Hi Peter.

Check your first photo in Post 66. That might be what you are looking for.

David,

Many thanks ! If I was younger I might even be embarrassed. I’ll still take another picture should anyone have to share. David, I think it’s time for me to reread all these posts.

Peter.

Glad to help.

I think that is the first convoy lamp setup I have ever seen that was not hard mounted to a rear frame crossmember somewhere behind the rear axle assembly.

Mounting it directly to the back of the axle would mean the lamp was always on target regardless of any axle movement. Be interesting how much slack was put into the convoy lamp wire to allow for the axle movement and where the wiring was run.

With a frame mounted convoy lamp, extra wiring would not be an issue as the lamp could not move, but now I am wondering just how much of a problem it was with a fixed mount frame convoy lamp and the target axle moving about on rough terrain, to make Ford consider this design option for the Lynx?

Keep up the great work, by the way, Peter.

I know I did (re-read all these posts). I'm impressed all over again at the work you did on that bisected relic you started with.

I think that the movement of the diff would be insignificant compared to the rather unfocused pool of light from the lamp. On the other hand, mounting the lamp on the axle will have greatly increased the vibration it was subjected to so bulb life would have been very short. I think it was a dreadful idea !

I totally agree with Bruce's last post !

Peter,

Maybe you did find the bracket bolted to the axle, as someone sometime may have re-fitted it there.

But it does not make any sense to mount the axle flood light there. The bracket has the typical twist and downward axle to shine a light on the differential from a position on the chassis. I would spend my time on finding the correct location on the chassis.

HTH,
Hanno

That image shows that the lamp is mounted in a position/orientation that does not shine on the white painted portion of the diff. But no doubt that it does mount to the diff clamshell bolts, but in a different orientation.

Guys,

Thanks for your positive words. I brought the Lynx home with the intent of restoring a tribute to those that have served our country and to provide a challenge for myself in my later years. It has certainly done the latter.

I mocked up the original bracket as it was found and discovered that when I went to mock up the light that the diameter of the remnants of the original light measured 11/16" and my replacement NOS convoy lights are 15/16". It also raised the question, did the light shine on the differential or was it orientated by 90 degrees to shine to the rear? The lack of documentation on the subject in my Lynx manuals compounds the issue.

I would welcome any suggestions or better yet some pictures.

Thanks, Peter

I'd be very surprised if the lamp shone to the back instead of on the white painted dif. Every other vehicle shines on the dif so why confuse the troops?

The thread size difference takes some explaining however.

Peter.

Prior to your taking possession of the Lynx, it may very well be the last person to service that rear differential put the convoy lamp bracket back on the differential incorrectly.

Looking at your new photo of the mockup, the lamp points straight up and is on the opposite side from where the white paint target is located.

What if you rotate the bracket 180 degrees counterclockwise, so the lamp is now pointing straight down and move it to the left side (bolt head side) and up two bolts. It looks as if in that higher position on the left side of the differential, the beam of light from the lamp would then be on, or very close to the target area.

I was looking over the wiring diagram that is posted elsewhere on the forum and I can’t seem to find a convoy light.

Is there a chance that bracket could be mounted somewhere else under the body. Perhaps try playing around with the light pointing towards the white on an downward slop. The other end might line up to something.

[Bruce Parker (RIP)]

I find it hard to believe Lynx didn't use he same convoy light as all other CMP vehicles.
