OhHum...
I wouldn't use vaseline, a flamable petrochemical, as a substitute for an acid cleaning product, especially on high voltage circuits. They're completely and utterly different things.
The best thing to use as flux is flux. The 'no clean' stuff is the best choice since it reduces the chance of future issues.
This is still pointing at either bad / cracked solder joints on J4... or a bad harness --- check for corrosion and continuity on the cable that goes between J4 and the logic boardView attachment 68849
Well shit
Unlikely it's the harness as i tested continuity with it unplugged on both sides. I know it's on Analog PCB because with the analog/power PCB connected to absolutely nothing. it still persists on pins 7 9 10.(Pin 7 and 9 are both continuity together since they're both ground and on the same pathway.)... I had gotten it to the point where it the ground wasn't shorting the 12volts(pin10). but when i soldered everything back exactly how it should be based on pictures it came back...This is still pointing at either bad / cracked solder joints on J4... or a bad harness --- check for corrosion and continuity on the cable that goes between J4 and the logic board
Yes but i don't think the issue is with the J4..... I mean it is. But i don't think the issue has to do with the connector or the harness. I'm very positive somewhere else on the PCB the ground is shorting/connecting to the 12volts and it's causing resistance/shorting.Have you reflowed J4?
i believe our boards are slightly different as our boards are different colours and i can't actually seem to find a C24 *unless it's been obstructed by the amount of glue they put around the capacitors* However i did find a C25 capacitor in the EXACT (based on photos) position of the one you're pointing to which had continuity between the two legs... Makes me feel like an idiot for not noticing earlier...Capacitor C24 shorted ??
No continuity found in my own board, except for two ones.
That's vertical collapse, which if I remember correctly is usually a capacitor issue, no?View attachment 68849
