RE: 280se 4.5 won't start

I could be the Ignition switch itself or the safety neutral switch,on some models it's on the transmission. Be careful because your bypassing the safety switch and if the car is in gear it will take off on you!!very dangerous.You need a test light and a helper to search out the problem,but because it's an "open" in the wiring it will be easy to find.Don't cut any wires to do testing,use a short piece of wire to jump out the safety switch,on mine it had 4 wires,2 for the starter and 2 for the reverse lights.
