BR Coil vs. non-BR

[Floyd B.]

Is there any difference between Delco Remy ignition coils embossed with BR or B-R and coils that are not?

Re: BR Coil vs. non-BR

All I know is that BR stands for ballast resistor. TI coils, for example, have no BR.

Re: BR Coil vs. non-BR

So does the BR indicate the coil has an internal ballast resistor, thus it does not need an external ballast resistor or resistor wire? My '69 390HP car currently has a 287 B-R coil with a new engine harness from M&H with the resistor wire to the coil. It seems to crank and run fine, but does my coil connection now effectively have two resistors in the path to the coil?

Thanx

My understanding is that the coils marked (or de-bossed) BR or B-R are for use with an external Ballast Resistor or resistance wire. There is no internal ballast resistor.

That belief comes from conversations with a friend (RIP) who wound coils for Fords (can I use that term here of will the nannies make it ****?) vehicles. And yes I tried to get his equipment when he passed, but his fellow **** enthusiasts got there first.

Terry,

That would make sense, since my ignition seems to work fine. It's interesting that the TIM&JG states that original 287 coils did not have the B-R but all points ignition cars used the resistor wire.

If my memory serves me right I thought all 287 coils had the B - R embossment. I have one that has it but It seems that all I have seen do as well.

Thanx Dave,

The one I have has "B-R" but it is far from being original to the car.

Re: BR Coil vs. non-BR

I still have the original coil that came in my 69 and it has the B-R on it.

Re: BR Coil vs. non-BR

Jeff,

Which engine option do you have? According to the TIM&JG, "Those numbered 270 and 263 may have 12V or BR below the numbers about one-half inch down from the top. Those marked 272 and 287 have only those numbers about 1-1/2 inch from the top."

Re: BR Coil vs. non-BR

It is a small block automatic. car built in October of '68.

Re: BR Coil vs. non-BR

TI or points?

[Jeffrey S.]

Re: BR Coil vs. non-BR

The car has points ignition.

Re: BR Coil vs. non-BR

That would match the information in the TIM&JG, ""Those numbered 270 and 263 may have 12V or BR below the numbers about one-half inch down from the top." 350HP with standard ignition had 270 coils.
