Problem of the Day: No Start. WTF?

[StephenVA]

I missed your post about everything works except the starter does not spin. Starter itself or the relay. Testing the voltages at the starter and jumping the starter are the only true tests. The reset mentioned above (Battery cables) is like a reboot for your home computer. The crossing of the battery cables (AFTER removing them from the Battery) removes all the stored energy everywhere in the circuits.

Trick: Tap on the starter with a mallet with key in the start position, yes you need two people. At times when they go bad they find a dead spot on the winding/armature and need a twist to find a good spot for the brushes to connect. As everything wears the brushes are weaker as the materials wear, carbon spots, etc.

Just double check battery voltage before starting;
