Spn-876 compressor clutch circuit.
The compressor clutch should ahve a good ground through the mounting bolts. The single lead going into the clutch electrical plug receives power from the compressor clutch relay. The relay should ahve power coming into it on 2 teerminals; one should be hot at all times, and one should have power only with the key in the run position.
One of the reasons why compressors do not engage is because of a low pressure lockout, a poor ground, a bad clutch coil, an opening in the wire to the clutch coil, or simply a blown fuse. There are several ways A/C compressor clutches receive power. One, the relay can be operated by the PCM (the PCM interprets the condition of the low and high ...In this video, young mechanic Aiman will give you ideas and show you how to jump start or manually engaged your AC Compressor Clutch in your car and bypassin...Hello, I'm having a issue my freightliner cascadia(###) ###-####keep throwing code than turns off the are spn 876 fml 11 and spn 4765. ... compressor clutch circuit number 876 dated valid but below normal operation range replace the compressor expansion valve and dryer charged it still has code there's another code in it to HVAC …Thanks for the update. That fall code is directly related to your AC compressor clutch problem. The ground comes from and through the ECM and controllers. The controllers will connect ground through its inputs and outputs even for fan functions as well taking the place of a relay in the circuit in a lot of cases.Clutch Temperature Message: This issue may be induced by “two-footing” the service brake and accelerator pedal simultaneously causing the clutch not to fully close, inducing a …

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.
A/C Clutch Relay. The air conditioning electronic control module can control a high-current component like the compressor clutch by applying a low current to the circuit's relay. Electromechanical relays use a coil that controls contacts or an arm that swings between two contacts. When the relay is open, the compressor's clutch is disengaged ...

Retired service manager, member of Solihull Society, SCLR, NCLR and the Santa Barbara 4Wheelers clubs.Resistance Test: Perform an A/C clutch coil resistance test with an Ohmmeter. Typically, a clutch coil should be between 2 and 5 Ohms, and any reading below 2 Ohms or over 5 Ohms indicates a bad coil. A reading of 0.00 indicates that there is a shortage in the windings. A reading of O.L. or infinity indicates an opening in the windings.Active SAM Cabin A/C Compressor Clutch Circuit - Amperage Below Normal/Open Circuit SPN 522006 5 1 Inactive SAM Cabin Left low beam Circuit - Amperage Below Normal / Open Circuit SPN 521905 5 1 ...
