On 6v make sure the battery cables are large -- 0 or 00 gauge -- and the battery is in good condition and of sufficient CCA. Also that the grounds and all connections to the module and coil are good and clean.

If the starter needs work or engine has issues starter could draw excessive amps when cranking. If all the above is not in pristine condition the current pulled by the starter and resulting voltage delivered to the solid state logic in the electronic ignition module could easily be too low. The logic type used will not tolerate much of a voltage drop. It has a narrow working range and anything lower than about 5v at the module and it most likely will not fire or will be very erratic.

Many many 6v Pertronix units have acted up enough that they had to be pulled. Not necessarily because of the unit but because poor wiring or other conditions caused the units to misfire. 12v cars do not have the issue because there is a lot of room for voltage drop as compared to 6v cars.
