Tech-Tip: Basic Step by Step Instructions On How to Test a DC Gear Motor for Basic Operation
  • This is a trick we have used for more than 15 years of working with pizza oven motors. This is a quick but not thorough test of a pizza oven motor.   The PDF captures our email response (07/02/2015) to a request for help determining if a motor was faulty. The document provides a step by step response on how to test for a bad motor using a cordless drill battery -     Note: Within weeks, our step by step instructions were on another web site. 
  •  
  • Additional Note: The quickest test of a drill battery charge is to simply run the drill  (hand chucking to load ) before removing the battery. A voltmater is not a good test of the battery, if the battery is out of the drill and not connected to a load. A battery can be nearly dead and still measure the rated voltage, if the battery is not connected to a load that will create a current flow. .
