​At BEC Technical, we specialize in advanced electrical diagnostics and electrical troubleshooting for electromechanical packaging equipment across Northern and Southern California. Our skilled technicians are experts at uncovering the root cause of electrical failures in complex systems — saving you time, money, and costly downtime.

 

Whether you’re dealing with intermittent faults, failed starts, or mysterious machine behavior, our in-depth understanding of electronic and mechanical systems allows us to pinpoint the issue quickly and accurately. From electrical system repair to component-level electronic repair, we’re your trusted partner in keeping your packaging equipment running at peak performance.

Troubleshoot and Diagnose Hard-to-Find Electrical Problem

When packaging equipment breaks down due to electrical issues, the problem is often hidden deep within the system. Our team is trained to handle difficult cases — the ones that leave other technicians scratching their heads. We go beyond the surface symptoms to uncover and resolve problems such as:
 

  • Open or shorted circuits

  • Malfunctioning sensors and switches

  • Relay logic failures

  • Faulty PLC inputs and outputs

  • Inconsistent signals from VFDs and DC drives

  • Power quality issues

  • Poor grounding or shielding causing electrical noise
     

These are not your average repairs. They require a methodical, systems-based approach to electrical troubleshooting that only comes from years of hands-on experience with electromechanical machinery.

Our Electrical Diagnostic Process

BEC Technical follows a structured, step-by-step approach to every electrical diagnostic project. This ensures no detail is missed and every issue is verified before we consider the job complete:
 

  1. Initial Assessment: We begin by collecting information on the failure. What symptoms are present? When did they start? Was there a recent change in operation, power supply, or environment?
     

  2. Visual and Mechanical Inspection: Next, we perform a thorough inspection of the machine’s wiring, panels, connectors, and control systems. We’re looking for obvious signs like burnt wires, loose terminals, or damaged components.
     

  3. Signal Tracing & Circuit Analysis: Using advanced diagnostic tools like multimeters, oscilloscopes, and current probes, we trace electrical signals through the system to isolate the problem. This includes analyzing wiring diagrams, relay logic, and sensor feedback.
     

  4. PLC, VFD & Drive Testing: We test and validate programmable logic controllers (PLCs), variable frequency drives (VFDs), and DC motor drives. This often includes uploading programs, checking I/O response, and verifying drive parameters.
     

  5. Component-Level Testing: When necessary, we dig deeper with component-level electronic repair, testing resistors, capacitors, transistors, and ICs within boards or control modules.
     

  6. System Restoration: Once the root cause is confirmed, we proceed with electrical repair or replacement of defective components, and restore the system to full operational status.
     

  7. Component-Level Testing: Before we sign off, we test the machine under load and confirm that the original issue is resolved, and that no secondary problems exist.

Why BEC Technical?

✅ Specialized Expertise
We don’t just replace parts — we understand how machines work from the inside out. Our knowledge of how electrical actions trigger mechanical reactions (and vice versa) sets us apart in the world of technical service.

✅ Fast, Accurate Diagnostics
Our priority is getting your machine running again — fast. Our diagnostic process is designed to minimize guesswork and maximize uptime by identifying the true cause of failure on the first visit.

✅ Field-Ready Professionals
We service all of California — both Northern and Southern regions — with a mobile team equipped with diagnostic tools, replacement parts, and the skills to tackle even the most elusive electrical issues.

✅ Preventative Recommendations
After each service, we offer insight into how future failures can be avoided. From upgrading outdated wiring to optimizing PLC logic, we help extend the life of your equipment and reduce unscheduled downtime.

Electrical System Repair That Goes Beyond the Obvious

Too many repair jobs are rushed — with parts swapped out based on a hunch rather than a proper diagnosis. At BEC Technical, we dig deeper. Whether it's electrical system repair, circuit rework, or full electronic repair of boards and drives, we believe in fixing what’s actually broken — not just what’s easy to replace.
 

We also support:
 

  • Reverse engineering of legacy systems
     

  • Sourcing and installing hard-to-find components
     

  • Updating old wiring schemes with modern safety standards
     

  • Integrating new electronics into older equipment
