Power Generator Service and Repair in Berlin

Preventative servicing, load testing, AVR voltage regulation, and mechanical overhauls for petrol and diesel generators

Generators are critical safeguards during power outages or on remote job sites without grid connection. If an aggregate fails to start or outputs erratic voltage, equipment damage and costly work stoppages follow.

AVEMAK delivers qualified mechanical overhauls, electrical frequency and voltage testing, and regular maintenance for portable and stationary generators. We inspect AVR regulators, service fuel systems, and test machines under simulated electrical load.

Fehlerdiagnose & Instandsetzung

Common Failure Symptoms & Overhaul

Typical mechanical, electrical, and hydraulic issues diagnosed and resolved at our Berlin workshop

Fallbeispiel 1
Failure Symptom:

Engine starts and runs smoothly, but no power output at sockets

Probable Cause:

Loss of residual field magnetism, worn carbon brushes, or failed AVR module.

Professional Resolution:

Rotor/stator resistance testing, excitation circuit re-flashing, and brush/AVR replacement.

Fallbeispiel 2
Failure Symptom:

Output voltage collapses as soon as an electrical load is switched on

Probable Cause:

Governor linkage out of adjustment, fuel restriction, or engine power shortfall.

Professional Resolution:

Speed governor recalibration, fuel filter renewal, and carburetor/injector cleaning.

Fallbeispiel 3
Failure Symptom:

Generator refuses to start after months in standby storage

Probable Cause:

Gummed jets from aged fuel or water condensation in the fuel tank.

Professional Resolution:

Tank drain, ultrasonic carburetor cleaning, spark plug renewal, and fresh fuel charge.

Fallbeispiel 4
Failure Symptom:

Generator output fluctuates wildly between 180V and 250V

Probable Cause:

Failing automatic voltage regulator (AVR) or engine hunting caused by a blocked idle jet.

Professional Resolution:

Multimeter diagnostics of the AVR module, installation of OEM replacement, and fine calibration of governor linkage.

Frequently Asked Questions (FAQ)

Key answers regarding diagnostics, replacement parts, and logistics

Why does stale fuel cause generator failures?

Modern fuels degrade within months, absorbing humidity and gumming carburetor jets. For standby generators, we recommend fuel stabilizers or alkylate fuels.

Can sensitive electronics be run on site generators?

Only if the unit features inverter technology or high-precision AVR regulation. Standard generators produce voltage spikes. We can verify your unit's stability.

How often should standby generators be serviced?

At least once annually with a full load test and oil change to ensure immediate start-up during emergencies.

Can you test generators under full operational electrical load?

Yes, our workshop is equipped with electronic variable resistive load banks to verify frequency stability (50 Hz), voltage regulation, and thermal dissipation under 100% capacity.

What should I do if a generator will not start after long storage?

Stale fuel frequently clogs internal carburetor jets. We conduct ultrasonic carburetor cleaning, replace fuel lines, and supply high-performance fuel stabilizers.
