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.

Default Puzzle

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.

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

Would it have had the early rubber light? That would satisfy the smaller size of 11/16".
If that bracket was taken off and fitted on the other side, on the 2nd bolt up, then the light would maybe shine down on the white paint.

Is there any evidence that reinforces the idea that the convoy light was mounted to the diff other than that is where it was on Peter's Lynx ? I still think that it is a crazy idea as the vibration would have made the bulb life very short.

David.

I was wondering about that also. Any other convoy light bracket I have seen was frame mounted and punched/formed from heavy guage sheet steel. This one on the Lynx looks to be made from far heavier bar stock.

If this mount and location are correct, could it be that the Engineers at Ford anticipated the vibration problem and went with heavier bracket material to dampen out the vibration. The earlier, rubber convoy lamp may also have been chosen as an aid to reduce vibration as well.

Another consideration would be what the actual wiring harness has to tell us. Does it include a line for a convoy lamp? Where does the harness run on the vehicle for the back half of the vehicle feeding the tail lamps? What locations would any existing convoy lamp wire reach, or not reach, to connect with the convoy lamp.

An interesting mystery!

David

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 mounting location looks wrong and incorrect as it does not serve a purpose by not illuminating the white painted area and it being low mounted looks like it would be snagging and torn off in due course. Like others I feel someone, somewhere installed it in the wrong spot. Anyways as the owner/operator (and restorer) of the car you have complete licence and agency to mount it anyway you wish. One of my beliefs is "if it looks right.......it is right".

I just crawled under the lynx here at the RCA museum. There is nothing indicating there was ever a convoy lamp, nor is the diff painted white. Perhaps someone back in the day found it advantageous to install a convoy lamp on your vehicle due to whatever role it was involved in. The lamp you show does not appear to be the normal Cdn lamp....it almost looks more like the post war convoy lamp from the 50s, but not quite.

I bet there was a factory convoy lamp of the standard variety. Most likely it was mounted with an L shaped bracket to the inner, underside of the hull. What may be disguising the hole is that is was used for a dual purpose and is currently filled with a nut and bolt. The other thing you need to figure out is where the 'red/white' toggle switch was mounted. This is the one that sends the current to either the two red tail lights or the white diff light.

I spent a bit of time last night going right through both of the spare parts manuals I have for the Lynx and could not find anything to even suggest that there ever was a convoy light set up. Nothing in the wiring loom, diff details or any where else. Looking at the Lynx from the rear, you cannot see the diff unless you get right down low and look up. Maybe your late model Lynx had it but my earlier Mk.111* certainly doesn't.

Perhaps an 'aftermarket' white disc as on carriers? The reason I say there should be one is that it was a standard identification that all vehicles had and all troops were familiar with. To say Lynx didn't need them seems odd as the soldier or driver behind any vehicle would expect the lamp and wouldn't necessarily know or care what kind of vehicle it was. That is unless there is physically no way of mounting something under the vehicle that would be visible.

As I posted earlier the wiring diagram doesn’t appear to have a convoy light.

Default Back on the shelf

Guys,

I truly appreciate each and every comment. The bracket is now back on the shelf where it will remain a wonder. The lack of documentation and the lack of an ID on the wiring diagram plus the fact that that the bracket does not accept a normal convoy light were major factors. The clincher was when Rob confirmed that the RCA Lynx doesn't have a convoy light since I know that the CWM Lynx doesn't either.

I continue to be amazed at the knowledge within the MLU community and the willingness to share.

Thanks again, Peter

After looking in both the parts and maintenance manuals, I agree with Jordan. I didn't find reference to an axle or sub lamp, a switch for it or a bracket to mount it on. The lamp and wiring are filed with electrical in the F15A parts list but I also looked in the frame, hull, instrumentation and rear axle sections in case they were filed differently on the Lynx. That said, it is always possible I missed the relevant items.
Is there by any chance a part number stamped on the bracket? If so, I can try again.

Default Manual workout

Grant,

I can think of at least four Lynx/Ford manuals that have had quite the workout (yours, Jordan's, Rick's and mine). There is no part number on the bracket and it is of an unusually heavy gauge - 3/16". I am now of the mind that this was a post war add on.

Harry,

The remnants are very similar, again not a logical fit for this location.

Thanks, Peter

Default Trouble light socket

The maintenance manual points out both a dash lamp in figure 1 and a trouble lamp socket. Does anybody know of the location of the trouble lamp socket?

Default Diff paint and trouble light

Bruce,

There was strong evidence that the LH side of the diff was painted white, couldn't determine if the RH half was painted (badly weathered). Since the diff is biased to the right, the LH side of the diff is close to the center line of the Lynx. The question that I can't answer is when it was applied.


Harry,

The trouble light socket on the Lynx 11 is on the lower LHS of the instrument panel. Mine is currently empty and I seriously doubt that I will ever install a plug in for the windshield defroster plug. (top socket hole of the LH side of the instrument panel). The "Light-Instrument Panel" is just above the speedometer.

Peter

Default Another puzzle

Guys,

There are two heavy duty (1/2") eye bolts on the sides of the hull and while I can find them on illustrations in the maintenance and parts manuals, there is no part number for them. My question is - what purpose do they serve ? My old LH slanted bin also has a lighter eye bolt on the front side and I have photographic evidence of two additional eye bolts of the front storage bin. Again, does anyone out there know what purpose these eye bolts serve ?

Thanks, Peter

This is a guess, not founded on any evidence - to provide securing points for lashing a tarp?

My first thought was lashing points but why not just weld a loop on instead. The fact that they are adjustable might suggest that fixed length metal hooks latch into them and they must be positioned just right to serve their purpose.
