Cable Assembly
A wire harness tester is not just a bench tool. It is the control point that decides whether your receiving team installs a clean lot or spends days chasing swapped pins, missed seals, and undocumented rework. We help OEM buyers define tester logic, mating fixtures, pass-fail limits, and release records before samples and production builds begin.
Application Context
A wire harness tester is the control point that decides whether your receiving team installs a clean lot or spends days chasing swapped pins, missed seals, and undocumented rework. Rather than treating test as a hidden line item after PO release, engineering reviews your drawing, net list, mating side, resistance window, and report expectation before quotation so the tester scope matches the real harness risk. The baseline is 100% continuity, polarity and miswire detection — opens, shorts and swapped circuits — with resistance windows, with circuit-resistance windows where the application requires it. Insulation resistance and hi-pot are not run in-house; where an EV, industrial, or medical installation requires them, we coordinate them through a qualified third party. Where a program needs full electrical verification and release documentation, this aligns directly with an ICT / electrical testing service built around the same net list and pass/fail logic.
A tester only reduces risk when the approved golden sample, fixture interface, and report format stay stable through pilot and recurring production. Multi-branch industrial and panel harnesses rely on tester-driven continuity to catch branch mix-ups before commissioning, while high-voltage cable assemblies need hipot and insulation-resistance testing, which we coordinate through a qualified third party for objective dielectric release evidence. Whichever level applies, the output is not just a pass light on the bench — it is a release package with lot or unit-level records, fixture ID and revision tracking, and documentation procurement, receiving and quality teams can actually use.
Service Scope
Built for buyers who need fixture-ready verification instead of vague final inspection promises.
We review your drawing, net list, mating side, resistance window, and report expectation before quotation so the tester scope matches the real harness risk instead of being treated as a hidden line item after PO release.
Some programs need continuity only. Others need selected circuit-resistance windows to protect an EV, industrial, or medical installation from hidden defects; insulation resistance and hi-pot are coordinated through a qualified third party. We align the tester burden to the application consequence.
A tester only reduces risk when the approved sample, fixture interface, and report format stay stable through pilot and recurring production. We carry that control into release documentation so procurement, receiving, and quality teams are working from the same definition.
Where It Matters
Machine builders and panel integrators use tester-driven verification to catch swapped pins, branch mix-ups, and polarity errors before commissioning windows are lost.
Battery, charging, and safety-related assemblies often add resistance windows, with dielectric checks coordinated through a qualified third party, so the approved program covers more than basic continuity.
When your customer expects reportable pass-fail data, revision-linked records, or a stable fixture definition, tester planning becomes part of the procurement requirement, not a factory afterthought.
Technical Capabilities
Verification matched to buyer risk — continuity, polarity and miswire detection as the baseline, with circuit-resistance windows by drawing or control plan; insulation resistance and hi-pot coordinated through a qualified third party.
Manufacturing Process
Quality & Testing
Every tester program can combine 100% continuity and miswire detection with optional circuit-resistance windows by requirement (insulation resistance and hi-pot coordinated through a qualified third party) — each result captured in a lot summary, unit record, or certificate of conformance, with fixture ID and revision tracking, so receiving and quality teams have objective release evidence before shipment.
Why WHP
Because undefined tester logic usually turns into installation delays, not savings.
We quote against actual fixture effort, acceptance limits, and report depth instead of hiding tester cost inside generic production overhead.
Ambiguous connector orientation, missing resistance windows, and incomplete test logic are flagged before first samples are built.
The objective is not just a passing prototype. It is a tester definition that can survive pilot builds, recurring releases, and receiving audits.
We align output with the documents procurement and quality teams actually use, including fixture references, revision control, and report format expectations.
These references help buyers compare workmanship expectations, electrical-safety context, and documented quality systems before approving a tester plan or supplier.

Representative project type (illustrative)
industrial-equipment
An industrial equipment manufacturer completed a year-long testing phase of custom wire harness samples and provided specific dimensional feedback.
The field testing revealed a specific mismatch: the conduit size on a primary harness model was 15mm, which did not meet the client's assembly requirements.
Our engineering team immediately reviewed the 15mm conduit specification feedback, collaborated with the client's engineers to define the correct dimensions, and prepared a revised quote for the updated samples and the 200-piece bulk order.
Turned a potential project rejection into a collaborative design refinement, advancing the project to the next sample iteration and securing an expanded scope of inquiry for new product lines.
