I don't beleve 3 volt is enaf for the coil it has to be at least 9 volts
if this car has a resistor on the car or on the circuit going from ignition switch to ignition coil replace it, but if it does not have one then it has to have one built in the circuit wish is going to be very hard to find i will recomed you to get straight ignition power from ignition sw, to an aftermarket ignition resistor and from there to the positive side of ignition coil,
but also let me know what promaster means? is that the brand? or is that a performance coil?
and does your car has elecgtronic? or points system ignition distribuitor.
