Can someone tell me what a correct 1960 ballast resistor looks like ? I have seen several versions and now are confused ? I know it has the breakaway section on the end. Has anyone got a good photo or can explain what I should be looking for. Stewy

Re: What Do I Look For In A 1960 Ballast Risistor
HHmmm Hello you wont catch the flu if you tell me what I should be looking for. You know it's that little white ceramic thing with wires on it. Please !
Is it meant to have a black dot on it ? and does the bracket have a cut out section or is the metal bracket that holds it solid all the way ?

I worked it out ! All on my own. Don't you love talking to yourself. StewyComment

Re: What Do I Look For In A 1960 Ballast Risistor
Since nobody else has posted pics, here's two of a firewall resistor I pulled off a junkyard '60s Chevrolet product. My Chev parts catalog says all 12 volts 1955-up; 1.8 ohms (blue stripe) for lo-horse engines, and 0.3 ohm (black dot) for hi-horse.
This one was sprayed with black paint on front face, so original color marking was obliterated when I tried to clean it up. But these pics show the break-away tab, the Delco Remy stamping, the spot weld mark, the horseshoe opening in the bracket, and the wavy bracket bends on the backside.

Wayne thanks for tuning in. Those photos are awesome !!! It's funny I have seen about 50 resistors and they all seem to vary slightly. I have seen several like your photo but with rounder edges where the breakaway is. I'm pretty confident what I have purchased is correct. The black dot is interesting, your Chev catalogue says Blue stripe for low horse and black dot for high horse. I have never heard or seen a blue stripe and the judging manual says no such thing as black dot. I have never seen an original with a black dot. Maybe the heat from the current going through the ceramic might fade the black dot quickly ? And what was the black dot made of ? Anyway thanks for the photos and appreciate your time and effort it was very helpful StewyComment

Re: What Do I Look For In A 1960 Ballast Risistor
in NA's book, you will find pictures taken of '60 #2269 - being used as GM's illustration of "stock" during that year and taken when the car was about 8 days old; Underside on pg 223, Dash on pg 250, tach on 251, trunk on pg 255 and the engine compartment on pg 286.
NA was kind enough to make a copy of pg 286 because it was 3 units away from my #2272 - a 16 X 20 enlargement of that photo reveals a black dot on the resistor.Comment

Loren my car is 98 cars older than yours !! #1270 I can see that black dot on page 286. So I gather the JG is incorrect on stating that it is not meant to have the black dot on it. Do you think this car #2269 being a high horse car would be the reason for having the black dot. Mine is a 230 hp and wonder if it is meant to have a blue stripe ! StewyComment

Re: What Do I Look For In A 1960 Ballast Risistor
Another encounter with "new math"; no wonder I was always unable to help my kids in school: 2272 minus 1270 =s 98 (?). Count your blessings, your car should be one without a VIN stamping.
#2269 was a low horse FI car but as I recall those were included with the 270 and 290 HP category of ballast resistors.Comment

I forgot a measly 1000 cars in between OOPs I just got out of bed it takes a good 10 hours before I wake up. To many beers last night. So 2269 is a low horse car. So what do you think my little pup should have. Where did you get your info from Loren. StewyComment

The resistor drawing shows that the black dot identification was added in June, 1961.Comment

Re: What Do I Look For In A 1960 Ballast Risistor
FirstFirst , pg 284 middle picture, a '59; then pg 371 upper RH, a '61; are these not also black dots?
Second, my Oct 62 parts book does NOT reflect the existence of two different ballast resistors, BUT my Nov 63 parts book DOES.
My theory, which I CANNOT prove is that all resistors up to the creation of the blue stripe ohmage resistor were stamped with a black dot as an
INSPECTION MARK, not as an identification mark. I cannot locate the copy of the TSB/or ? that called out the blue stripe and the black dot as defining ohmage of 1.8 & 0.3.
In short, my view is that you should have a black dot. Then again, I am the ONLY member of NCRS that has a negative Judge's rating -1,1Comment

Re: What Do I Look For In A 1960 Ballast Risistor
John, Loren has a point the car in Nolan's book has a picture of a ballast resistor with a black dot ? 1960 ? I have also seen a photo of a C1 with a black dot. I suppose it's one of those things if you weren't there at the time of installation we will never really know. But there is a black dot on a 1960 in Nolan's book so I'm pretty sure my car would of had one. Hence the reason for Nolan's book. StewyComment
