Tending Liftgate Batteries

By Tom Berg

Bruce Purkey knows where the electrons go. And, as president of Purkey’s Fleet Electric and his many activities in the Technology & Maintenance Council of the American Trucking Associations, he’s well aware that some of them flow to batteries that support the electric-over-hydraulic systems for liftgates on trucks and trailers. Usually there are two and as many as four Group 31 batteries, like the ones on a truck or tractor.

A Systems Approach to Start/Charge System Maintenance

All that empty space between the winding is unused space. Square-wire windings make total use of the space and produce higher output.

By Jim Park

We have to stop thinking of our start/charge systems as simply a handful of separate components, and start viewing them as a system. From alternators to batteries and starters, cables and regulators, and even add-on components like low-voltage cut-off switches and DC/AV inverters, each can impact the component next to it.
