Assuming the control boxes are the side mount variety?
If so, there is supposed to be a piece of heavy stiff plastic between the control box case and the key switch. This was added due to the extremely tight tolerances in that area. Check to make sure that is in place. If not there is a good chance the black/yellow may be grounding through the control box case half.
Second, if someone has changed out a key switch the routing of the key switch harness can be quite a task to get right. Check for areas on the black/yellow wire sheathing that may be rubbed through.
If this has a very early key switch (without the raised black/yellow terminal) there is a chance of carbon tracking to ground. Check it.
As far as not shutting off……When the key switch is turned to the off position the black/yellow is connected to the black wire (ground) so check the terminals on the back of the key switch to make sure this is happening. If not, it is your key switch. If it is then ohm out the harness and see if there are opens in either of those two wires.
Also, check to make sure the wires are on the correct terminals on the back of the switch. Your manual will lay that out for you.
This will either confirm or eliminate the control box/harness.
