A 12 volt draw on battery from a one wire alternator

Thanks for the advice and sorry been working so just now getting a little time to tinker. I'm not sure on alternator which field wire goes where. I have the green and blue field wires. I have swapped them and shows nothing different. Alt. is reading same as battery. I checked all other wiring. Is a single ballast resistor ok with electronic ignition? The bulkhead wiring there was some not so tight connections. I don't think that's my problem though. I don't think alt. is charging even though advanced says it was putting out 15 volts. I will post some picks in a few.
