I have read older threads re ox 66 2.7l, where when an entire bank (starboard) of cylinders is losing spark, I understand, that it is most likely (99% of the time)the stator.
I believe this is the problem with my 1999 200HP 0x66 EFI (sx200txrx).
At higher rpm, most of the time does not exhibit the problem, but after *****ing rmp 1500 or so it will exhibit intermittent , or weak spark on the 1,3,&5 cylinders. It will also exhibit the problem at lower rpm after backing down from *****ing RPM to Idle RPM.
I am confident it is the Stator, based on the searched threads I have read, I do have some questions and confirmations, please;
Should this motor continue to run if I disconnect the Positive cable from the battery? Wht shoudl I expect to happen on this engine, if I disconnected the positive, while it was running, if it were not having any issues?
I believe it is still charging the battery(tested battery), however the motor dies within 20-30 seconds of disconnecting the positibe battery terminal. Does this give us any clues?
Also, does this engine have the CCS? where it runs on less than 6 cyl below 2000, 800, RPM? I ask becuase at Idle the spark is weaker on some cyl than others. If so which coils do not fire or produce weak fire, at the respective RPM?
I also checked spark strenght with a tester at 1800 RPM, it will jump at least 1&1/4 inches with a tenacious snap on the Port Bank, on the Starboard bank at the same RPM it will jump about 3/4 to 1" on the starboard bank and the snap is not as loud.
I have asked questions and provided information as to avoid a volley of back and forth and to TRY to avoid further questions, but would like to be sure before droping the significant coin on the Stator Coil.
Much Thanks in advance!
