TL;DR
Bobcat fault code A8332 (panel display 83-32) sets when the ACD/RACD controller detects too much current flowing through the Output "D" solenoid return circuit at controller pin J1 A-27. The controller shuts down Output "D" to protect its internal driver from damage.
Medium severity. The controller disables Output "D" as soon as it detects the overcurrent condition, so the attachment function tied to that output stops working. This is not an immediate machine-damage event by itself, but running an attachment with a disabled output can create unexpected behavior, so it should be diagnosed before returning to normal work.
What does Bobcat error code A8332 mean?
A8332 is an overcurrent fault on the ACD/RACD (Advanced Control Device / Remote Advanced Control Device) controller's Output "D" circuit. This output drives a solenoid, typically for an attachment function, through a return wire that connects at controller pin J1 A-27.
When the controller senses that the current flowing through this return path is higher than its output driver can safely handle, it disables Output "D" immediately to prevent damage to the internal driver circuitry. That means whatever attachment function depended on Output "D" will stop functioning until the fault is cleared and the root cause is fixed.
This is an electrical protection fault, not a mechanical failure of the attachment itself, though a shorted or failing solenoid can be the root cause.
Common causes of A8332
- Return wire at controller pin J1 A-27 shorted to supply voltage, or shorted to the Output "D" wire at controller pin J1 B-25
- A faulty Output "D" solenoid drawing excess current or creating an internal short
- A fault inside the ACD/RACD controller itself
- Moisture, corrosion, or pushed-back pins in the ACD/RACD controller connectors, the mainframe harness, the attachment control harness, or the Output "D" solenoid connector
- An intermittent condition: if the fault is not present at the time of testing, the exact cause may not be identifiable right away. Loose connections, corrosion, pushed-back pins, the controller, or the wire harness (alone or in combination) are all possible contributors
How to troubleshoot Bobcat A8332: first checks
- With the key switch in run/enter, check for stored or active codes to confirm A8332 is currently present, since the fault may be intermittent
- Inspect the Output "D" solenoid connector and the ACD/RACD controller connectors for moisture, corrosion, or pins that have been pushed back out of their sockets
- Check the return wire at controller pin J1 A-27 for a short to supply voltage or a short to the Output "D" wire at controller pin J1 B-25, tracing the mainframe harness and attachment control harness along the way
- Test the Output "D" solenoid itself for an internal short or excessive current draw, disconnecting it from the harness to isolate the solenoid from the wiring
- If no fault is found with the key on and the code will not reset, treat it as intermittent and focus on connector condition, harness rubbing points, and pin retention rather than assuming the controller is bad
How the code clears
Once the repair is complete, cycle the key switch power off and back on. No separate clearing procedure or reset sequence is listed beyond cycling power.

Frequently asked questions
What does Bobcat code A8332 mean?
It means the ACD/RACD controller detected too much current flowing through the Output "D" solenoid return circuit at controller pin J1 A-27, more than the output driver can safely handle, so the controller disabled Output "D".
Will my attachment stop working with code A8332 active?
Yes. As soon as the controller sets this code, it disables Output "D", so whatever attachment function is wired to that output will not operate until the fault is fixed and the code is cleared.
How do I clear code A8332 after fixing it?
Cycle the key switch power off and back on. That is the only clearing step listed for this code.
What is the difference between A8332 and A8305 or A8306?
A8305 is a short-to-battery fault and A8306 is a short-to-ground fault on the same Output "D" circuit, both of which describe a specific direction of electrical fault. A8332 is different: it is an overcurrent condition, meaning too much current is flowing through the return path, which can be caused by a short to supply voltage or a short to Output "D" itself, a bad solenoid, or a controller fault, rather than a simple short to one particular reference.
How is A8332 different from A8307, the Output "D" open circuit code?
A8307 sets when the controller sees no continuity or current on the Output "D" circuit, which points to a break in the wire or a lost connection. A8332 is the opposite type of problem: the controller sees too much current, not too little, so the checks focus on shorts and solenoid or controller faults rather than open wires.
Can a bad solenoid alone cause A8332?
Yes. Bobcat lists the Output "D" solenoid itself as a possible cause, since an internal short or fault in the solenoid can draw excessive current through the return circuit even if the wiring is fine.
Why can't I find the cause of A8332 when I test the machine?
If the fault is intermittent and not present at the time of testing, the exact cause may not show up right away. Loose connections, corrosion, pushed-back pins, the controller, or the harness can all cause intermittent overcurrent conditions, so a careful visual and mechanical inspection of connectors and harness routing is often needed even when the fault is not actively out.
