Because that my friend is very dangerous on an internet forum such as this.

Nonsense. I am aware of liquid resistors used in a controlled manner..

I am not the one advocating putting a couple of wires in open seawater to create a resistor of unknown value. Who here is the dangerous one?

Don't run this test for too long as alternators are not rated for continuos duty and they over heat.

Pardon me. That sounds like cowshit.

FWIW (Not much, IMO):
The electrical resistance of water is about:
Sea water = 0.2 Ω/m (Ohms per meter)
Drinking water = 2 to 200 Ω/m
Deionized water - 180000 Ω/m
The electrical characteristics of water is usually measured by "Conductivity", which is usually measured in micro- or millisiemens per centimeter (uS/cm or mS/cm). Conductivity is formally defined as the reciprocal of resistivity.
Sea water has a conductivity of about 50 mS/cm (or 50,000 μS/cm).
