My p72 board is damaged at the C27 capacitor.
When I got it chipped the guy said he fixed it but it threw the 0 cel and burnt the board more after I drove it.


I want to solder the capacitor to different points since the traces are damaged but I cant see which trace the + connected to.

If anyone has a diagram of the traces for a manual P72 jdm OBD1 ecu or a picture of the board underneath C27 that would be a big help.

Thanks

Someone must know which trace the + part of the capacitor shoud connect to?

 

should be able to find a photo if you google the specific p72 that you have.

 

The problem is that the capacitor normally sits right against the board so you cant see which trace it connects to from a photo

 

what we would do is desolder the bad ccapacitor and clean the area with a q tip and alcohol. use a bright flashlight on the underside to trace the tracks.

 

The capacitor in the photo is not the original and i have actually cleaned it a bit. The track is completely burnt away at the point where it did connect so there is no way of seeing which one of the two strips it actually connected to.

I am thinking that bottom terminal should connect to the bottom right trace and not the bottom left trace.Can anyone confirm this?
Could i just solder it to that leg of the component on the same trace?
