1970 Headlight Opening Problems
Hello,
Need some help from anyone who has experience with these headlights on a 1970.
One of my headlights will not lock all of the way open. This causes it to bounce and not trigger the headlamp warning switch. I can lock it by had but it takes a fair amount of effort to both do this and undo this. The vacuum pots operate fine, something just seems out of adjustment at that end of the lever stroke.
Is there and adjustment on these headlight mechs for this lock process?
Thanks

WIth the light open, disconnect and try turning the push rod from the actuator so it's longer and pushes the connecting link further forward. Once it's in the correct position reinstall the cotter pin.

I disconnected the actuator and it is still very hard to lock and un-lock the assembly. Is the up-stop located on the outer part of the swing arm or is it somewhere else? I feel what seems to be a threaded pad up there. I know the downstop is a bolt right behind the electric switch assembly for the warning light.
Thanks

If your talking about the screw in the locking mech. thats a limit screw that adjusts the height of the bucket in the down position.The one I think might be your problem is on the end of the outside arm towards the fender.Look up inside its a seperate arm.But make sure as GD70 said you have enough stroke from the actuator.Be careful when trying to adjust the screw will break easily.Should have a locknut on it.
