I am trying to replace my ignition switch and keep it looking like the original but case does not list a part # for it. I found a switch that looks similar but has more contacts. The exsisting switch has 3 terminals new switch has 5 labeled ( I ignition to coil, B power from battery off starter post, F gen post on regulator, S switch to starter solenoid, and L lights and fuel gauge) Is this switch usable as a substitute and how would it be wired? the replacement was for a JD 1010 part #AR26528 I connected I B S but that leaves the F terminal open. It will turn over slowly or some times just click. We are using a new battery and it was starting fine before. Should I go back and get a generic 3 pole switch ? Wanted to keep it looking like original. Thanks for your help. Chuck
