Have a '94 400L 4x4 with many issues. None of the OEM electrical systems will work. Someone added an additional start button, bypassing the original. This works. Sort of. You have to put the original slide button on the handle bar in the on position, and turn the start switch to the on position, and then the new start button works. Turn either of the original swithes off, and the motor shuts down. Nothing else works, no lights, no dash lights, no 4x4 button. I have replaced the wiring harness and cdi with no results. It runs fine, just no electrical anything. I don't really need the lights much, it's just frustrating not to be able to figure it out.
