Wolf Automatic Transfer Switch (ATS)

[asteriost]

Controller board for a Wolf Automatic Transfer Switch (ATS) 6Kw.
The controller board is marked zws-ats-6cp. Printed in mirror (reverse) on the board
There are two capacitors missing. One electrolytic and one ceramic.
They are marked as c4 (ceramic) and c7 electrolytic
If anyone has a diagram or can post a picture it would be helpful.

What makes you think that they missing it could be a design change on the original design or an upgrade and they were not need for the upgrade

Look on the back side of the board dose it look like it once had solder on it or does it look like it never had solder on them and some one removed them do you know the history of this device did you buy it new or did you buy it used

The caps where blown. That is a fact. When i say missing i mean they where blown.

So if they were blown, you should have no problem to find the voltage and capacitance value of the electrolytic cap. It's printed on the sleeve on the can. If not, power it up and measure the voltage across where the caps should be and we go from there. Looks like someone had unsoldered the cap and then filled the holes with solder? Who would do some nonsense like that? That's why sam_sam_sam said why are you so sure that there is something missing if it looks like there wasn't anything there.
Post a high resolution, straight shot picture of top and bottom of the board, so we can see what's what.
