I have a rebuilt 727 getting ready to install.How can you check the 3 prong neutral safety switch.I have a meter to ohm it with but dont know what pins should have continuity when in park or neutral
Are you saying if it is in park or neutral i should read continuity on middle pin to the case of the trans^^ and the center pin is grounded in park or neutral ^^ Outer pins are reverse lamps
I check from center pin of nss with the lever in park or neutral there is no continuity between the pin and the case.The electrical connector is unplugged from the nssExactly. In reverse, the two outer pins should have continuity to each other
That is what i am afraid of.So you should show continuity between the case and center pin when in park or neutral.I do not have that.It does show continuity between the 2 outside pins when in reverse which it should.Just trying to make sure i am checking it correctly.Need to sort this out before putting the trans inJust went through this kind of. Got a new trans and it came with a three pin switch also. Long story short they put in the wrong rooster tail in the trans. Just my .02
I checked to the body of the sensor to middle prong and moved it to rev and park no continuity .I am going to take it out and replace it with a new one when i get home the pan is on the trans just had it all redone trying to make sure this switch is working before i put it inWhen you are checking the switch, are you pushing in the contact ball on the switch at the same time? If I remember correctly, it produces a ground from the switch body to the center prong.
