What's wrong?
In the 2021-2025 Altec Digger Derrick and Am Series Aerial Device trucks, the Altec power distribution module is an electrical junction that routes power to body equipment and related circuits. The missing part is a diode, a one-way electrical gate that keeps current from flowing back into the wrong circuit.
On affected vehicles, that diode is missing. Without it, 12-volt power at the Altec power distribution module can backfeed into the chassis ignition circuit when the ground is disconnected and reconnected during battery replacement or other maintenance. That backfeed can start the chassis engine even when the key is not in the ignition. The remedy adds the diode so voltage cannot feed back onto the ignition circuit.
There is no warning sign before the engine starts unintentionally. The issue shows up during battery work or similar maintenance, so unexpected electrical activity around the battery or ignition circuit is a reason to stop work and have the unit inspected.
