Electrical Reverse Light Switch Question

[MJkid67]

This is my second post as I am working through some minor issues on the new to me 1985 CJ7 .

I'm having trouble with getting the reverse lights working. I removed the reverse light switch from the driver's side of the T-5 Transmission and it did not pass the continuity test when I pressed the ball side of the switch in. So, I purchased a new one from Crown, tested it for continuity before I installed it, and after it was installed (about 2 weeks ago) and it had continuity.

So I had some time this past weekend and still couldn't get the reverse lights working. I backtracked and tested the new switch with the Transmission in reverse and now I don't have continuity (between the two posts). I tried loosening it a little and then tightening it a bit more than it was with no luck. I then took it out and it tests fine outside of the truck.

I'm stumped! Any ideas or tricks?

Thanks

Sounds like maybe it is a NC switch and when you install it, it is making the switch during install and opening. So, if there is something in the installation that is keeping it pressed in, it will stay in that state. Is it doing this no matter what gear it's in?

Sawjaws, I wasn't aware that NC and a NO switches were available. I know that when the ball is depressed I have continuity across the two posts.

I will check later today if the state changes in other gears. Thanks.

Fingers crossed!. I did a little online research last night too and it is possible to have the switch seated too far in as well. Something thing to be conscious of as well. Good luck!
