There is a tremendous spike from the collapsing field from both starter
motor and solenoid, when it is disconnected. In fact, in a previous
discussion about an armed forces member killed by 12V (impossible), may have
been from this voltage spike. This is the same way that point type ignition
makes spark plugs spark, a collapsing field. Try holding your hand on a
starter solenoid (or take my word for it), You'll jump about 10 feet! In
addition there is likely a bunch of transient voltage spikes sent out while
the starter is running, arcing brushes look like dirty power to me.
