Update on 73

[4x4man09]

Ok, awhile back I posted about my 73 not shutting off when you turn the key off. We tried everything that was said with no luck. Truck runs fine even when you shut the key off. The only way to shut the truck off is to pull the main coil wire, then it will shut off. We put the coil wire back on and gave up for the day. When we came out the next day the battery was dead. So now we have to pull off the battery cables so it doesn't drain the battery. From what we have seen no wires are pinched or cut. If worse comes to worse, would it be possible to put a toggle switch in that will shut it off if the key is off and to make sure it wont drain the battery?
