Complete On-board Generator Services for Mobile Applications

Whether you're dealing with a generator emergency breakdown or scheduling routine maintenance, we provide comprehensive on-board generator services:

Emergency Repair & Diagnostics

Generator failures don't wait for convenient times. When your food truck won't start on event day or a tour bus loses power mid-trip, you need immediate help. Our technicians use advanced diagnostic equipment to quickly identify problems and implement repairs that get you operational again.

Common emergency repairs we handle include:

  • Won't start or no power output (battery, starter, fuel delivery issues)
  • Runs but can't carry electrical load (voltage regulation, capacity problems)
  • Overheating and automatic shutdown during operation
  • Fuel system problems affecting performance and reliability
  • Transfer switch failures preventing automatic operation
  • Control panel and electrical system malfunctions

Routine Maintenance & Tune-Ups

Preventive maintenance keeps generators running reliably and prevents expensive emergency repairs. Moreover, regular service extends equipment life and improves fuel efficiency. Our comprehensive maintenance service includes:

  • Complete oil and filter changes using manufacturer-specified fluids
  • Spark plug inspection and replacement on gasoline units
  • Air filter cleaning or replacement for optimal performance
  • Fuel system cleaning and carburetor service when needed
  • Battery load testing and connection cleaning
  • Cooling system inspection and coolant testing
  • Exhaust system inspection for leaks and proper function
  • Electrical system testing including voltage and frequency
  • Control panel function verification and alarm testing
  • Complete operational testing under load conditions

Load Testing & Performance Verification

Running a generator without load doesn't reveal potential problems. Therefore, we perform comprehensive load testing that simulates actual operating conditions. This process identifies voltage regulation issues, overheating problems, and capacity concerns before they cause failures during critical business operations.

Fuel System Service

Fuel quality and delivery problems cause many generator failures. We service gasoline, diesel, and propane fuel systems, addressing issues like contaminated fuel, clogged filters, carburetor buildup, and fuel pump failures. Additionally, we'll help you implement proper fuel management practices that prevent future problems.

Tour Bus & Motor Coach Generator Service

Tour bus operators understand that passenger comfort directly affects their business reputation. Generators power HVAC systems keeping passengers cool in summer and warm in winter. Furthermore, they run entertainment systems, charging ports, and restroom facilities that modern travelers expect.

A generator failure mid-route creates uncomfortable passengers and schedule disruptions. That's why charter companies and tour operators traveling through Michigan count on us for reliable generator service.

Tour Bus Generator Services Include

  • High-Capacity System Expertise: Tour bus generators are larger and more complex than typical RV units. We have the experience and equipment necessary to service these substantial systems properly.
  • Quick Turnaround Service: We understand buses operate on schedules. Call ahead when you'll be in Wixom or Zeeland, and we'll complete service efficiently to keep your operations on track.
  • Load Testing Under Full Load: Running HVAC, lights, entertainment systems, and charging ports simultaneously creates significant electrical demand. Therefore, we test generators under conditions matching actual passenger load requirements.
  • Cooling System Maintenance: Large generators produce substantial heat. We thoroughly service cooling systems to prevent overheating issues that could strand your bus and passengers.

Food Truck Generator Service: Protecting Your Mobile Restaurant Investment

Food truck owners face unique challenges. Your generator must power commercial-grade cooking equipment, refrigeration, and lighting for extended periods. Meanwhile, you're operating in varying weather conditions, different locations, and often running at or near maximum capacity.

Generator failure means immediate revenue loss. Spoiled inventory, cancelled events, and disappointed customers all impact your bottom line. That's why successful food truck operators throughout Metro Detroit, Ann Arbor, Lansing, Grand Rapids, and other Michigan markets prioritize generator maintenance.

Common Food Truck Generator Issues We Repair

  • Overloading Problems: Running too many appliances simultaneously strains generators. We'll assess your electrical load and verify your generator can handle peak demand. Additionally, we can recommend capacity upgrades if needed.
  • Voltage Fluctuations: Inconsistent power damages sensitive equipment and creates food safety concerns. We diagnose and repair voltage regulation issues that affect your commercial appliances.
  • Extended Runtime Issues: Long operating days stress generators differently than short-term use. Therefore, we focus on cooling system health, lubrication quality, and component wear patterns specific to food truck applications.
  • Start Failures: When you arrive at an event and your generator won't start, you're facing disaster. We service starting systems, batteries, and fuel delivery components that ensure reliable starts every time.

Pre-Season Food Truck Generator Maintenance

Before festival season and busy summer months, bring your food truck in for comprehensive generator service. We'll inspect all critical systems, perform necessary maintenance, and load test your generator to verify it's ready for demanding operating schedules. Moreover, catching small issues during off-season prevents expensive breakdowns during your busiest revenue periods.

RV Generator Repair for Rental Companies & Private Owners

RV generators serve both commercial rental operations and private owners throughout Michigan. Whether you're operating a rental business or own a personal motorhome, generator problems disrupt trips and create frustrating situations.

Rental businesses can't afford units sitting in the shop during peak season. Every day a unit is down for generator repairs represents lost rental income. Additionally, generator problems discovered by renters result in negative reviews that damage your business reputation.

We provide rental companies with:

  • Generator repairs that minimize lost rental days
  • Pre-rental generator inspection services to catch problems before customers take delivery
  • Post-rental generator checks to identify issues caused during rentals
  • Generator Preventive maintenance programs scheduled during your slower periods
  • Detailed service documentation for your generator maintenance records

Safety Tips for On-board Generators

  1. Be aware of the exhaust! Generators produce carbon monoxide at a high level, just like a car does. You don’t want the exhaust blowing into air vents or into crowded spaces.
  2. Make sure the generator is properly grounded. Many electrical issues can be traced back to a faulty ground.
  3. There are a lot of hot parts on generators when they’ve been running. Make sure to stay clear of mufflers and engine parts.
  4. Don’t refuel when the the generator is on or still hot.
  5. Have a fire extinguisher ready to go. That means make sure its up to current standards, fully charged and easy, quick access in case of emergency.
  6. Know the limits of your generator. What kW is it rated for? You don’t want to put too many things on the generator and have it strain and break down.
  7. Make sure to keep the air intake and radiator is clean and no debris is blocking. Do this prior to turning on the generator.
  8. Make sure your battery is fully charged
  9. Watch for fluid leaks, such as coolant and oil. Check fluids at least once a week.
  10. Service the generator! If your generator is gasoline or propane, then we recommend it to be serviced after about 100 hours. A diesel generator should be serviced at about 250 hours.

If you need help with any of the above items in the list for your on-board generator, call at 1-800-485-8068 and schedule and appointment. Make sure your on-board generator is ready when you are.

Common Generator Problems We Repair on Commercial Vehicles

Won't Start / No Power Output
Battery failures, starter issues, fuel delivery problems, and ignition system failures prevent generators from starting. We diagnose and repair these start system issues quickly to minimize your downtime.
Runs But Won't Carry Load
When generators start but can't power your equipment, voltage regulation problems or capacity issues are often responsible. Furthermore, these situations require specialized diagnostic equipment to identify the root cause.
Overheating & Shutdown
Cooling system failures, blocked airflow, low coolant, and thermostat problems cause generators to overheat during operation. Therefore, we inspect and repair cooling systems to prevent heat-related failures.
Poor Fuel Economy / Performance
Carburetor issues, fuel system contamination, air filter restriction, and improper adjustments reduce efficiency. Consequently, we restore optimal performance and fuel consumption through proper service and adjustment.
Excessive Noise / Vibration
Mounting problems, exhaust system issues, and engine wear cause abnormal noise and vibration. Additionally, these symptoms often indicate developing problems that require attention before major failures occur.
Intermittent Operation / Surging
Electrical control issues, governor problems, and fuel delivery inconsistencies cause unreliable operation. Our diagnostic process identifies these intermittent problems that may not be apparent during basic testing.
Control Panel / Switch Failures
Electronic controls and transfer switches require specialized knowledge to diagnose and repair properly. We service these components on all major generator brands used in commercial vehicles.

Recommended On-Board Generator Maintenance Intervals for Commercial Applications

Commercial generators accumulate operating hours faster than recreational use. Follow these general guidelines, though your specific operating conditions may require more frequent service:

  • Gasoline/Propane Generators: Service after 100-150 operating hours or annually, whichever comes first. Food trucks and vehicles with heavy daily use may require quarterly service.
  • Diesel Generators: Service after 250-300 operating hours or annually. Tour buses and other high-use applications should track hours carefully to avoid exceeding service intervals.
  • High-Load Applications: Generators consistently running near capacity (food trucks, mobile medical) benefit from more frequent oil analysis and cooling system maintenance.
  • Seasonal Operations: Pre-season and post-season service protects equipment during storage and ensures reliability when vehicles return to service.

Call 1-800-485-8068 to discuss a maintenance schedule tailored to your specific commercial operation and operating patterns.
