My 68 442 4 speed as the following issue: with the key in the "on" position the "reverse" lights stay on permanently. How do I fix the situation? Is there a "connection" problem? Any help would be great.

 

There is an adjustment on the reverse light switch mounted to the trans. A small metal rod is attached to the shift link and it works the switch.

 

Trans bkp lites switch link may have fallen off, or perhaps your shift fork lever is not coming all the way out of R when using other gears.

In order for Reverse Lights to be on I believe the lights have to be on, and the switch controlled by the lever on the trans has to be in the ON position. Not sure on the lights switch part- check your service manual wiring diagram.

 

My 67 is like he mentioned, ignition switch on there will be power to reverse lights. I am not sure if this is correct but it is the way mine works with factory harness.

 

With the ignition on the "OFF" position if I turn the lights on the "Reverse light" don't come on. It's only with the ignition in the "ON" position that the "Reverse lights" stay on all the time.

 

Chris? If that was the case he'd have to turn on his lights every time he put the car in R, and that's not the way it was designed.

I'd suggest the problem is in the neutral start and backup switch position.

 

Sounds like your back up light switch is screwed up -
Switch broken / jammed
Switch fell off and dangling
Switch misadjusted / linkage problem
Short somewhere in wiring (much less likely).

No big deal. Go look at your switch and see if it's being properly moved by the shift mechanism.

in 1968, a factory 4spd has a separate backup light switch mounted right on the trans. As noted, the problem is either in the adjustment of this switch or the link from the reverse lever on the trans to the switch itself. And yes, this circuit is powered by the ignition switch, not the headlight switch.
