Light Tower Fault Codes
Towable jobsite light towers from Allmand, Magnum, Wacker Neuson, and Multiquip. Most are Kubota-powered diesel gensets driving four metal-halide or LED lamps on a hydraulic or hand-cranked mast. The COMMANDER controller on Allmand units handles engine, lights, and tower deployment safety interlocks. Codes you actually see in rental yards: lamp no-strike, ballast fault, tower limit switch issues from transport bumps, and Kubota engine codes carried over from gensets.

Common Light Tower Issues
- Lamp no-strike (9) -- end-of-life metal halide bulbs after 5,000-8,000 hours
- Lamp ballast fault (8) -- moisture ingress after transport
- Tower up-limit / down-limit switch faults (10, 11) -- transport bumps
- Battery voltage low (4) -- worn battery in long-term rental yard storage
- Low oil pressure shutdown (1) -- low oil after extended jobsite runtime
- Outrigger not deployed (13) -- limit switches dirty or sensor magnet missing
- Tilt sensor out of level (12) -- mast deployed before outriggers are leveled
