
That you would have to push and pull 2 brake leavers to have headlights!

try tracing the light switch wires down...and seeing if you have a worn spot making a short ?..you should not have to work the brake levers just to get the headlights to work !!!..i'm following you now..nooo..this is not a safety feature..this is a elec issue problem.

1970: It sounds like your brake switch, or line is making a ground which is allowing those devices to operate. If that is so, follow the brake cable all the way and see if there are any worn wires along the way. If that isn't it, then it could be that when you pull on the brake cable you are also pulling a wire together somewhere which completes a circuit so that those devices will operate. Again, look along the entire brake cable to see if you have any worn or broken wires. And last, it is very possible that you have a bad ground/chassis connection somewhere. If you have a short circuit (where a positive wire is shorted to the chassis), then you'd be blowing fuses, and you're not doing that. Therefore, it is most likely that you have a bad ground somewhere, and that ground is common to all the devices you listed. Additionally, when you apply the brake, that bad 'ground' is turned into a good 'ground'. Look for loose parts and connections, and bad chassis grounds. And, of course, look for a broken or worn wire along the length of your brake cable. Good luck. This will take some detective work, but I think this information will help you.

X2, this ↑↑↑↑↑ has to be what's happening.

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.

1970, did you find the problem? My 06 Rancher 350 started doing EXACTLY the same thing today and the electric shift does not work either.
