So I start up my car today and I remebered that I left my wallet inside. I go back inside, and when I come out, it sounds like there is some electrical popping coming from underneath the hood (or bonnet). I run for the ignition and quickly turn off the car. I pop the hood (or bonnet) to see if any damage has occcured. There were a few more pops after shutting off the engine, but nothing visually seemed wrong. I restarted the car and the popping started again. I looked around the engine, and I noticed black flakes shooting from underneath the heat shield. After a few more seconds, the popping stopped alltogether, but there were a bunch of those black flakes laying on the ground. Anybody know what this was? It had been raining pretty hard that morning too.
