Spn-876 compressor clutch circuit.
pacawallop. The diode you found in the a/c clutch circuit is a spike-suppression diode, attached to the compressor clutch terminals to eliminate the potentially damaging voltage spikes that occur each time power is removed from the compressor clutch and the clutch opens. If there were no diode in the circuit, these voltage spikes could travel ...

A/C clutch rubber blew out on my last a/c compressor so I replaced the compressor and had the system recharged. Now the clutch will start spinning when a/c is turned on but wont engage the compressor. I don't hear the click sound when an a/c usually engages. no leaks in system and had recharged by shop.
There are two other "right out of the box" clutch issues that are encountered with some regularity on tech line calls. These are: 1. No clutch function at all. (Usually due to an "open" clutch coil.) 2. The A/C compressor clutch circuit blowing fuses. (Usually due to clutch coil resistance being too low.) As a result, it is advisable to ...

Identifying the Types of Noises. Pinpointing the specific type of noise your AC compressor makes when the clutch engages is crucial to diagnosing the issue: Squealing: This high-pitched noise often suggests a belt issue. The belt may be old and stretched, causing it to slip on the pulleys. It can also indicate misalignment or a lack of tension.

In those cases, a higher CFM (37.4) compressor is available for aftermarket purchase (customer pay) or as an option in ...
That fault SA 25 spn 876 is for your compressor clutch. The clutch on your AC compressor has a return voltage too low. I recommend either replacing the clutch or the whole AC compressor. Sometimes the wire harness will cause the low voltage, but it is more common to have the clutch burn out behind the locking plate on those Cascadia trucks.1. Slipping Clutch of A/C Compressor. A slipping clutch plate can be the most common cause of AC clutch engaging and disengaging intermittently. A slipping clutch is a sign of severe wear or an increased gap between the friction plate and compressor pulley. Clutch plates and pulleys are designed to fit snugly together.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 …2015 cascadia gb6305 The one highlighted in blue the other codes are from when freightliner installed my windows wrong Compressor clutch circuit data valid but below operational rangeAnd j1939 engine one Voltage above ...

DTC P0745 sets when the PCM or TCM has detected an abnormality in the electronic pressure control solenoid circuit. Computer controlled automatic transmissions use variable amounts of hydraulic pressure to provide shifting and TCC (torque converter clutch) operation. What are the common causes of code P0740 ?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 ...SPN-641 9 Engine Variable Geometry Turbocharger Actuator #1 Engine 1 Jun 24, 5:06 PM Jun 24, 5:06 PM Intermittent Closed SPN-876 1 Compressor Clutch Circuit Passenger Operator Climate Control 1 Jun 24, 9:52 AM Jun 24, 9:52 AM Intermittent Closed SPN-523318 7 Passenger Operator Climate Control 1 Jun 18, 12:18 PM Jun 18, 12:18 …520465.
