ok second step i took i have burned the diod and after diod is burned (it actually explodes) there is no connection meaning singnal from phase dont go any further than shorted diod
but each (phase) windings have two diod when one of them is burned (no connection) the other is still working and the phase on oscilloscope is EXACLY AS YELLOW PHASE except it has both parts positive (negative part is on top)
the funny thing is that it doesnt matter which diod is burned it always showes the same effect

ok engine drives from arround 700 to 7000rpminute so that is 7000/60=116 rpssecond then it drives an alternator thru belt gear 1-4 max so we have 116x4=464 rps at alternator wich have 15-18 poles at rotor that represents that each round will generate 18 cycle/round max so 464x18=8352 cycles per second wich is herts ??
so my question to Bob how he could reach 42000hz when alterantor can get only 8352hz???
i think it may be some harmonics that he later discover but on that video he says that when he connected the boate to oscilloscope he saw 42000hz??? how ??? maybe somebody have other ideas??

i have got it
so alternator have 3 phases, each is separetly recified but in his case one of the phases rectifier went short so we got elevated sine wave
something like this
but one more thing gets me thinking if the frequency is arround 42.8khz and we want to add some harmoniocs to increase effect we sould multiply this frequency like here

i have been looking for wave form that Bob saw when testing his boat anomalies
is there any way Bob you can draw exacly what you saw on the scope when boat was going crazy??
why im asking is because if this was both diod failure is sould be "elevated" sinewave
or
if this was one diod failure it sould be "elevated" and hi or low part of sinewave
so what exacly was the that
