In the June 2011 issue of Phillips Industries Qwik Tech Tips newsletter, a simple diagram shows the seven-pin round (J560) terminal functions as viewed looking into an open socket.
The subject of this newsletter is troubleshooting a lights-out situation, and the diagram is used as a visual aid to clearly identify specific circuits to test to pinpoint the problem. Supplying the newsletter, along with a socket circuit checker tool, to truck drivers would help them resolve a lights-out problem before being cited during a roadside inspection.
Qwik Tech Tips offers easy solutions to electrical maintenance issues facing trucking fleets. Each issue of the newsletter can be found at www.phillipsqwiktechtips.com or can be delivered in PDF format each month via e-mail by requesting that option on the website.
