yamaha 70 1995 BETO won't go above 3000 RPM

[99yam40]

Will the multimeter set on to mesure AC voltage do the job. The read value then had to be multiply by 1.42 to get the peak??

So if the value must be around 145 Vpeak by manual , then is to expect a multimeter reading of 100V

Right or not???
Only the freq of these 145 V is not known!, at least i dont know it

a good read for you

TNX

That I was looking for !!!!

Now all makes sense

Thank you , and I will try to post the readings, as soon as I measure them.

Mesurments:

Charging coil resiatance —as in service manual
Pulser coil also ok
Ignition coils —primary all ok
Secondary: all have a 4.5 kohm without the spark caps

Spark caps added on those two coils a 50kohms
Replaced the caps, now everything is as in service manual
Crank position sensor resistance ok, as manual

Lighting coil resistance, also ok.

The problem show up.

I have to get a DVA to test it on the run, and test fir input and output voltages.

I will post the readings soon.

If anyone has a hint what could it be, please help

Tnx for help

When the motor is running (idle), what is the nominal voltage when charging 14.4V ?? or lower for this motor? (messured on the battery terminals).
