The device at the referenced link is what I have on our ?55 C-300. The female end is sized for the OD and taper of the negative post, but I thought it best to install it on the larger diameter ground cable (positive terminal), even though it did not fit the post particularly well. The copper/brass material is not as soft and compliant as a lead battery cable clamp end. And, it popped off in normal service. I have since relocated the device to the negative (hot) post. This results in minimal clearance (1/4?) between the lead cable clamp and the steel OEM battery holddown. Everything is tight and stable, but it is not the best and safest alignment. I added a small piece of fiberglass material between the cable end and the holddown ring to act as insulation in case of impact/shock/vibration. The device does work well, but I think a designer like Gary could have done a better design that would have kept the cable clamp and the accessory clamp in the same plane rather than forcing a right angle between the two. The lengths of the existing cables limits the options, especially the hot negative cable that connects the negative battery terminal to the starter relay. Newer batteries that are held in place by clamp plates at the bottom would not have this problem/concern. I have a similar quick disconnect device on the side-terminal battery of our RV and that installation is safe, stable and also works well. I strongly recommend a quick power disconnect device on all vehicles where one can be installed safely.

I highly recommend them for those exciting moments when you MUST disconnect the battery. Except for hitting the brakes and having the pedal go to the floor, there is nothing more frightening than to smell or see smoke escaping from some electrical wiring or component on our pride and joy 300's. You never have a wrench to remove the cable at that exact moment. The problem that you seem to be having is probably because the "Proper" way to disconnect a car battery is to first disconnect the Negative cable and then the Positive. In reconnecting the cables, connect the Positive terminal first then the last connection is the Negative cable. I know this sounds backwards and I cannot scientifically explain why, but do a Google and look it up. The quick disconnect terminal is made for the Negative cable. I am not sure but as I recall, the last time I bought one, they also make one for both terminals.

I had installed one of those quick-disconnect cable ends on the (positive) ground cable of our 1955 C-300 and it mounted neatly and worked fine. On the way home from the 20th Annual MoPar Rally show today in nearby Fremont, CA, the clamp-type connector just popped off the battery terminal at a highway stoplight. Embarassing and aggravating, but easily diagnosed and fixed. The clamp connector is made from a rather stiff brass-like material and apparently sized for the smaller diameter negative battery post and may have an improper taper. I remember having to tap it down to fit the larger positive post and that it seemed tight. I have no solution for the misfit but I may try to grind some ridges into the ID of the clamp so that it will hold better. The clamp may have come off due to some vibration I experienced north of 85 as I had the bias-belted L78-15 Remington tube-type tires static balanced to avoid ugly wheel weights on the outside rims of the Motor Wheel wires. A misteak. There was a 10-15 minute delay at the check-in line for the show this AM and our C-300's temp gage and the driver really got up there. After parking, the C-300 turned into a Stanley Steamer and was boiling away nicely and puked out a quart or so of coolant. All this might have left me hot under the collar had our car not won first in the 300 Class (there were five other 300's entered-including members Lee Newman's Tango Red '55 and DeAndrea Vantree's Black C coupe-also E, K & L coupes-a very nice mini-meet!) This was also the first meet where I saw the Viper Red '56 Windsor convertible that has been extremely well modified with a '56B interior and exterior trim and grill. Members Richard Palmer and Henry Hopkins displayed their new creation of what might have been driven by a 354 engine, replete with Delta Wing air cleaner and AOD TorqueFlite. They displayed the car with full disclosure that this was not a letter car but was a one of none car-something that coulda/shoulda been. The car's personalized license plate reads "FANTUM B". The car won first place in the "Convertible" class.

Bad connections at the battery will as well as a bad connection or cable anywhere in the power supply system. Most seen battery cable problem is with the clamp fixit things that get installed at the battery posts to replace bad cable ends. They are nothing but trouble and need constant maintenance. Complete, new, high quality cables ahould always be used when ends or cables are bad. Temp ends are high resistance connection at best so there is a voltage drop even though enough poop may get through to start car. An open ballast resistor will result in a crank, start, but not run situation. Voltage readings you posted look good. If ballast resistor circuit goes to ground, engine could crank but not start. Or, the short to ground could result in major wiring and ignition switch damage.
