we have a p650 4x4 that wont go into to 4wd i took the actuator off and the motor isnt
frozen put a tester on the switch and it opens and closes does anyone know what else
to check for?? it dosent make any noise when you hit the switch, also the belt tensioner
used to do it thing when you turned the key on and off that no longer makes sounds either???

 

It's a good chance that the two items are related. The engine brake actuator is tied into the 2wd/4wd actuator.

Are the 2wd & 4wd lights flashing when you turn on the key. If so what is the interval between the flashes?
Is the speedo reading movement?

If you need more info maybe I could fax you the required pages from the service manual.

 

Check the fuse under the seat for the engine brake, it controls the 4x4 also........

 

If the lights are not giving you any signs and the KEBC is not working, it should be the fuse under the seat. If not, check back and we'll help some more.

 

My belt tensioner motor went bad and my p650 wouldn't go into 4x4. Like you said, the motor made none of the normal noises at turn on or shut down. This could be the problem. Changed the motor and it works like new.

 

when you turn the key on it just says 2wd it dosent change when you hit the button
im thinking the belt tensioner went out about the same time its not my bike
if the tensioner doesent make the engaging sound does that mean its out??
and could this be the problem?

 

where is the cheapest place to get kawi parts?

 

I had the dealer replace the tensioner motor under warrenty, didn't cost me a dime.

 

You have checked the fuses right? Anyway, here is the test for checking the braking actuator. Use a hand tester and check these resistances on the actuator plugin. Red-Black, 3-15 ohms. Orange-Blue, 3.5-6.5 kohms. Yellow-Blue, 630-5,330 ohms. Let me know your results.

The manual lists 5 reasons for the brake actuator not to be operating properly. 1) actuator failure (test above), 2) actuator controller power supply (check to see if close to battery voltage at controller), 3) speed sensor failure (might be worth checking, some guys have had problems), 4) F/R detecting sensor failure (1.2-1.6 kohms resistance) & 5) actuator controller failure (test controller output voltage, 5-12 volts to braking actuator).

I still think the two problems are related. Too big of a coincidence not to be.

Let me know if you need more info.
