Idle Stabilizer Check

  1. If engine will not start, check idle stabilizer first. Remove both connectors from idle stabilizer, and connect them together. See Fig 1. This by-passes the idle stabilizer, connecting the Hall control unit directly to the distributor's Hall generator.

    By-pass gray impedance transformer in same manner as an idle stabilizer. 

    NOTE: On models equipped with an impedance transformer, testing procedures are performed in same manner as with an idle stabilizer.
  2. If engine now starts, check contacts and sleeves in idle stabilizer connectors for correct location or for damage. If OK, install new idle stabilizer. If engine would not start with idle stabilizer by-passed, proceed to Distributor Voltage Supply Check.
