Let's bring this one to the table again.
I have been stuggling with this for some days again and i found out that when i did some measurings with voltagemeter, i got even more confused.
In the relaybox beside the battery, there is a square coupling that has only one wire on it(blue/black) and thats the wire that goes to the pump.
I gave direct 12v from the battery to that wire and the pump turned on.
So then i measured the voltage coming to that wire from somewhere, i have no clue where, and as i put the minus cable from the voltagemeter to the batterys minus and the meters plus cable to the wire coming from somewhere it had no voltage, but then i put minus cable of the voltagemeter to the plus side of the battery, it showed 11.7v....
Why? Is there a short circuit or what?
My explaining isn't very clear to understand but please ask more from me and help me with this.
