Found that my 90 amp fuse on Mercruiser I/O 5.0 liter was blown which led me to suspect a short somewhere. Found a great troubleshooting process on this website. Disconnect positive battery lead, turn off all load at switches, connect voltmeter to positive cable then to positive post of battery. Read voltage, if any voltage your have a short. Move on by isolating each circuit to see if any voltage is present. if you have voltage move on to next circuit, if no voltage you have isolated the problems circuit.
Now we come to my question. Did all of the above, had voltage thus a short somewhere. Disconnected individual circuits did not get voltage drop, disconnected all grounds to battery, repeated measurement still show voltage even though ground is disconnected. How can this happen and what does this indicate?
