Sir Mark34 . . . . . . .
Hoping that your English to Romanian translation skills are now working flawlessly . . . .
Well here goes. . . I will tell you what I think that I sees . . . and then you feed back what you see . . . and think that you saw, that you thought that you would think as being what I should have seen.
Looks like we have a battery capability of a series of cells, all strung together to output up to 12 VDC.
Looks like the left GREEN terminal strip is supporting the build of a blocking oscillator.circuit.
It is utilizing one small signal transistor , one resistor, one step up transformer /wound on a ferrite bobbin core .
The transformer secondary outputs its upped high voltage output into one rectifier diode that then passes up
and dumps its cathode lead to the + of your electrolytic storage capacitor
Now on the right terminal strips 4 screw connectors, just about all there is being a mystery.
Excluding that right bottom terminal . . . . . which is common power negative ground.
It receives your battery pack ground, and your Digital Panel Meter common .
HOPING that panel meter has its series range divider resistors to be able to read up to 500 volts DC with its YELLOW lead..
Also, the right terminal strips top right connection is having the digital panel meter + connection, and being the high voltage connection which feeds into the + of the electrolytic storage capacitor.
NOW the weirdness fully onsets with the last connection to that same top connector also connecting to what looks like a larger R1 resistor that is going down to the 2nd terminal and there to connect to yet another smaller R2 resistor in series to ground.
That added series resistance , would be pulling that available supply voltage down, all in accordance of them not being on up into the megohm ranges.
Furthering the mystery is what looks like a D-pak surface mount power transistor of the TO-220 family with three attached flying wire leads .
The top collector tab wire ? goes up to a dormant screw connector, at the second screw position down.
Another lead (Base or emitter in accordance to the front/back orientated view of the transistor.) goes to common ground. . . .only emitter connectivity makes any sense.
The third connection is going to a momentary contact ORANGE "tact" switch that would momentarily make a connect to the 12VDC supply.
That makes no sense in that connection going to either a base or emitter.
That lastly leaves the YELLOW momentary contact "tact" switch that would momentarily transfer the 12VDC battery pack supply to the top left screw connector of the left terminal strip.
BUT that THEN leaves the mystery RED wire on that terminal exiting top left and going into hiding, unless it is looping back and coming down, and thereby effectively bypassing the YELLOW tact switch, to have that HV oscillator circuitry activated at all times, if there is being a 12VDC presence.
TEST PROCEDURE:
Lift the POSITIVE / cathode / banded diode lead completely away from right terminal block- top connection and connect it to a paper / polyester or disc ceramic capacitor with a break down voltage of of greater than 400.
VDC breakdown rating . . . minimum of 0.1 ufd capacitance and ground the other lead of that capacitor.
Utilize the LOW loading that a common DVM will provide and set it to DC Voltage function and scaled to a range of 500VDC.
Fire up the unit and THEN you will be able to see exactly the max DC voltage that unit will be able to supply.
THEN you will have to further deal with the hidden leakage resistance in that electrolytic that you are wanting to use and how FAST it will then be able to charge up IF-IF-IF-IF-IF its even being able to overcome the electrolytics internal leakage.
Back when we noted that larger R1 resistor ? of the series pair, if that just happens to be a DIODE, instead , its being wired in wrong, with its cathode needing to go back to the anode of the existing small HV rectifier diode and a 0.1 ufd capacitor inserted between its anode and ground . THEN you would have yourself a voltage DOUBLER circuit . . . . .BUT still, possibly with not enough OOOOOPH to overcome that electrolytics internal leakage.
FINALLY . . . . . . just exactly WHY do we need a 1000 ufd capacitor charged up to a 350VDC level ?
And whats a RISS bay . . . . . .does it have anything to do with those racy photos that are on your image storage support site ?
