4x4 problems will not go into 4wd

[peterline_158]

Hi i have an 05 brute force 750.
It willnt go into 4wd. when i turn the switch to 4wd the indicator just stays at 2wd and the actuator doesnt move or make noise? i tryed a buddies controler and that didnt work. i put mine is his bike and mines good. manuel say dead controler but its not that. i have not done the BUSS fix yet could this be my problem? side note, i was just have tones of issues with the bike backfireing and missing could these be linked?
what should i be checking???

thanks for all your help!

Fix the BUSS first it will cause all kinds of problems.

The buss connector is a must for 05 and 06, but one more spot to check is the fuse, and fuse box itself they are known to corrode underneath. There is a connector on the bottom of the box that gos bad.

i have the same exact problem with the exact bike. besides ive already done my buss fix and my fuse is fine?!?!? i really need to get this fixed but i dont want to pay alot of money to take it to the dealer to get it worked on

peterline if you know your buss is working then that has nothing to do with 4x4 but if your buss is broke and need fixing thats your problem

FINALLY fixed my 4x4 probelm a while back i took the 10w fuse out for the engine brakng put it back in worked right off the bat!

Yah the fuse itself usually fine, its the connection the fuse plugs into and the connector under that too, on the bottom of the fuse box. So pull the one 10mm bolt off and lift the box up to check that too. Oh and dielectric grease is your friend use it on all of the electrical plugs on the bike. I do this on all of my wheelers including new the ones.

I got mine to work. My buss was already fixed when I checked it. What I did was jacked it up and put it into 4wd started to run the bike at about 4 km hr. Then I taped the front actuator with the end of the screw driver abot the tenth time it clicked in and started to work. Now it is going in and out just fine. Hope this helps someone out.

Thanks for all your ideas

Mine wasnt switching, it was the speed sensor.

Yah the speed sen will do it too. Speaking of the wheeler needs do be rolling around 1mph or so but less then 12mph or so, to switch back in forth. its some safety thing they have.
