  1. Measure resistance of a secondary winding of the coil, having connected one wire of an ohmmeter to any of plugs of a primary winding, and the second - to big central (ВВ) to the coil plug. Compare result to the data of Specifications.
  1. Resistance measurement between positive ВВ (secondary) coil plugs.
  1. Really taking place values depending on coil temperature can differ slightly from resulted in Specifications (characteristic for temperature nearby 21 ).
  2. If the coil has not passed check, replace it.
