I'm fixing up a 1966 IH Cub Lo Boy. Bought a new set of points, plugs, condenser, plug wires, distributor head and coil. (12V)
However--no spark! I have 12V to the distributor plus terminal. Also, checked continuity in the plug wires wherever I could--it's OK. I decided to check the resistance of the coil primary and found it's open (infinity). It is a brand new 12V internally resisted coil.
First question: shouldn't the coil have some resistance, maybe a few ohms?
Second question: If it's bad and I think it is, would it better to get the hotter coil that requires external resistance?
Great forum! Thanks for your help.
