  • Optimax Air Injectors

    Smartcraft came up with "Injector Fault" and motor lost power while cruising. Found the dead cylinder by unplugging the fuel injectors and noting any rpm change. I then swopped two of the fuel injectors. Result was, problem stayed with same cylinder.
    I came up with checking the air injectors with a 9 volt battery at the terminals. The two good cylinders produce a loud clicking at every wire tap to the terminals. The bad cylinder only made clicking every few taps of the wires to the terminals at first, and then less and less often. I went right back to a good cylinder it insure the battery was not loosing power. Is this sufficient evidence to replace the air injector? Thank You

    It should click every time, although Mercury computer diagnostic is best way to diagnose injector, that injector is probably bad.

      My troubleshooting proved valid. i picked up a used injector and installed it. Motor runs like new. Thanks for the input.
