The connections that get disconnected suddenly and which could produce a spark are inside the motor case on every starter motor I’ve come across, so any spark that occurred wouldn’t be visible. That’s why the posters above are suggesting a loose connection is involved somewhere, as a spark could occur outside the case then, at the loose connection.

What does sparking mean on a motor armature?

The sparking should be mild and red/orange in colour, if blue and appears almost all around the comm, it can indicate a short circuit somewhere. The conclusive test for a armature, short etc, is an instrument called a Growler, measures voltage produced across each comm section when the armature is under test.

What to do if your engine ground is bad?

A bad engine ground is a common problem leading to hard-starting and no-starting conditions. The following test takes a voltage drop reading to locate unwanted resistance in the engine ground path. Disable the ignition or fuel system to prevent the engine from starting during your tests.
