I am rewiring my 48 truck with a 1967 250 Chevy truck engine. I do not have the HEI system but have points. I ordered a new ignition coil from LMC truck. When I use my multimeter with the positive probe on the positive side of the coil and the neg probe on the center where the wire goes over to the distributor I read 10 ohms. With that coil resistance do I need a wire resistor or ballast resistor upstream of the coil? Also with regard to hooking up the solenoid I know that the s on the ignition switch goes to the s terminal on the solenoid. There is a small terminal on the solenoid marked r and I think this should connect to the positive side on the coil to provide spark during cranking, also a second wire goes to the positive side of the coil and then to the run terminal on the ignition switch. I have searched the forum for this and think it may be correct but I wanted to check with the experts. Thanks for the help
