HiYa Dan. Where are you seeing a resistor in the circuit? There is no such thing on the NAA. A 6V battery does not mean it is wired correctly for the system, positive or negative. Get out your Essential Manuals and use the wiring diagrams to diagnose the wiring setup. Disconnect battery first and use a VOM set to continuity not a test light. Don't go by wire colors, don't assume. Take no shortcuts. BTW, it is much easier to jump start your tractor with your 12V car or truck, no need to pull it around the yard. You have to know the correct way to jump start it though, it matters.
