The black wire from my alternator came off the + side coil when I looked at my saved pics before replacing .
I added a key on wire to the + side for the ecu only . Fires fine now
When running, and I turn the key off, it does stop running .
You made perfect sense in your helpful statement...
Thanks, this helps a lot , I have it wired right because the blue from the box wants key on and the big wire from the alternator share the same side ballast resistor no matter where the splice or connection is.
Right ?
