No ;
It's a fairly loud high frequency " _CLICK_ !" .
I'd time it and _NEVER_ wait for it to click before cranking because the *instant* you hear the CLICK , the plugs begin to cool off and cold Wx. starting requires them to be glowing white hot .
Once you know how long the relay runs , cycle them once to the click then rapidly turn the key off and back on again , glow until about 10 seconds before you *know* the click will come , crank it with pedal 1/2 way down and it should roar into life almost instantly , saving wear & tear on the battery , starter motor , relays and key switches etc. , etc.
