Re: FnR switch high pitch noise
NOW, Key switch ON, gear selector in FORWARD, Place the (+) probe on the battery side of the solenoid's large post (If the reading is below battery voltage, check all wiring and terminals).
50.4v which is the same as the battery pack
Place the (+) probe to the controller side of the solenoid's large post. The reading should be 0.1 to 3 volts less than battery voltage. If the reading is more than 3 volts less the battery voltage, the resistor is faulty. If the voltage is the same as the battery voltage, replace the solenoid.
47.0v. So it is 3.4v lower.
It seems that the resistor is faulty, but with the high pitch noise, I wondering if it could be something else.
