You've obviously got a direct short to ground somewhere, probably in a harness that goes to the ignition panel.
There should be a T190 book in the manual thread that will help sort finding the circuits, but a visual inspection of the loom should reveal the problem. It'll likely be at a pinch point, or where something rubs against it. The wiring in normally routed away from problem areas, but if a tie wrap or other securing method fails, it can enter harms way.

there is always putting it in the dark and turn it on and look for the flash, remember we did that back in the day looking for bad plug wires. well I did anyway.
