  • Start up the engine and keep it idling.
  • Disconnect the phase transformer supply leads.
  • Connect the two transformer terminals to the battery.
  • Check that, with the transformer supplied, the engine revs fall until it almost cuts out.
  • If this takes place it means that both the transformer electromagnet and the tranformer hydraulic actuator are working.
