Starter motor temperature indication systems

A system for indicating an overheated engine starter, the system comprising:

• a starter-motor housing;
• a starter motor within the starter-motor housing;
• and
• a non-reversible temperature indicator mounted to the starter-motor housing such that the temperature indicator is visible from an exterior of the starter-motor housing, wherein the temperature indicator is configured to change states in response to a temperature of the starter motor exceeding a temperature threshold;
• wherein the temperature indicator includes a substance configured to melt, break apart, or deform in response to the temperature of the starter motor exceeding the temperature threshold.

An engine startup system comprising:

• a starter motor configured to crank an engine and configured to be powered by an energy source;
• a starter relay operatively interposed between the energy source and the starter motor and configured to selectively deliver electrical power from the energy source to the starter motor;
• a solenoid coupled to the starter motor and configured to connect the starter motor to the energy source;
• a temperature sensor configured to detect a temperature of the starter motor;
• a light source integrated with the starter motor;
• and
• a controller operatively connected to the temperature sensor and the light source, wherein the controller is configured to illuminate the light source in response to the temperature of the starter motor exceeding a first temperature threshold;
• wherein the controller is configured to illuminate the light source further in response to the temperature of the starter motor exceeding a second temperature threshold, and the second temperature threshold is greater than the first temperature threshold;
• wherein the controller is configured to:
• illuminate the light source in a first color in response to the temperature of the starter motor exceeding the first temperature threshold:
• and
• illuminate the light source in a second color in response to the temperature of the starter motor exceeding the second temperature threshold, wherein the second color is different from the first color.
