As famous previously, substantial resistance within an electrical circuit lessens the level of voltage downstream of The purpose of substantial resistance. A lot less voltage into the motor means the motor makes significantly less electricity. Basically checking for voltage With all the fuel pump disconnected isn't going to let you know when there is any resistance during the circuit since the resistance only causes the voltage fall though the circuit is Doing work.
