## At a glance

- The listing claims open-circuit and short-circuit locating, along with a separate continuity mode.
- Three sensitivity modes are described for open-circuit tracing.
- Transmitter and receiver signals use lights and beeps, according to the listing.
- The listed contents are transmitter, receiver, test leads, user manual, and battery.

## Pros

- Combines wire tracing and continuity checks in one listed tool.
- Light and sound indicators offer two ways to follow the transmitter and receiver signals.
- Three sensitivity modes are stated for locating open-circuit breakpoints.

## Cons

- Tracing is specified to work only on powered wires, which limits use on unpowered circuits.

## Before you buy

- The listing says tracing works only on powered wires and may require the vehicle ignition to be on. It describes different signal patterns for open circuits, shorts, and continuity checks, so use the stated mode-specific indicators rather than treating one signal as a universal result.

## In the box

- Wire tracer transmitter (Included)
- Tracer receiver (Included)
- Test leads (Included)
- User manual (Included)
- Battery (Included)

## A good fit for

- Automotive and RV wiring troubleshooting where the circuit can be powered during tracing.
- Users who want a single listed tool for open and short locating plus continuity checks.

## Less suited to

- Tracing unpowered wiring, which the listing says will not produce a receiver beep.
- Buyers seeking a general-purpose tester with capabilities beyond those specifically described for DC wiring.

## Customer feedback

The supplied customer feedback appears mismatched to this wire tracer: it refers to Wi-Fi, Alexa, stud finding, and independently controlled outlets, none of which are supported features here. The aggregate ratings lean positive overall but include a meaningful spread of lower-star ratings. Those figures do not establish how this tracer performs, so they offer limited guidance for buyers assessing powered-wire tracing and continuity use.

## Frequently asked questions

### Does the YDS-681 trace unpowered wires?
The listing says it works only on powered wires and that an unpowered wire will not produce a receiver beep. Some vehicle circuits may need the ignition switched on.
### Can it check continuity?
Yes. The listing describes a dedicated continuity mode using red and black test clips connected to both ends of the wire.
### How does it indicate an open circuit or short?
The listing describes light and beep patterns that differ by mode and location. It also claims three sensitivity modes for open-circuit tracing.
