A 6V battery alone does not constitute a 6V/POS GND system. The ENTIRE WIRING circuit must be correct and quality parts used. As Bruce said, go to NAPA -most are Made In the USA, and by the way, there's no such thing as Ford Tractor anymore. You may have gone to a CNH dealer who sells aftermarket Ford parts, but stop. Too expensive for one. Verify wiring is all correct. Be sure battery is good, will sustain a charge under load. Disconnect lights from the circuit. Eliminate one possible cause -can reconnect later. Test wiring via continuity, not an idiot test light, using the pictogram as your guide. Forget wire colors -no two wiring harness manufacturers are alike and very few adhere to the original colors anyway. Idiot/Test Lights require power. You DO NOT want any power thru the circuit when you check continuity. Keep battery ground disconnected. You can use a digital multimeter only if engine isn't running. When running, static electricity will cause kattiwhompus readings. Use an analog meter when engine is running. You last statement is a typical reaction, a myth, created from those who don't really know how to troubleshoot the electrical system. If the tractor isn't running now on 6 volts, what makes you think it will on 12 volts? Here's fact: 99.98% of all non-starting/non-running issues are due to incorrect/bad wiring jobs, regardless if 6V/POS GND or 12V/NEG GND. A root cause problem solving method is needed to solve any problem. Go slow, step by step starting with good ECHLIN or BLUE STREAK POINTS, timed correctly, and verifying the wiring circuit is correct, including the wiring to the VR and genny. Then you can connect the battery and proceed.
