Ok if the choke is to ignition on only you should be fine. Like I said if you remove the neg cable and put a test light between the cable and battery with everything off including domel light, hood light etc. The test light should remain off. If it's on then something is pulling a load off the battery while it's setting. If nothing is I would check the battery cables good especially if they have had the ends replaced. The corrosion can leach it's way under the rubber coatings and cause them to have a lot of resistance. That's why it seems to start fine with a jump because you are adding extra amps to overcome what your loosing in resistance. I have took cables off that physically looked fine but the copper under the coating was corroded and green packed with crud and not allowing for a good flow of current. Think of your cable like a drain pipe no matter how large if junk starts building up flow slows down . It starts small and keeps collecting getting worse till it backs up to a trickle. When you Chang ends you start with a bad connection to begin with and then depending on what replacement you use (usually cheap bolt ons) the different metals react to make corrosion. Electricity and water enhance that reaction. It could also just be a battery on its last leg. But from my experience if there was not a draw/short. It was 9 out of 10 the cables or ends. Usually if it's starter cyl you can tap it and it will try. But a low battery or weak amperage will cause the same symptoms.
