Method 2: Jump-start the clutch. The process is a bit different for older cars that are not compatible with the R134a type. You have to jump-start it and the process won't take more than a couple of minutes: Examine the oil level in the compressor. Add oil if the level is below the normal point.In this step, you have to detach the connector cable from clutch oil. Keep it safely away from all other components. Use a digital voltmeter to measure the ground and voltage of the battery at the detached connector cable. Go on to check the fuse if you cannot read the voltage readings. Move on to the clutch relay if the fuse turns out fine.Off and on power to AC compressor. 2011 freightliner cascadia dd13. Everything is brand new - Answered by a verified Technician. ...

You can also do an A/C clutch coil resistance test using an Ohmmeter. The clutch coil should have a range between 2 to 5 Ohms. If you get a reading lower than 2 Ohms or beyond the 5 Ohms, this is indicative of a bad coil. If your reading is 0.00, then, most probably, there is a short circuit in the windings. sam's club on alpine Diagnostic Trouble Code (DTC) P0480 stands for "Fan 1 Control Circuit.".
