Universal Zebra UZ-1 bestseller

The Most Versatile Weapon in Your Arsenal Against ECM Motor Problems ...

Universal Zebra Photo

The Universal Zebra is able to test run a motor in one or more (up to six) speeds. It has seven LEDs and three 3-way switches. It arrives with one popular Adapter, which fits the very common GE/Regal-Beloit Series 2.0 and 2.3 motors. It is housed in a rugged, latchable case that protects the tool, the harness, and the power input clips. Inside the lid is a place for each Adapter's corresponding magnetic overlay card, which describes the functions of each switch and LED with respect to that specific motor series.

The System consists of 4 categories of tools, many of which are optional, so your System is customized to you, and to the way you work.

• • • The Basic Tool is model UZ-1 (we affectionately call it the UZI.) It is able to test run a motor in one or more (up to six) speeds. It has seven LEDs and three 3-way switches. Housed in a rugged case that latches, it is shipped with one popular adapter, which fits the very common GE/Regal-Beloit Series 2.0 and 2.3 motors.

• • • Adapters couple the Universal Zebra to the motor. Six different Adapters were available when the tool was released, with many more to come. In fact, we’re committed to making low-cost Adapters available for virtually every new ECM motor that is introduced into the HVAC-R Industry. The PWM Signal Generator Adapter is available for testing motors that utilize PWM signal inputs.

• • • Motor Power Plugs with Harnesses are necessary when you want to test a motor out of its air handler/furnace environment. Most ECM motors have special power input plugs, so bench testing can be challenging without access to these plugs. A wide variety is available, with more to come.

• • • Accessories round out the System: • A 24" extension for the tool’s main harness is available (it can also be used to replace the original harness if the fan wheel gets too close!) • A rugged accessory case is available to protect your adapter and harness collection from getting damaged or lost. • Other items will be added to this category as you ask for them.

Side Winder Photo

NEW! Side Winder SW-5
Diagnosing which section of an ECM motor has a
problem has never been easier. Why might the SideWinder help make your ECM problem diagnosis more accurate? So, you have traced the problem down to the ECM motor - but which section of the motor is the cause of the problem? If you send back the whole motor (the module and the winding section), you may be subject to chargebacks under warranty, or you may unnecessarily spend hundreds of the customerís dollars for out-of-warranty parts.

Many unit manufacturers are starting to deny warranty claims for mis-diag-nosed ECM motor problems. After years of giving Technicians grace after sending back the complete motor, the unit makers realize that the tools now exist for a Tech to properly determine when only a module - instead of the complete motor - required replacement.

About 30 seconds is all that is needed to administer the SideWinderís two main tests - and it may save you money, hours of work, and possibly the embarrassment when an ECM motor claim is later denied.

Variable Speed Zebra Photo

Variable Speed Zebra VZ-7
Variable Speed Blower motors are complex, expensive, and with 9 million installed in U.S. systems, here-to-stay. GE reports that 41% of these motors that are returned to them as defective have "no problems found"! That says that the current generation of tools to diagnose problems with the motors is missing the mark. The VZ-7 is a simple-to-operate, intelligent tool that clearly diagnoses these systems so you won't replace the wrong part. Just one Variable Speed Motor costs twice what this tool does; don't make a costly mistake. Displays CFM, RPM, & more. Training and Educational DVD included, Click here to watch it on YouTube, or click here to download. Click to find out more.

ZebraStat ZS-2
is a compact electronic tool that helps to diagnose problems in the low-voltage control circuits of HVAC and refrigeration units. It also acts as a convenient remote control for technicians working in attics, on rooftops, or in basements, where easy access to temperature and system controls is inconvenient. Other useful features are built in to the ZebraStat - click here for more.

We all know a tech who's done it: It's hot, he's tired, and he makes a simple mistake when he hooks up his cordset to get power from the condensing unit to run his vacuum pump. He throws the switch on the pump and - POOF - the smoke escapes from the vacuum pump, rendering it useless until expensive repairs can be made. Zebra'Dapters provide a visual indication of voltage levels before damage can occur. And, if the indicator lamp is ignored, the fuse provides a last line of defense to protect your valuable tools from simple mistakes.

are alligator clip jumper wires designed for the HVAC/R Technician. Unlike competitive products, the alligator clips don't pull off the wires because they're soldered, not just crimped. They come in as many as eight colors for the more complicated jobs. Each set comes with a hook-and-loop strap that keeps your Zebra-Gators organized, either in the tool box or hanging up in your vehicle. Zebra Gators currently come in three different gauges 22 Gauge (ZG002),18 Gauge (ZG003), and 14 Gauge (ZG004) Click to find out more. (Click the photo to enlarge)

Photo of some Circuit Protection Products

Circuit Protection
products for the HVAC/R Professional are often-used parts, packaged in convenient multi-packs of heavy-gauge resealable vinyl bags. Common fuses are in 25-packs. The new Z•Breakers are snap-in protection for all systems. Much more convenient than replacing a fuse, they can allow a customer to just push-to-reset a breaker, often allowing a middle-of-the-night service call to be postponed until the next day. With a Trade Price of about $7, many contractors are installing them in every new system. Click to find out more.
