Faultsmith

Read. Diagnose. Solve.

A service manual reader built for generator technicians. Look up a fault code and land on the test that fixes it — not on the page it happens to sit on. Works with no signal, on the manuals you already have.

Oil Pressure Switch Test

opens at the heading — not the top of the page

The procedure itself, scrolled to where it actually begins.

The problem

A code on the display.
Three hundred pages in the way.

The manual has the answer. It also has a table that repeats itself three times, a cross-reference that gives a printed page number the PDF doesn't use, and a procedure that starts two-thirds of the way down a page — under the tail of the previous one. Scroll to the top of that page and you are reading the wrong test.

Faultsmith reads the manual once, up front, and remembers where everything actually is.

What it does

Built for the job, not for a demo

Lookup

Fault codes, by number or by name

Type what the controller shows. Numbered e-codes, or the plain-language faults a transfer switch displays instead of numbers.

Anchoring

Lands on the test

Cross-references resolve to the procedure's heading, wherever it starts on the page. No landing mid-way through the previous test.

Contents

A contents page that isn't there

Sections, fault tables and multi-sheet drawings are found automatically — including which sheet is 4 of 6.

Glossary

Wire and component lookup

What SM, CRKS or wire 23 means, and the page it was read from — in the manual it came from, not a different one.

Markup

Draw straight on the page

Trace a circuit through a schematic without leaving the manual. Your marks stay on the page you made them on.

Notes

Readings, stamped to the page

A pad that pops out mid-test for voltages and resistances, with photos of a nameplate or a burnt connector kept alongside.

Offline by design

No signal. No account. No cloud.

The job happens in basements, crawl spaces and the back of a truck. An app that needs a connection is an app that fails exactly when you need it.

Everything on the device

Manuals, notes, markup and photos are stored locally. Nothing is uploaded, because there is nowhere to upload it to.

No sign-in

There are no accounts and no user data, so there is nothing to lose, leak or lock you out of.

Your manuals stay yours

Faultsmith ships no manufacturer's manuals. You import the PDFs you already have, and they never leave your device.

Status

In beta

Beta — iPad & iPhone

Faultsmith is in private testing on iPad and iPhone. It is not yet on the App Store.

It is being tested against real service manuals — several hundred pages each, several different table formats — and refined against what actually breaks in the field. If you service generators and want to try it, get in touch.
