So I'm in the middle of my rebuid project, I have a SM465 transmission. I thought I knew what I had, but I guess I'm wrong, on my trans there is two connectors, 1 one wire(top of case angled 45degrees to driver side), 1 a two-spade terminal (top of case, lower than the other, pointed straight sideways to driver). My first guess is ok, on'e s neutral safety switch and the other is backup. One is definatly the reverse light switch the two-spade lower one pointed directly to the drivers side. Hooking the ohm meter to it, it goes from infinite to 0 when I put it in reverse. Ok, great. THe other I cannot seem to make it do anything in neutral or anything else. I removed it and tried to actuate the little ball while it was on a meter, nothing. I tried running power though it, ohm testing it..nothing makes it do anything. So either my switch is bad, or I'm not running the right test. Anyone know what this switch is supposed to be for? As I said, before I dissabemble the truck, I'm almost sure my truck had no neutral switch, well it may have been there, but it sure wasn't hooked to anything because I'm sure I could start my struck in any gear, I remember running out of gas 30 yards from a gas pump once and cycling the starter while in gear to get there... So what is this switch?
