Excellent! Fuel issue resolved. Now moving on to the electrical. The generator cutout voltage is 7.0-8.5 Volts but it is the AMPS your looking for. Your setup may vary depending on what you have. You say you have a '39 9N. If it is and original, it would have the small 2-Wire/2-Brush 'B'-Circuit generator, a square VOLTAGE REGULATOR; and use the 6V POS/GRN system. Look behind your dash on the steering column, Do you see the VR or is there a round-can cutout? Is the generator a 1-Wire unit? The two early '39 gennys had a 7 AMP output. After s/n 12500 the 1-Wire/3-Brush genny used the round can cutout. The later 9N-10000-C genny now had output of 11.5 AMPS. You will need to verify s/n to start with, then verify which setup you have. Here is the wiring for the post s/n 12500 using 1-Wire/3-Brush genny and the round can cutout:
