So, I borrowed a NOID lamp set from a friend. No flash on cranking.
I dropped the ECM down to unplug and check wires (who torqued those screws??). The smell got stronger so I took it out. Overpowering stench from the ECM pluf holes.
Inside, the larger electrolytic capacitor is blown - bad. Burned theough PCB and burned traces. I cannot even tell for sure what went where on the traces.
At least I have root cause now. Are there pics anywhere showing this part of the board?
Does the markup attached look like all I need to do differently with the new cap (take bottom lead up and to the right to this area)?
