No start when cranking
Is this 2 or 4 terminal ballast resistor? If this is a 2 pin resistor, might be the start circuit, either ign switch, connector, or bulkhead connector
There is a separate contact in the ign switch which feeds power during start out through the bulkhead to the + side of the coil on the brown wire. This is known as "IGN2" or the "bypass" circuit
