Ignition on - not start. Starter relay not energized. Relay
contacts open, no hot. Purple wire TEMPORARILY grounded
by jumper - to solenoid coil - through coil to ground. Equal
potential on both sides of motor/solenoid coil, no power, no
current flow.
I do not understand how shorting purple wire to ground does
anything when key is not in "Run" and not "Start." However,
when I did this, briefly, could hear a clicking from starter, but
it would not turn, then one more "touch jumper to purple wire
and ground" and starter spun and engine started. Turn key
to "off" and removed it. Engine stopped, starter continued
to turn engine.
If key was in start when purple wire shorted to ground,
seems like a fuse would blow, as it would cause a direct
short from ground through starter relay contact. Don't see
how it would have any effect on starter.
