hello, my 4x4 does not engage the 2 and 4wd indicator lights flash back and forth i put my electronic control unit on another 750 and it worked fine can somebody give me a place to start. thanks

 

If you think your controller is OK, then the problem could be the 2/4WD engagement actuator on your front gear box. Apply 12VDC directly to the actuator motor and see if it turns. Also, count the cycle time of the flashing. When 2/WD light is flashing - 2WD>4WD>2WD, how long does it take for 2WD light to flash again?
1 sec - 2/4WD actuator is bad.
2 sec - EB actuator is bad
4 sec - controller or others.

 

4wd engages and disengages like its suppost to but light still flashes back and forth. also broke a tie rod end and wanted to know if a gizzly 700fi tie rod end would fit my 750 brute force

 

If 2/4WD and Engine Brake systems work fine but the light is still flashing, then it is just an electronic glitch which can be easily reset either by removing one of the battery terminals (+ or -) or replugging the Controller (single connector black box) connector under the seat. Don't know about using Yammy's tie rod but you can measure and compare.

 

its you ebg motor just take the freakin thing out its on the top of your cvt cover .there about 300 new .i mean just remove the forks on the inside of the cover cheap fix and you will never miss it

 

But the original poster has 4wd engagement problem, not the engine brake. Removing the EBC motor from the quad would not fix his 4WD problem.

 

hello i have the same problem with my bike but it does go in and out of 4wd 2wd .when the light starts flashing i just stop put it in neutral andturn the power off for a second and it stops flashing it happens 2or3 times in a 65 to80 km ride

 

bad750,
No, you don't have the same problem as the original poster does. His does NOT egnage to 4WD. Yours does you say. Yes, you have the same 2/4WD flashing light on the meter but it would be flashing at different interval (cycle time) meaning different problem.
Try this. Lift up the seat and look for a small black plastic covered fuse box. Open it and you will see somehting like EBC fuse 10-amp. Take the fuse out and twist the blades just a bit so it would give a tighter fit. Then apply white lithium or di-electric grease at the contact area. See if this would cure the problem. If not, you may need a new controller.
