Unless the engine had a 'running' sensor.. like a cam sensor or something... and used that 'conditional' scheme to supress the horn blowing with 0 oil pressure, while there was 0 cam movement.. but then.. I don't get the idea that these chineese machines went to that much trouble.. /forums/images/graemlins/grin.gif
( of course i guess it could be using the alternator 'charge state' as a way of determining if the engine was runing.
I've made analog logic circuits like that for 'project' on my old gas jobs that used the armature as a reference voltage to determine if the engine was running, with respect to the state of the ignition switch. The armature on those genny setups was isolated from the battery via a cutout relay in the VR, when the engine wasn't running.. so it was a fairly good scheme.. unless your fan belt died, or the genny died.. course.. you should KNOW if your fan isn't going, or if your ammeter is reading a discharge anyway.. )
