TS, double posting ka for same topic... Sinagot ko na tanong mo sa kabilang thread mo... Correction lang, ang detection ng init by your CDI unit through thermostat sa makina will not cause fan to engage, iikot lang yan if the engine is "beyond" its' normal engine temparature during operation... If engine is at overheating risk, turning off your engine then turning only the "ignition on" will also cause the fan to engage even if engine isnt' crank'ed up yet...
