Bobcat A8032 (80-32) Fault Code: ACD/RACD Output “A” Over Current
Also shown on the panel as 80-32 · Also called ACD Output ‘A’ Overcurrent
ACD/RACD Output “A” Over Current · ai-assisted, editor-reviewed · Last updated 2026-07-13
TL;DR
Bobcat fault code A8032 (panel display 80-32) sets when the ACD/RACD controller detects too much current flowing through the Output "A" solenoid circuit, specifically the return wire at controller pin J1 A-2. When this happens the controller shuts down Output "A" to protect itself from driver damage.
Medium severity. Output "A" is disabled once the code sets, so whatever function that solenoid controls on the attachment or implement will stop working. This is not an immediate safety emergency for the base machine, but it does mean lost attachment function until the short or bad component is found and fixed.
What does Bobcat error code A8032 mean?
A8032 is set by the ACD (Attachment Control Device) or RACD (Remote Attachment Control Device) controller, which manages powered attachments on Bobcat compact equipment. The controller sends current out to Output "A" to energize a solenoid, and current returns through a dedicated return wire that terminates at controller pin J1 A-2.
When the controller senses that the current on this return path is higher than its output driver can safely handle, it trips the fault, disables Output "A", and logs A8032. This is a protective shutdown meant to prevent the driver circuit inside the controller from being damaged by excess current.
This code applies across a wide range of Bobcat excavators, skid steers, and track loaders, including the E35, E42, E45, E55, S510, S530, S550, S570, S590, S630, S650, S750, S770, T550, T590, T630, T650, T750, T770, and T870.
Common causes of A8032
- Return wire at controller pin J1 A-2 shorted to supply voltage, or shorted to the Output "A" wire at controller pin J1 B-5.
- Failed Output "A" solenoid.
- Failed ACD/RACD controller.
- Moisture, corrosion, or pushed-back pins in the ACD/RACD controller connectors, mainframe harness, attachment control harness, or the Output "A" solenoid connector.
- Intermittent fault: if the code is not active at the time of testing, the cause may not be immediately findable. Probable causes for an intermittent code include loose connections, corrosion, pushed-back pins, the controller itself, the wire harness, or some combination of these.
How to troubleshoot Bobcat A8032: first checks
- With the key switch in the run/enter position, check for the active code before disconnecting anything, since disturbing connectors can change an intermittent fault.
- Inspect the ACD/RACD controller connectors, the mainframe harness, and the attachment control harness for moisture intrusion, corrosion, or pins that have been pushed back out of their sockets.
- Check the return wire between controller pin J1 A-2 and the Output "A" solenoid for chafing, pinching, or contact with a supply voltage wire.
- Check for a short between the return wire at J1 A-2 and the Output "A" wire at J1 B-5, since a short between these two specific pins is called out as a direct cause.
- Inspect the Output "A" solenoid itself for signs of internal failure or a shorted coil.
- If no fault is found and the code was intermittent, recheck all connectors in the circuit again rather than assuming the controller is bad, since loose or corroded connections are a common intermittent cause.
How the code clears
Bobcat lists cycling the key power as the condition for clearing this code once the repair is complete. No separate reset procedure beyond a power cycle is listed for this code.

Frequently asked questions
What does Bobcat fault code A8032 mean?
It means the ACD/RACD controller detected an overcurrent condition on the Output "A" solenoid return circuit at controller pin J1 A-2, and it shut off Output "A" to protect its internal driver from damage.
What is the panel display number for A8032?
On the machine's panel it displays as 80-32.
Which Bobcat machines can show code A8032?
It applies to the E35, E42, E45, E55 excavators, the S510, S530, S550, S570, S590, S630, S650, S750, S770 skid steers, and the T550, T590, T630, T650, T750, T770, T870 track loaders, when equipped with an ACD or RACD attachment control system.
Will the attachment still work with this code active?
No. Once A8032 sets, the controller disables Output "A", so whatever attachment function is wired to that output will stop responding until the fault is fixed and the code is cleared.
How do you clear code A8032 after repair?
Cycle the key power. That is the only clearing condition listed for this code.
Why does the code come and go instead of staying on?
An intermittent A8032 usually points to a loose connection, corrosion, or a pushed-back pin somewhere in the ACD/RACD controller connectors or harness rather than a fully failed component. These faults can clear themselves when the connection happens to make good contact, then return under vibration or moisture.
Is A8032 a safety-critical code?
It is not listed as an immediate machine safety issue, but losing attachment function unexpectedly can be a safety concern depending on what the attachment is doing at the time, so it should be diagnosed before returning to normal work with that attachment.
