No-Load Test

  1. Clamp starter to test bench or in vise. Set up test equipment. See Fig 1. Close switch to engage starter. Measure current draw, rotating speed and voltage drop. See NIPPONDENSO STARTER SPECIFICATIONS  table.
  2. Low rotating speed or excessive current draw may be caused by high friction rotating resistance caused by worn bushings or improper assembly.
