After experiment....A lot of smoke, but no "explosion"..

Will they be dangerous to put in then?

Hi Again. Just bought these to day. Are they ok? My local dealer said that the last black ring doesn't matter.

Jack

I will definitely use the 5 amp fuse. Thanks for all your help I've said it before and I say it again this is world class support. I will return when the new parts are mounted...
Jack

Ok, there all good. Looking forward to getting the new parts and see what it does...it will be nerve wrecking to power it up once I'm done...

Thanks all... New parts are in the post.. But what about the 4 black diods between the fuse and the capasitors? Can I measure them out and how?
Jack

The parts I need (sf163 diode) and (ndp7060 transistor) can't be bought I Denmark....sf163 I can't find anywhere and the ndp's I found is from China.........This is turning in to a thriller, and maybe I have to retire this project.

I removed all the FETs, and now I have a beeb from the meter for only short time 2 sec. I also removed the resistors and 2 of them are for sure dead. Are there also vias in all holes for fets and so on? these rings are coming of the print.

I have now ohm'ed the gate resistors, here is the result. The diode between + and - I don't where is. Is it possible to pinpoint on the photo what to change?? I'm no electronics expert but I will not give up.. All your help is absolutely amazing...Thanks
Jack

Even with the mosfet off it beeps. I didn't do the traces, just made some jumpers on the backside of the board. I also have beeps on the 3 of the capasitors

Ok, by further inspection I found this!!!! I have tried to do what you suggested, but when I use my meter on the positive and negative terminals I beeps like crazy without stops...I also didn't repair the traces, just made 2 jumpers on the backside of the print....
Jack

That was that. Today I tried to power it up and absolutely nothing happened. No light in any of the diodes. I held the wirer with my finger to the battery and it got so hot I couldn't hold it. The fuse didn't blow by the way, and then a pop noise and the smell of burned electronic came. Still no sig...

Trickyricky, thanks for your patience. I took the chance and hooked it up. It actually nearly made my 10 inch jbl gti pop out of the box, and it also drives my speakers to, so that's all good. BUT the high tone is still there, and then I found out that if I press different places on the print in the...

Pictures..

by closer inspection nothing is burned. I have located the noise to come from under the heat sink.

I didn't se where the smoke came from, and there is nothing to se. The closest is maybe from under the little bord that is upside down. I can still power it up for a few seconds till the tone starts again...Shall I power it up and just se what burns, or will it destroy everything? Thanks for your ra...

Hello Again everybody. I have just finished my zx350.....Finally. I just powered it on and the disappointment is no were to hide. It makes a high tone from somewhere inside, and suddenly a Little smoke came, cant se from where. I took my meter and put it on the beep function and it beeps for a short...

Without all your help, I would be lost. This is world class help. Thanks again.

pictures of mine zx350. Hope it helps....

WOW this is tricky. I can't get the solder to bind on to the gold trace, and I have no idea where to put the jumpers. I cant see where the traces ends caus its under some vertical circuit boards.....sorry for my incompetence....

OMG!!! this is not good. Look at the tracks on the board!! Can all this be saved???? Pictures illustrates the mess, and the new capacitors. Please I need help one more time..
Thanks

Ok, please tell me how to do this. Can it be done with a fluke like this?

New caps are has been ordered, and i'm look forward to changing them. I will also change them in my m44..
Thousand thanks for the support.
I will post a photo when i'm done.

Thank's again...
I will change the caps first,,if I can find new ones i same size as the old ones.
I live in Denmark and apparently these are hard to find here..
Thanks!!

Thank you very very much..
I have one more question about these resistors in the photo, are they bad to??
