Hi Guys,
Ok I am stuck, my back up lights (reverse) don't work, I know the 2 outside pins are suppose to short together when in reverse to turn the lights on, with the car in reverse the switch does not close (I have been under there with my meter) So the trans is an early 1970s non lock up. It has been rebuilt and the NSS was replace with new.
The car cranks over in Neutral and Park and in any other gear will not crank.
Now there is something odd going on the 3 pins on the old switch are slightly bigger diameter. Also there appears to be 2 different NSS, I will call them short hex and long hex.
See attached photos. What's the difference in the NSS?
If I short out the loom 2 outside pins the back up lights work. The back up lights have never worked on the car since I have owned it, even when it had the old 904 lock up trans, the switch in the old trans looked quite new when I replaced it, I wonder if its been replaced with the wrong one?
Long Hex
Short Hex
Can anyone shed any light what is going on, are the parts of the switches that go into the gear boxes different lengths?
My current set up
this is my old switch I think from my lockup trans. It seems to test ok but the reverse lights did not work with it, hence it was replaced.
