Re: Delco Remy

Rich,

Yes, you are correct about the ceramic.

By the way, you can help yourself a little by black dot.

Re: Delco Remy

The pics are all service replacement parts. Not correct for originality or NCRS judges. My 63 FI car has a NOS 091 coil on it and a NOS real deal D1111.
The round end with the bolt hole. Should be sheared off!!!!! Big bucks for the correct part.
The black dot thing. Judges thing gang. It's totally incorrect. There is no black top on the D1111 that came down the St. Louis assembly line.
In pics it may LOOK like a black top but in fact it's spot weld!!!!!
The old judges here know that but are not chirping in.
Learned about D1111's long time aqg from Jorjorian.
Now heres a good trick. IF you have an old original and the porcelain is broken or cracked. Buy one of the service replacements like in the photos. Use it for parts. Barry Holmes of the Pittsburgh chapter taught me this long time ago. Slice the back side of your zinc cad piece. Get it cad plated. Take your new one and use and use it for parts. Tack weld the back side together and you have a cheap real deal part.
Story: In the late 70's I used to get all the free Chevy parts I wanted. I order two dozen of those D1111's. Had them for alll these years. Found out they weren't worth squat for judging.
Just like the 30 sets of exhaust tips I squirreled away. When my 63 was re-restored the exhaust tips were crap.worthless.
Had to get the63 dented ones restored.
Later as going out to eat. John D

Re: Delco Remy

So are you saying remove the black "Magic Marker" dot? Makes sense that no "dots" were on assembly line cars. No need.

But for service replacements, I always thought the black dot was to specify 0.3 ohms and the blue dot was 1.8 ohms for the later part after 1963. This due to both parts visually identical but different values. Probably to help the guys at the counter differentiate them.

Yes, Rich, no dot would have been used through '62's.

This surprises me. I would have thought that the "dot" system would have been more of a PRODUCTION-utilized kind of thing. In PRODUCTION the resistors were supplied in BINS. So, the line workers would have needed some way to differentiate the parts. This might not have been so important for the Corvette line but could have been much more important for other car lines. In SERVICE, the resistors were supplied in boxes with the part number on them so the dot would really be unimportant (although if such a feature were used for PRODUCTION purposes, it would likely be carried over to SERVICE pieces).

Joe, Good point, but the consensus above is no dot and I didn't know that.

It seems that the ONLY ballast supplied on the line up to 1962 was the correct item, so maybe the identifier dot wasn't needed? After 1962 when the change of value to 1.8 ohms came, maybe that's when the dots showed up. ???

For Corvettes it would not have mattered until 1963. However, I believe the 1.8 ohm resistors were used on some other GM car lines well prior to that time. For any assembly line which used both resistors there would have needed to be some way to quickly ID them. Of course, they would not have made special "non-dot" resistors just for the Corvette assembly line. However, I am not saying that PRODUCTION Corvette resistors had the dot; I'm just saying it surprises me that they did not.

Re: Delco Remy

Joe, I would agree, To this day, the only way to know is with a ohm meter. I don't trust dots regardless of the markings.
