A failed oil-pressure switch, temperature sender, drive lube monitor, harness connection, ignition switch feed, or ground fault can mimic a bad alarm buzzer.\u003c\/p\u003e\n\u003cp\u003eInstall the kit using the correct factory wiring connections. Do not bypass the warning alarm or leave the engine in service with a disabled alert system.
