Using another battery is not the best scientific method to test a battery with, unless it was tested on a machine. Getting it verified on a test machine under load for specific gravity is. I agree that it is most likely a wiring issue. Just because you have a 6V battery does not mean your wiring is set up for the 6V/POS GRN system. The 9N starter used 1-wire and did not use a relay (Solenoid). The 9N used a 1-wire/3-brush 11 amp generator with the roundcan cutout. The generator or alternator if 12V, must have a fan belt tensioning device otherwise your system will never charge the battery. The circuit also uses the Ballast Resistor. Here are Pictograms by JMOR and other documents for the correct 9N/2N wiring 6V setup. All 9N & 2N wiring was the same after s/n 9N-12500.
9N/2N WIRING AFTER S/N 9N-12500:
