Tornado Strike Wiring, Sensor K66519020

The sensor wiring (part# K66519020) is the harness that carries the parking position sensor’s signal back to the motherboard on the Tornado Strike TV190-W10-U. It costs about a twentieth of what the sensor does, and it produces the same symptoms when it fails — which makes it the first thing to check, not the last.

Compatible Models for the Wiring, Sensor

• Tornado Strike Cordless Upright Vacuum — Model TV190-W10-U

This is a Strike-only component: Tacony’s parts records list the Tornado Strike TV190-W10-U as the single machine that takes part# K66519020, so there is no cross-model substitution to worry about when you order it.

What the Wiring, Sensor does

Unlike the motor harnesses, this one carries a signal rather than working current. That makes it more sensitive to a poor connection, not less: a few ohms of corrosion in a power cable is nothing, but in a signal line it can be enough to make the board read the sensor wrongly. The loom runs between the base of the machine and the electronics, so it flexes as the machine is reclined and raised.

Signs the Wiring, Sensor needs replacing

A brush that will not run when reclined, a brush that runs when it should not, or behaviour that changes as the machine is moved all point here as readily as they point at the sensor. Look at the whole run: chafe marks where the loom passes the pivot, a connector that has worked loose, green or dark pins, or a conductor that has fatigued from flexing. Wiggle-testing the loom with the machine powered is a legitimate diagnostic here.

Fitting the Wiring, Sensor

Battery out first. Photograph the routing, especially where the loom crosses the pivot, then release both connectors by their latches. Fit the replacement along the same path with the same slack — a harness routed too tight across a pivot will fatigue in months — and make sure it is retained in its clips. Test by reclining and raising the machine several times and confirming the brush responds correctly each time.

Frequently Asked Questions

Should I replace this before buying a new sensor?

Yes, in most cases. The cable and the sensor produce the same symptoms, and this part costs a small fraction of the sensor. Check the cable and its connectors properly before spending on the sensor.

How do I test the cable?

With the machine powered and the loom accessible, gently flex it along its run, particularly near the pivot, and watch whether the brush behaviour changes. Intermittent behaviour that follows the flexing is a failing conductor or connector.

Does it come with connectors fitted?

Yes. It is supplied made up with the correct connectors at both ends, so there is no splicing to do.
