I believe somebody commented that starters are not polarity
sensitive. I'm just a novice backyard auto mechanic, but as
an electrical engineer, I believe all DC motors are polarity
sensitive. If your starter is turning backwards, it may still
be managing to start the engine. I had a weird experience
with a two-cycle Saab 96, where I had the two spark plug
wires reversed. This reversed the firing order and and the
engine actually started up backwards! In reverse the car
went forward and vice versa.
Does anyone remember the thread about changing
battery polarity? Didn't something have to be done to
the starter?
