This ones maybe?

Hi Gc339

I have now tested the ZD02 as in the diagram abowe.
I have 17,18V in my to batterys.



And when the Zener diode is connected it drops to 14,1V
So it must be a 13V Zener.. i do do not seems to find any 14V zener diode on ebay?

HI

Thanks for claifying the items.

The D5, the 1SS118 I have orderd some on ebay http://www.ebay.co.uk/itm/182455364389?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT - then i jusy need to wait

Regarding the ZD1, 13Z - if i order some of theese 13V here..  http://www.ebay.co.uk/itm/121782360886?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT

If i check a 16Y zener (as referenze) in this catalog it's a 16V zener.. so i think but i am not sure that a 13Z is a 13V?

And if they are the wrong one's would they burn up if it is the wrong component?

Hi Gc339

Sorry for the delay but I did not have any spare time this weekend to test the components.
But now i have tested the components and there might be two who is defective

D5 - I have tested the diode in citcut and i get 0000V (in diode mode test - both ways), if i test in conecticvity i get a short.
ZD1 - the same result, if i test in circut i get 0000V (in diode mode test - both ways) if i test in conecticvity i get a short.

If i am correct the D5 and ZD1 is defective, correct? - if so i need to figure out where to get that componets on ebay..

If i look D5 up in your chart it is a S118? what is that?
And ZD1 is 13Z, how to find them?

The ZD1 is this the one? http://www.ebay.co.uk/itm/121782360886?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT

Note..As a diode reference in circut i have also tested D6+D7 also in citcut i get 0,514V when black test lead to black on diode, and OL the other way - so thats reads correct.

All the other tested components reads OK according to your component chart (tested out of circut in china tester)

R25= 10,24k
R23=179,8k
C15= 10,4 uf esr=170ohm
R22=46,5k
R28=4,7
R28=2,4
R26= No component
R24= 220
R21a= 69,9
R21b=68,7
Zd2= Diode uf=719mv C028pf
D6= Black test lead on black stripe on component - 0,514v - reverse leads OL
D7= Black test lead on black stripe on component - 0,514v - reverse leads OL
D5= Short (tested in Circut)
Zd1= Short (tested in circut)

Hi GC339

No i have not yet tested them all - I will have the components de-soldred to night and test them in my china tester
I will let you know the result

Kind regards

HI G339

No problem

I have de-soldred the D11 also - and messured it too, it reads in tester:  diode Uf=581 mv c=11pf

switched power on at the pcb, and put the test probes at the fan outlet,no 12V present :(

I have double checked the Q1 a K1535 it checks OK in the tester:


Also checked the Q2 a C1627A .. but in the component cart is ony a C1627..no "A" DO I have put in the wrong component..? when i check it:

Hi

Just a quick question, regarding the de soldering..

The D1 diode, thats the bridge rectifier, are you sure that one of them i need to de-solder? if i de-solder one leg, will i not loose the power? i case witch leg?

I have de-soldered the following diodes at tested them in the china tester
D9 Tests as diode uf=575mv c=12pf
D10 Tests as diode uf= 580mv c= 11pf
D3 Tests as diode uf=585mv c=15pf

With the D9,D10 and D3 de solder still no 12V at fan outlet - but i gess that might be due to D1.. but i am not sure witch leg to de solder.

HI

I just tested with the other leg of R24 - also 328V present at both the blue circled marked test points.
Then the R24 might be good? it is also brand new

I have to try out the de soldering of one leg of D1,D3,D9 and D10. to see if thats give me 12V - then take it from there i guess..

Kind Regards

Hi GC339

Just a quick update

I have measured between R24 and both of the blue circled test-points.
I have 328V in to the L2 transformer.


I have to go to work early tomorrow,so no more testing tonight...but tomorow i will test R24 and de solder one leg of D1,D3,D9 and D10. to see if thats give me 12V

HI

OK, thats funny.. when i looked at the items i had changed.. I looked at R24 and not R4, and where also planning to check R24
But anyway.. ill check it, thanks for the update

HI 

Regarding the R4 - i previously have replaced it with a new resistor, so i shroud be OK - but ill de-solder it and test it, just to be sure

I'll also try to test test input of the L2 by leg of R4 and one of the blue marked points and let you know what reading i get.

And also try the de-solder one leg of D1,D3,D9 and D10. to see if thats give me 12V

Thanks again

Hi GC339

Sorry for the late answer to your post.

I do not know if it helps, I have tried to measure if there is any volt present at the input of the L2 transformer. (I guess that's the input)

I have messured 0V at the two marked test points below at the back at the PCB.




And so far i have tested:
Q1 = Checks OK
Q2 = Checks OK
D4 = Checks OK (0.470 ohm one way and OL other way)

Hi and good evening..

So now finally the new transistors for R1 and R2 arrived.
I have soldered them in, now i got 320 DC Volt  a step in the right direction at last .



BUT still no 12V or 5V present... dammit! 

Have i overlooked something...?
- Must i de-solder the L2 transformer one more time and test it now i have fixed my tester.. or is there some other component.

HELP!

Hi

Yes its strange, but i think you explanation is corect  - its so exiting to get the new resistors and mount them 
I have ordered them in UK this time, so hopefully i get them at the end of next week.

If i had placed an order in china i'll have to wait a month before i get them and the diffrence where that i coud get 15 resistores instad of 5 for the same price - but i only need 2 for this project.

(I have two more powersupplys for the g-loc who also are dead, but i only need this one to work them i have two working for my G-loc)

Kind regards
Per

Hi

Just an update.

Regarding the R1 and R2 resistors - I have de solder them and they are dead! - so you naild it GC339 



I just have ordered 5pcs of 5W 1.2 Ohm at ebay

http://www.ebay.co.uk/itm/162137410017?_trksid=p2060353.m2749.l2649&var=461108678563&ssPageName=STRK%3AMEBIDX%3AIT

Hopefully they will arrive soon

Hi GC339 

Thanks for your reply 

1. The mains voltage coming out of the socket here in Denmark is abaut 230V AC.
I will check the voltage at the "wavy lines" on  bridge rectifier and let you know what that measures.

2. I have not checked the R1 and R2
I will de solder them and measure them and let you know the result

3. I will also try to measure the voltage between the C8 and C9 terminals and let you know.

A huge thanks one more time - now i have some steps to preform and get a bit closer
