The Crane module seems to run hotter on the point
conversion systems with transistor ignition.
I believe the reason for this is that the coils on the transistor switchgear units is made to run at the lower voltage. That is why some who race these opt for the later coil.
However, for street driving, the early standard Bosh coil [230/250SL type] are fine and more compatable to the Crane units. They run much cooler and can be used with a standard resistor set-up.
Crane recommends elimination of switchgear, standard coil and resistor . No need for starter by-pass for starting.
