You should be able to measure the primary resistance as slightly over 3 ohms
if it has the internal ballast resistor.  If not, add one between the coil
15 and the ignition feed, and (if you like) put a hot link direct to the
coil 15 terminal from the starter solenoid wire.  That gives extra spark
just at start-up.  The Bosch red coil was designed to have an external
ballast which could be bypassed for starting - quite a few Type 3s here had
them fitted to help in damp weather.  I could have done with one on
occasions.
