About Rignostics

When the problem
isn't obvious,
experience matters.

Modern RVs have become increasingly complex. Generator systems, inverters, converters, transfer switches, battery systems, multiplex wiring, and electrical controls all work together — and when something goes wrong, finding the cause can be more difficult than fixing the symptom.

With more than 30 years of hands-on RV experience, we specialize in diagnosing the problems that aren't always easy to find.

We don't guess. We diagnose.
What We Do

PRIMARY SERVICES

Specialist service for RV generator systems, electrical diagnostics, and integrated power systems.

Why Rignostics

THE DIFFERENCE

Real RV Experience

More than three decades of hands-on experience working with RV systems, equipment, and repairs — not a certification, a career.

Diagnostic-First Approach

We focus on identifying the actual cause of a problem rather than simply replacing parts until something works. Accurate diagnosis saves time and money.

Specialized Mobile Service

Professional service brought directly to your RV, without the inconvenience of transporting a large coach or trailer to a shop.

Complex Systems Expertise

Generator, electrical, charging, inverter, converter, battery, and integrated power-system problems are where our expertise is most valuable.

30+ Years

EXPERIENCE YOU CAN'T GET FROM A CERTIFICATION

We've been working with RVs for more than 30 years. Over that time, we've worked on thousands of RVs and encountered virtually every type of mechanical, electrical, generator, and systems problem imaginable.

That experience matters most when the problem isn't straightforward. When other people have replaced parts and still can't find the problem — that's where our experience becomes valuable.

  • Wiring problems
  • Rodent-damaged wiring
  • Parasitic draws
  • Charging problems
  • DC electrical issues
  • AC electrical issues
  • Difficult-to-trace electrical failures

About

EXPERIENCE MATTERS

With more than 30 years of experience in the RV industry, we bring decades of hands-on knowledge directly to the customer.

Our experience comes from working with thousands of RVs and personally dealing with the mechanical, electrical, generator, and systems problems that RV owners encounter.

We've worked through decades of changes in RV technology and have developed a particular strength in diagnosing complex problems that aren't always immediately obvious.

Today, that experience is focused on providing specialized mobile RV diagnostics, generator service, electrical troubleshooting, and power-system expertise.
