ask @ToyotaMatt, he might know
I think it means its chicken 
. Maybe a passes inspection mark, or it could signify a change in spec's from ones with out a dot.

I removed it. I have a 1978 FJ40. After discussing the installation of my new distributor that I purchased from you, i was told that there is a resistor wire (pink) from the ignition to the coil. If i have the ballast also in line I supposedly will have too low of voltage going to the coil. My battery is a little over 12V and voltage without the ballast is 10V at the coil.

Hi Sam
so .........
my complete all oem japan spec. Ignition kit you received from me comprising only and all Genuine NipponDenso , SUMITOMO & YAZAKI parts ....
- every single part in my kit is specifically designed and engineered by me to work and mesh with all other parts correctly by the FSM , and also above and beyond the 2F FSM last revised Publication # in both Mechanical & Electrical harmony ...
hence my SNOW VERSION branding of the kit , because it was absolutely with much fore-thought created to out preform , outlast and have a duty life cycle way more and way beyond any Vacuum Advance points based complete overall ignition system that TOYOTA ever produced or had in Land Cruiser Gasoline Engine 1990 & older , F1.5 2F , & 3F carb ....
Please elaborate in detail below :
who , where , and why ?

please DO NOT start your engine or drive your truck at all for now please
thanks

What should the Voltage read at the coil with your ballast in line with the pink wire resistor?

OK ....
I see this above and understand it clearly as well too .....
i do vaguely recall @Coolerman posting a 40 series tech. thread long ago , that showed a burgundy reddish ' long skinny " thing " almost dtiio to a OEM TOYOTA 7.5A glass tube fuse , the color keyed filament inside a 7.5A TOYOTA OEM one is anodized RED .....which is more like a metalic burgendy ,
it was outside the engine bay in a Splayed Open in-place engine bay harness to the inner fire wall side next to the blower motor housing exactly how he outlines above he was working on-site at his shop ...
this was over a decade + ago , so pardon my recalling only these particular details ,,,
i do not recall the resister topic as being the major discussion point in this Tech thread long ago , only as a krystal klear non-adhesive lined YAZAKI heat shrink same in kind as a late modle FJ40 HAZARD switch uses in the exact location @Coolerman outlines above very well .
.
so ......
there is now a topic that is on-topic here , i should mention ..
i have been and am the vintage toyota Land Cruiser Master level electrical system oracle and wire harness maker @Coolerman 's Padawn apprentice for around a decade or so ......
his professional level technical information he has provided you above regarding my yellow dot DENSO Japan. Spec. ignition coil w/ bracket is the final word you should adhere to ....
i plan to find out the exact production date time line in FJ40 and also FJ55 that this unique resister " feature " was incorporated into the engine bay sub-harness ?
there are now 2 modern NipponDenso fundamental leaps in directly related JIS electrical system technology now common place on all 40 & 55 that can incorporate the external ballast resister equipped coil w/ bracket ,
- the life-time points distributor assy. in my kit .....
- the genuine NipponDenso japan. spec. cracker-jack fast RPM gear reduction starter motor ...
- before it's introduction in 5/79 40 & 55 .....
- all land cruisers 40 1961 - 4/79 & 55 1967 - 4/79 came new from PLANT A-11 with a giant Loaf of Bread size-spec single reduction sloth-speed rotation RPM starter motor ..
- it had a 18ga black wire w/ red tracer stripe that upon turning the IGN, key to the START position , in addition to it cranking the Siamese F , F1.5 & 2F , it also sent a 12V B+ signal via wire that by-passed the external ballast resister in the cranking mode only , this would super charge the dormant coil for that single seconds period only , this would help greatly making the engine turn over and start in much quicker amount of time ...
- the updated more modern post Apollo Moon mission gear reduction's significantly faster RPM factor , made this old-skool way method of super-charge coil to get Engine going , especially on cold morning warm up choke cable pulled out fully in the start mode the completely obsolete ,
- hence why a OEM Toyota Genuine Parts genuine NippoDenso brand new gear reduction starter is now in-place in 99.9% of all above F series Engines on all 40 & 55 series Land Cruiser's , as well as all FJ60 ones too .......
- i suppose the fact that the last new TOYOTA Genuine Parts NipponDenso factory remanufactured Loaf of Bread single-sloth reduction starter was sold in November 1983 may be at play here in every way ..........maybe
thanks for the follow up here Sam

So should I reinstall the ballast? Without it I am getting 10 V at the coil. I will not attempt to start/run the vehicle until i hear from you.OK ....

Thanks,

- do you have a gear reduction stater ?
- i was not aware @Coolerman was the source of this little known fact based in-line resister information, ...
- i have been his Land Cruiser Electrical Padawan Apprentice for almost nearly 13 years , i study under him and his teachings , i have also taken all i learned from 4 years of T-TEN formal education , combined it with what he shares with me from his lifetime of what he does , it is a unique privilege to able to connect the 2 schools of though , older vintage , and the circa era. 1994-1988 technology of that time period ...
i also have never heard of removing a ballast resister like you have hear ?
i do not know what will or will not happen here , after the in-harness resister is now a factor ?
- i DO know that if a coil does not an resister on it or inside it like 1988ish and later toyota "
the coil will burn up....
this is why i said to pause here .....@
i suggest you contact @Coolerman again and go over everyone's input whom posted in your thread
please make sure he knows what i discussed hear in detail too of course ....
make sense ?
