GPL Starter Motor Amp Draw

This notebook page for GPL Starter Motor amp draw.

Amps are measured using a Craftsman Amp Clamp (the red one).  Location is line between the solenoid and the starter motor....closer to the starter motor.

Using an identical battery (LiFePO4) lithium and identical engines.  One starter motor was over 5 years and the other was brand new.

A new starter pulls 146 amps.

The older starter pulled 169 amps.

Although I have not confirmed this, I am assuming that the commutation strips on the older starter will have a layer of carbon material that has worn off of the brushes.  This "could" explain the higher amp draw.
