Wasn't there a batch of headlight switches made that had the rocker
installed upside down giving this exact phenomenon?

Thanks for the many great tips :) 
I run out to the garage hope I have made ??a "fool" of me and forgot to
put the ignition in the right position. but no, no change. buckets still
up ..
what is strange is that when the switch is on the left all the lights
on. and buckets are up.
switch in the center just park lights,
switch on the right all the lights off. still buckets up .. is it
possible I have swapped two wires when I replaced the fuse box?? 
so in some way I have managed to get the switch works wrong way
this was not easy:(

Some ideas??

Freddy

Now I need some good advice from you guys :)


>>>You'll get some from me, although I can't guarantee how good it will
be!

from pantera electronics :) so far, so good.


>>>Jon makes beautiful stuff!


>but I have one problem. headlight buckets will not shut down:( ??if I
take
them down manually, they come up when I turn on the lights.


>>>Okay, that sounds right at least?


>I can not remember but it also appears as if the light switches works
the
opposite. since I can not remember properly which way to turn the lights
on
and which way the switch should be when they are switched off, 


>>>When the switch is to the left, the buckets should be down, lights
off. In the center position, the buckets should be down, side and
taillights on, headlights off. When the switch is to the right, buckets
are up and all lights are on.

When you move the switch from the right, back to the center, headlights
turn off and buckets come down. All the way to the left, all remaining
lights turn off.


>now the
lights possibly are on when the switch say they are off 


>>>You should be able to see the lights glowing inside the fenders, if
they are on when the buckets are down. However, all the outside lights
should also be on at the same time.


>and no lights when
switch is on.


>>>No lights at all? Or just no headlights, but all other lights are on?

Don't forget that the headlight switch works all the lamps, whether the
ignition key is on or off, but the headlight buckets will only move up
and down with the key in the 'run' position. That is actually helpful
for troubleshooting lighting problems, because you can raise the buckets
with the key on, then turn the key off, and turn the light switch on and
off and test the various lights without the buckets moving up and down.

But if you don't remember that the key has to be on to move the buckets,
it could drive you crazy trying to figure out why the lights turn on but
the buckets don't move. :>)


>all help and tips receive with great thanks:)

Freddy no electrician:(
high up in the cold north.
still over a meter of snow: (


>>>I suck at electricity too, and am grateful to have smart people
living near me who can help me sort out issues like this when they come
up for me or Lori.

All I can suggest is to first look at the headlight wiring diagram that
Bill Taylor has so generously created and Mike Dailey hosts on his
website, here:

http://www.panteraplace.com/page107.htm

The relevant diagrams are in the "D" section. 

Note that Ford changed the wiring scheme for the headlight doors very
slightly for the last few hundred cars, of which yours is one (good
thing you supplied your serial number) and Bill Taylor's diagram does
not reflect that change (perhaps Bill would be good enough to conjure up
an updated addendum for those later-series 1974 cars?). If you are
following the earlier wiring diagram perfectly, that might explain some
of your problems?

A brief description of the basic connections to the early relay appears
in TSB #7. The description of the change appears in Ford's TSB #14 (I
think you have all of those on CD from the POCA store, right?) but when
I look at the diagrams in TSB #14, I am very, very confused. Ford didn't
do a good job of explaining what the difference is between the early and
late relay, nor do they do a good job about describing how ALL the wires
are connected. They do describe how to bust open an early relay and
convert it to the late style, so if you busted yours open and did the
opposite (add a bridge between two circuits instead of removing it),
that would then allow you to wire your car the way all the previous
Panteras were wired. 

Or so it seems to be. The Bill Taylors and John Buckmans of the world
really need to step in here and run with this problem...I am way out of
my depth!

Mike
