Forgive me is this has been asked a million times before. I have a 90 SJ. The white and black wires are disconnected near the carbs. As of now, the ski starts. The idle is turned down so it cant idle. If I turn the idle up, it will idle but not shut off by pressing the red button or by pulling the lanyard. Now when I reconnect the black/white wires, the thing will not start. Im guessing the problem lies inside the black box? And should I bother to fix this, or leave it as is?
