HEI in Mopar ECU casing
Actually, water does NOT necessarily conduct electricity, depending on minerals, etc, "your mileage may vary." If I get time, I'll take a length of tubing and see what the resistance of some random "lengths" of local water actually are.
I was appalled, until I learned better, that power companies sometimes wash down insulators with water.
According to this:
We use demineralized water that has a resistivity of 20,000 ohm's an inch. Minimum resistivity required is 1,100 ohms an inch. Not to mention it's not a continuous stream of water but many droplets of water.
