A simple ohmmeter is all that is needed to troubleshoot a potential relay. After taking all of the connecting wires off of the potential relay, measure the resistance across the 1 and 2 terminals. The ...

Not long after I began contributing to Hagerty eight years ago, I wrote a detailed four-part piece on electrical relays and how they work in cars. You can still find the articles here (Part I: Why We ...

The 385 series is a family of mechanically latched, electrically reset relays targeting applications where the relay contacts must re-main in the last set position with the power off. Terminals ...

Terminals 4 and 6 are used for capacitors and/or condenser fan connections and have no electrical significance to the starting relay itself, as shown in Figure 1. In fact, terminals 4 and 6 are ...

Fig. 1:Regularly check the date and time on your EAS equipment. With many people installing new CAP-compliant gear, Jim Davis of Radio One Raleigh writes with an idea of what to do with your old box.

When it comes to electronics, it seems like a relay is such a simple device – yet, it is able to interface some pretty elaborate high-end systems with a fire alarm system. Working with relays is an ...
