KRW Timing Fixture

[91A-77B]

I recently bought a KRW No. 41-F-2993 dis't timing fixture, and need help to understand the batteries used in powering it, and the wiring connections. I have the operating instruction sheet, but no mention of batteries. I assumed, because of its age, that "D" types would be used, but they're not the right size (2 are too short, and it won't accept 3). The other question is the 2 wires that extend into the base box with the batteries. They appear to be hooked up to 2 studs with nuts, but would this not short out the batteries? There is no insulation between the end clips. I'm sure, if you have one of these units, you will be able to help me out, and I'll send you a photo copy of the instruction sheet if you need one. Thanks!

It may help the Ford Barn members viewing your posting if you added a photo, photos of the timing fixture.

Someone in the past may have made changes to it over the years.

I'm not near mine right now but I always use two D batteries in mine.

I took a wall ac adapter with a couple of alligator clips...no more batteries needed.
Mine was 4.5v from start...may be a swedish version.
Now 24v lightbulb and wall adapter.

Here is a picture of mine. Are you sure that the battery contact clips on each end aren't missing?

There is an option that I find much easier than depending on the original light bulb/battery setup.

I like using my multimeter with its continuity beeper.

Listening for the sound while focusing on the degrees works well for me ... plus, the batteries and connections, etc., do not seem to have the sensitivity of the meter.

Nice to have one's KRW in original configuration, but using a meter does not undo anything.

(It's now time for the usual lecture about "the only way to correctly set up a distributor is ... ")

Probably best to include a picture. The responses so far are more pertinent to the KRW V-126 timing fixture. I haven't been able to locate a reference to the number you gave.

[Hoop]

The number, 41-F-2993, suggests a US military identification as a repair fixture. Most likely added by the Army or AF ... interesting history.

Edit: The original poster has not responded, but he may actually also have tech manual instructions that came from the military and that have that number ... rather than KRW instructions. May never know. Curious.

(Bruce Lancaster is supposed to handle this kind of research stuff.)

Heres my unit, purchased it about 30 yrs ago, usually when I buy something I write the price paid on it, $25.00, must admit I didn't know what I was buying, just recognized the KRW make and at the time I ran across this I hadn't bought anything at that flea market, was Dunkirk I think. Am guessing it might be worth more than what I paid, I try to keep my shop contents up to date with item list & value of what's in there, what would be a good $ value on this. Also is this a complete unit ?, anything missing ?

That´s a nice complete setup with the 2-bolt adapter and the adjustable dwell scale.
Think i have 2 of the cam slot adapters in mine.
Have to check what the marking on them says..
What you have there is the best version so should make you some good money...se them go for high $ on Fleapay.

Thanks for the feedback, guys. My unit appears identical to Bob/Ohio and oldasi's. I'll have to go back and figure out why 2 D's are too short. Anyhow, the pics helped me understand the wiring in the box. Although fairly dirty from long storage, mine seems to hardly have been used. I'll post pics of unit and instruction sheet (which is original, almost mint, and printed by KRW). By the way, have your units got s/n stamped inside bottom of box, like mine?

[bruce lee]

I have an original instruction booklet down loaded from a friends. I just took pictures of his. Every interesting. I could share if anyone needs it.

[Bob/Ohio]

Mine is stamped in the bottom left front corner of the box, 41-F-2993 U.S.A., and my instruction sheet also has 41-F-2993 printed on it. As far as 2 D batteries being too short, they will seem to be as the contacts for them are not at the end of the battery tray, they are next to the wires as you can see in my picture.

Post that instruction booklet! I bet a hundred people on here would love to see that!
D's for sure. One of mine (which looked like it had never been used) actually came to me with a pair of 1942 dated D batteries in it. They were perfect in appearance, and had never leaked or produced any visible corrosion on themselves or the fixture.
On old stuff like flashlights I like to just put a plastic 2-AA holder wired to a modern whaddycallit bulb...batteries and bulbs then last and last with no fuss.

Bruce(Lancaster), search online for 41-f-2992 ... almost suggests a GI identification.

[Bob/Ohio]

Bruce,
Here are pictures of my instruction sheets that you suggested I post.
