Measured the current draw for two Sparton Model L-A Trumpet Horns of a '32.

Continuous current draw was 7A from the battery, measured using a digital meter. Battery charged to 6.6V, with 800 cold cranking amps capacity.

Correction to my previous post of 4 ohms resistance - The resistance would be 0.94 ohms for the pair.
