Re: 1937 ignition coil specs

The chances that no spark at the plugs is caused by a bad coil are relatively low. Just to eliminate the cap and rotor, verify that you have spark from the coil. Your most likely culprits, assuming good connections, are a shorted primary feed to the coil from the ignition switch, a failed condenser, or bad/misadjusted points.

A key question, is your ammeter indicating a current draw by the coil as the engine cranks?
