generator voltage is too high ? any propositions? Answered

i have a generator, that has an exciter capacitor. the capacitor is dead and nothing as usual was written on it? i changed the capacitor by another one (45 microfarad) but the voltage was too high, i tried then 25 microfarad yet it still too high ? nearly the same (264 V) or a little bit less.  any propositions?

hey,
thank you for the fast reply.
yes iam trying to get 220 - 230 volts max.
the capacitor is electrolytic one of value to be decided, and handles more than 400 V normally to get the 220 V output.

but lets explain more, in fact without the capacitor connected, the generator turns on but no output voltage at all.

i passed to YANMAR site, and normally all their generators use condensor type regulators, so i guess it is this one.

thanks again guys,

What are you trying to get ?

If it's for a "kick-up" or sorts I'd say that it needs more capacity than that.

Smaller caps should make for smaller voltages. What kind of cap are you using? Is your goal 240 volts?

sorry, its a condensor type regulation generator,, so the capacitor regulates the output. so, i guess i should decrease my values more ? no ?
