I have a Special Deluxe that is supposed to be positive ground. The battery cables are hooked up positive to the solenoid and the negative to the generator mount. I recently traded another car for this one and the previous owner said it was running great until a month ago. All the interior and exterior lights work. The motor turns over really slow. I have checked and cleaned the points, have good spark, replaced the coil, rotor button and had the battery tested. It was good and then I noticed how the cables were attached. I found in the manual that came with the car that the cables are supposed to be exact opposite of the way I found them unless I'm reading the diagram wrong. Any help would be greatly appreciated. Have a great day.
