How the DIRECT™ System Works

Purkeys’ DIRECT™ is a single-source liftgate charging system. It boosts voltage through a DC to DC converter to fully charge liftgate batteries more efficiently and to overcome the voltage drop from the tractor to the liftgate batteries. The DIRECT has easy-to-read LED indicators. If the liftgate battery indicator shows a green light, the liftgate batteries...

The Importance of Checking Circuit Integrity

The continuity function on a multimeter is a helpful measurement, but it does have its limitations. Once continuity has been checked, verifying the condition of the wiring of the entire circuit is essential. A circuit with a good continuity reading may still have issues like voltage drop stemming from simple problems such as a frayed...

Using your Multimeter’s Continuity Function

One of the many functions of the Multimeter included in Purkeys’ Electrical Tool Kit is the continuity test mode. Using this setting, technicians are able to test the circuit for a stable connection and eliminate continuity as a possible problem with the system. While continuity test mode is a helpful function, it does have its...

Test Entire Vehicle Electrical Systems

If fleets want to reduce, or even eliminate, electrical issues, they need to equip their technicians with high-quality electrical testing equipment. That is why Purkeys provides the Benchtop Electrical Analyzer. When portability is not a concern, a roll-around tester, like the Benchtop Electrical Analyzer, is what every fleet needs. It is an automated tester that...

Purkeys’ Clip-On Ammeter Measures Low Current

Purkeys’ Milliamp Clip-On Ammeter accurately measures low current and detects parasitic loads in electrical systems without disconnecting the circuit. Parasitic draw on batteries can deplete a charged battery over a period of time, even when the vehicle is not in use. Batteries that remain discharged for long periods of time can receive internal damage and...

Electrical Experts, Yes. Hollywood Actors, No.

The Purkeys team has spent another full year creating videos full of electrical advice and knowledge. While we are electrical experts, we are far from actors. You would think after 3 years of creating videos every week we would have this acting thing down but alas, we won’t quit our day jobs. Here are some...

TAPS™ Keeps Pallet Jacks Charged and Ready

TAPS™, short for Trailer Auxiliary Power System, is a simple tool to ensure electric pallet jacks perform reliably and efficiently. Drivers spend a lot of time on the road. Depleted electrical equipment batteries can slow fleets down with unnecessary road calls, but Purkeys’ TAPS can charge electric pallet jack batteries between stops. TAPS uses an...

PAC Helps Batteries Charge Through the Cold

Purkeys’ Pack Accelerated Charger (PAC™) can help fleets keep batteries at a good state of charge during cold winter months. A fully-charged battery will perform well in cold weather. Fleets will start to see problems when their batteries become severely discharged. It is well known that cold weather makes it harder to crank a motor....

Purkeys’ 6-Station Battery Charger

Fleets have trouble keeping batteries fully charged in cold weather. Batteries produce energy through a chemical reaction. As temperatures drop, so does the rate of reaction. This contributes to batteries producing less energy. If batteries don’t produce enough energy to meet the cranking requirements, fleets will have trouble starting their vehicles. This leaves fleets with...

Guide Technicians Through Electrical Tests

One of the most important parts of maintaining vehicle electrical systems is having good electrical testing equipment. Purkeys’ Handheld Electrical Analyzer automates the testing process, allowing technicians to quickly and easily test electrical systems. This handheld tester has a menu-driven system that guides technicians through tests for heavy-duty vehicle cranking, charging, and battery systems. It...
