Diesel generator spare parts and diagnostic tools on a workbench in a Bali workshop

Three faults cause most 'dead generator' calls in Bali: a flat or sulphated battery, a fuel filter choked by dirty diesel, and a failed AVR. Two of those three are fixed in under an hour if the right part is on the van — which is why ours carries batteries, filters, belts and the common AVR models. What I want you to take from that: do not let anyone talk you into a full overhaul over the phone, and do not start replacing parts by guesswork. A proper diagnosis is an hour of work. Guesswork is a month of invoices.

What's Included

Starting & Electrical Faults

Flat batteries, failed starter motors, corroded terminals, charging alternators, wiring faults and controller errors. We read fault codes from DeepSea, SmartGen and ComAp controllers instead of guessing.

Fuel System Repairs

Clogged filters, water in fuel, airlocks, lift pump and injection pump faults, dirty injectors. Bali's diesel quality makes this our second most common callout — we also clean tanks so the problem stops returning.

AVR & Alternator

Engine runs but no output, unstable voltage, lights flickering — usually the AVR, sometimes the alternator itself. We carry common AVR models and test output properly under load after replacement.

Cooling & Overheating

Radiator cleaning, thermostat and water pump replacement, coolant leaks, and canopy airflow problems — a soundproof box with blocked vents will overheat the healthiest engine in twenty minutes.

Note: If your genset is over ten years old and the quote climbs past 40% of replacement cost, we will tell you straight and price a replacement unit instead. After any major repair we recommend a load test — and regular maintenance to stop the next one.

How We Work

  1. WhatsApp Triage

    Send a video of the fault — the crank sound alone often narrows it to two or three causes. We tell you honestly if it is something you can check yourself first.

  2. Same-Day Callout

    Emergencies jump the queue 24/7. Most of south Bali we reach within 2–4 hours.

  3. Diagnosis

    Systematic, instrument-based fault finding — fault codes, fuel pressure, battery load test, AVR output. You get the cause and a fixed repair price before we touch a spanner.

  4. Repair On Site

    Most faults are fixed in the first visit from van stock. Bench jobs (injection pumps, alternator rewinds) go to our Denpasar workshop with a loaner option for critical sites.

  5. Proof Under Load

    No repair is finished at idle. We load the genset and show you stable voltage and frequency before we leave. 90-day warranty on the repair.

FAQ

How fast can you come for an emergency generator repair?
Same-day across south Bali — typically 2–4 hours in Canggu, Seminyak, Denpasar, Sanur and the Bukit. The emergency line runs 24/7; night callouts carry a surcharge that we state up front.
My generator runs but produces no power. What is it?
Nine times out of ten: the AVR, a tripped excitation breaker, or a failed diode bridge. All are testable in minutes and none requires an engine overhaul. Don't let anyone sell you one before testing the AVR.
Do you repair all generator brands?
Yes — Cummins, Perkins, Yanmar, Mitsubishi, FAW and the local-assembled silent units. Controller-wise we work daily with DeepSea, SmartGen and ComAp.
Why does my generator start then shut down after a few seconds?
Usually a protection shutdown: low oil pressure signal, coolant temperature sender, fuel starvation or a low-water-level switch. The controller's fault code tells the story — send us a photo of the display and we may diagnose it over WhatsApp for free.
Is the diagnosis fee really waived?
Yes — if you approve the repair, the diagnosis fee disappears from the invoice. You only pay it if you decide not to proceed.
