Definately!! I haven't pulled the switch off yet hopefully maybe later today. I did however when I got home tonight move the gear selector to it's sweet spot just to make sure the lights would come on and they did. But then I did it a second time and I couldn't get them to come back on??

Crazedfox,
I checked power on the white/purple wire and have 12V on both sides of the grey plug BUT as soon as it goes into reverse I loose power. The rest of the gears I also have 12V, it's just reverse that I don't. Is that normal?? This is weird......

Agh,
__the more work & age these old trucks see,
the more personality they acquire.
Onward we march;
it sounds like a short.
Are the reverse bulbs new?
What shape is your sockets, & grounds?
Take care of these, then try resetting the NSS again.
I know it sounds like a lot.
But we got to make shure that the
NSS itself, is not shorting out.
Good, luck.

My bulbs are new as well as the sockets. I even wire wheeled the ground terminals that screw into the bed. How can I tell it the NSS is shorting out?? Tonight at work I double checked the alignment and moved the gear selector very slow throughout the whole motion going from P to 1. The lights didn't even blink. I still have contunuity between the white/purple and the black/red wires for the switch. I just can't figure out why I have voltage in all gears except reverse???

I wonder if it could be the NSS?? This is the second one I've put on and the first one the lights worked for about two weeks. I bought it from Advanced Auto and I think Bosche makes the switch. It has a year warranty but they threw a fit last time I had them warranty it out.
I also tapped on it to get it to back on the shaft but they were not working before then anyway.
I'm confused??

Well,
__this one is becoming a real challenge...
Let's try taking the switch off the tranz's shifter shaft.
(Try to remove it with the trans in park, so you know where park is.)
Then with the wires still connected, move the switch to find the reverse lights this way.
If it still refuses to light, remove the switch & test it for continuity.
(With the white W/purple stripe wire on 1 probe & the black W/red stripe with other probe.)
Should your switch pass. Were going to be looking at short somewhere in the system.
__________________________________________________ ______________
P.S.
while you have the switch out, test the reverse lights & system by:
Taking a jumper wire & connecting-or-touching the two (white W/purple wire & black W/red stripe) wires.
Remember the white W/purple wire is the live wire.
DO NOT APPLY VOLTAGE TO THE RED w/ BLUE WIRES!
These are your neutral shifter wires.
This is a real qwick way to eliminate any guess work or doubt in the rest of the reverse lighting system.
Outside the NSS itself of course.

Well the switch test ok but I was not able to make the reverse lights come on with a jumper. I thought for sure they would.... Now I really don't know where to go from here???I'm thinking a bad ground somewhere because I've check the reverse light circut in steps. What I have found out is I took the light out of the socket and went from the side terminal in the socket to ground and both light were open. So I believe that means a bad ground somewhere. Is that right.
But I also took a jumper and went from the side terminal in the light socket all the way to the neg. side of the battery and still wouldn't light???

Ok,
__take the rear lead jumper that you used for the NEG. side of your test.
Connect it tightly to the bare wire of your ground for the rear lights.
Then do your jumper test up front again.
(The side marker light has 2 connections to the harness. Both could have let you down. You will eleminating this prob. with the NEG. rear lead jumper.)

Sigh,
__it seems that I don't have the vocabulary to pass my direction of dictation properly.
Let me try again,
Take your rear lead jumper that you made for the ground test of your rear lights.
(the test you did with rear side marker.)
Connect it tightly to a bare wire on the ground wire for main bed wire harness.
(Right before the grounding terminal behind the tail-light is good.)
Make sure that the rear lead jumper is connected to the battery's Neg.(ground) post really good'n'tight.
__________________________________________________ __________________________________________
Then... go up-front & try your jumper wire test with the WHITE W/PURPLE stripe & the BLACK W/RED stripe wires again.
P.S.
Make sure that the NSS is not connected. & you have power at the WHITE W/PURPLE stripe wire during the test.
