What's wrong?
On the 2025 Altec Ac Series Crane and Digger Derrick, the unit adapter harness is part of the exterior lighting electrical path. Its job is to protect the chassis lighting circuit when Altec-installed body lighting or trailer lights draw power, so the circuit is not overloaded during normal operation.
On affected units, that harness was left out during assembly. Without it, the lighting load can overload the chassis circuit and cut power to the body lights or trailer lights. The added remedy harness restores that protection by carrying the load the circuit was not meant to handle alone.
The warning sign is found during a pre-trip inspection: body lights or trailer lights are not illuminated when they should be. No other warning sign is described before the lighting circuit loses power.
Who's affected?
Covers the Ac Series Crane and Digger Derrick under the same exterior-lighting harness kit.

| Units affected | 134 |
| Field incidents | NHTSA has logged no field incidents to date. |
A matching 2025 Altec model does not guarantee inclusion. Check your VIN to confirm whether your specific vehicle is included.
What's the safety risk?
Loss of body lighting or trailer lights makes the unit harder for other drivers to see and increases the risk of a crash. Check the lights during the pre-trip inspection; there is no other warning sign. Repair is free at any franchised Altec dealer.
What should I do?
- Check your VIN to confirm your 2025 Altec Ac Series Crane or Digger Derrick is included in this recall.
- Contact Altec customer service to schedule the free harness inspection and repair kit if the overload-prevention lighting harness is missing.
- Bring the recall notice if Altec has mailed one. If not, reference recall number 26V170 when you call.
- Avoid towing or night work until the harness inspection is complete, because the missing harness can cut power to body lighting or trailer lights.
