John Deere 4020 Electrical

I have a 1965 JD 4020, and my gen light is always on. I cleanes out the generator, replaced the regulator, but the light stays on and I am scared to use the lights, and I have to recharge my batteries every few days. I try to polarize the system, but there is a very faint spark there where there used to be a big blue flame. Any help on this one? Is it the generator? or more serious?

Thanks
