![]() ![]() However, here are a few potential explanations: It is always recommended to consult the wiring diagram provided in the vehicle's service manual or consult a qualified mechanic or electrician for assistance.īased on the information provided, it's difficult to determine exactly what is causing the discrepancy between the amount of refrigerant transferred and the amount of refrigerant shown in the tank. Note: This is just a possible wiring diagram and may not reflect the exact wiring configuration in your specific vehicle. Here is a possible wiring diagram based on this description:īattery positive (+) - Voltmeter (+) ' ' Battery ground (-) - Voltmeter (-) ' ' Alternator "sense" terminal - Voltmeter signal input ' ' Ignition switch "ACC" terminal - Voltmeter signal input The voltmeter also receives a signal from the ignition switch through a wire (IGN) connected to the ignition switch "ACC" terminal.The voltmeter receives the signal from the alternator through a wire (ALT) connected to the alternator "sense" terminal.The voltmeter is grounded through a ground wire (GND) connected to the chassis.The voltmeter gets power from the battery through a 5A fuse (F2) and a 10A circuit breaker (CB7).Here is a possible wiring diagram for the voltmeter on a 1996 Peterbilt 379 with a C15 engine: If none of the above steps resolve the issue, it may indicate a problem with the internal circuits of the multimeter, and it may need to be repaired or replaced. Reset the multimeter: Reset the multimeter to its default settings to see if this resolves the issue.Check the settings: Make sure that you have selected the appropriate range and function on the multimeter for the measurement you are trying to take.Check the batteries to ensure they are properly installed and have sufficient charge. Check the batteries: A weak or dead battery can affect the accuracy of your multimeter readings.Try using a different set of leads to see if the issue persists. Make sure there are no breaks or cuts in the leads. Check the leads: Ensure that the leads are properly connected to the multimeter and the test points.Here are some steps you can take to troubleshoot the issue: If your Fluke 21 III multimeter is not reading AC or DC voltage properly and the ohms sign comes on in voltage mode, it may indicate a problem with the internal circuits of the multimeter or the leads. You can also refer to the manufacturer's instructions for specific calibration procedures for your Super Pro moisture meter. ![]() It's important to note that different types of maize can have different calibration requirements, so it's a good idea to recalibrate your moisture meter regularly and for different types of maize samples.
