1989 yamaha excel 225 hp no spark to plugs
when checked with spark tester
so i started from the coils with another expert and
we got stuck when there was no output after replacing the first cdi with
a spare and removing the kill wire from the cdi box
all input voltages seem ok going into the cdi
before doing the voltage test i also performed the resistance test from
the manual all was good.
luckly i have spare parts from my old motor to learn with.
i cleand the coils brass ground surface that the screw mount threw to the bracket with a brush before i installed it for good contact .
trigger wht/red to wht/grn=2.9v
wht/blk to wht/blu=3.8v
wht/yel to wht/brn=3.0v
yes i swapped the cdi two days ago
how does the stator keep the cdi from changeing ac input
wave from being recterfied to 58v and discharge to the primary coils
it dont make sence.
but you said change the stator assy. and its doing what its suppose
to do why do you want to replace it
i dont have a bearing puller to remove
the fly wheel
yes and i am getting 85v @ low spd and 14.4 @hi spd maybe even more if the fly wheel spins faster but 50 v no way i look @ the cdi electronic spec and they say 16v
where did you gett 50v from the last expert said14v was min. from oem spec. tech has more than 5 years experience
do you have a copy of the spec or web site so i can see what you are talking about.
what do you mean voltages or ohms
i have to remove the wires to measure the ohms
you didn,t answer my question what spec are you using that tell you
50v for hi sped coil i all ready checked my coil .25pri 2500sec. 5k cap
