Voltage drop at ballast resistor

The voltage at solenoid relay reads the same as the battery. The bulkhead connector male side reads the same as the battery and solenoid.
Are you back probing the bulkhead or did you remove the connector?
Sorry if that's obvious, bt just want to make sure there is current flowing. Otherwise even a poor connection will read same as battery (see my explanation for voltage and curren earlier in the thread)
