I have a 1989 110 hp johno on which the VRO unit appeared to fail (no oil flow alarm activated) I purchased a new OMS kit as the original pump was superceded a later model was supplied . the difference was the electrics original installation was a 3 wire unit and the new one a 4 wire. All the necessary part and instructions were with the kit to convert to 4 wire.
Installation went well, how ever when running the motor with oil supply disconnected, as instructed, to test the "no oil flow alarm" the alarm is not activated.
The alarm chirps when the ignition is turned on, and works if the overheat wire is shorted to earth so I believe the alarm is ok.
Help?
