I am having the 2wd and 4wd drive light flash for the engine brake actuator after driving the bike for 20 min. I recently had a problem with the wiring harness being corroded, I have since then had that fixed. When the light is flashing and the bike is running if you pull the fuse and put it back in nothing happens. If you do this while the bike is off it resets. If you unplug the control box while the bike is running it will reset. If it is acting up and you shut the bike off and wait 10 seconds and turn the ingintion on it will not reset. I have tested the resistance in the actuator and it all seems to check out. Any ideas? is it the actuator or the contol box. Any other test I can do to check this problem out?
