A - wiring and battery Question

My brother has my grandad's A from 1946. After he fixed it up and repainted it it seams to eat batteris and I'm wondering of it is wired right. Batteries seam to drain completely and die with in 6 months. It has a coil and distributor 6 volt system. The wire from the battery runs into the light switch box and then to the kill switch and then to the coil. Shouldn't the switch be between the ligths and the battery. After reading a couple related posts I'm also thinking I need to check the coil if it is wireed right positive or negative. My brother said the tractor was positive ground.

How should the kill switch be wired?
How should the coil be wired?
How do you tell what the ground is positive or negative?
Could the light switch be draining the battery with a stray voltage draw?
 

This will help.
The Kill switch is actually an ignition switch. it supplies voltage to the coil. It should only control the coil supply, no other components should be in that circuit. The cutout relay in the voltage regulator (if it is equipped) or the cutout relay (stand alone) with 4 position light and charge control switch, Eliminate battery drain when stopped.
Which do you have 3 position Light sw, or 4 position, (or if you know, if it is VR, or cutout)? Jim

I'll look tonight and find out. I dont recall how many positions are on the light switch. I do know this tractor was switched from magnito to generator back in the day.
