I am working on a car and it has a fault which occurs when it gets to temprature.
Anyway, I got the ECU stripped and found a spot that looks overheated or maybe just prolonged heat has created a spot that I am concerned about?
I first scraped back all the raised area thinking it was the copper tracks that had blown but they all seem intact. The Diode to the area looks to be the culprit.
Does this mean the diode is faulty? I have a good multimeter and it reads the same ohms in both directions does this mean it is faulty? I know its a different type of diode so not sure quite how to test them.
I am no expert just learning, I used a Mac tools EM710 to test in ohms position.
If faulty how can I get an identical part?
Many thanks
