Hi Gyula

Thanks for your very good advice.
I checked my schottky diode they work OK but i decided to change against a stronger bridge rectifier (i don't know the datas)

but the trace at the bridge output is really impressive , spikes up to 272 volts (pix 1). I could easily and shortly charge a 22micro F 400 volt electrolitic cap to 230 volts.

An than i tried to put a neon bulb across a 2000volts 1 F and it light very good and than i put the neon bulb direct on the bridge (pix 2)

than i reconnected the bridge to the circuit and here the trace , the battery is my old 4.5 volt alcaline batt which is now at 4.18 volt (pix 3)

I make a long run test now

@Futuristic

keep us informed of progress thanks

Hi Laurent,

Thanks for the infos, very interesting. 
I would not use but for temporary test the stronger diode bridge because its is most likely designed for 50-400Hz frequency and also the forward voltage drop may be excessive.  Now it is good of course, once you have those bigger peak voltages coming from the coils.
Do you use a series resistor via the reeds from the battery when the reeds energize the series -++--++- coils? If yes, how many Ohms?
Could you check that if you place a more decent load across the 22 microF capacitor, then it increases the current consumption from the battery? On a decent load I mean a 5-6 or 10 kiloOhm resistor, and assume then the 230V will go down from the capacitor to a few volts? If so, then what does  some hundred Ohms load to the cap voltage and current consumption from the battery?  Sorry, just curious...
You wrote a 2000V 1F capacitor, is it really 1F, I wonder, a typo?

rgds, Gyula

"Hey Congs how long have you run them? I have found that some batteries have dropped before they rise. Great rotor! Also what is the polarity of your coils? Mine is -++--++- . For me a smaller rotor allows me to adjust the coils so they have more influence on rotation. Where to you have your reeds? I didn't see voltages rise or have an indefinite runner (switched off after 97.5 hours) until I bought a scope & followed Ossies advice about shortening the activation pulse"
- Running so far, but with the voltage drop (.03/24hrs).
Polarity - all same poles are outwards, i believe it's optimal, otherwise they will work against fields in coils.
RS from local electronic shop, but they are low voltage, easy to weld; looking for a good ones, hi-power, say up to 3A, they do not make them higher amperage.
So, do you have voltage rise on THE running bttry?
Thks.
cheers
