The part was cheaper in the store than online

By 

from Montgomery Alabama

Verified Buyer

Comments about Optronics 12VDC 40A Relay:

It was lower priced in the Store and when I ordered it online, and received the 20% discount, it didn't amount to much. I could've saved more by using my military discount (10%) and paying the stores price.

    No 87a Normally Closed Contact

    By 

    from VA

    About Me Mechanic

    Comments about Optronics 12VDC 40A Relay:

    This is a simple SPST relay and does include terminal 87a which is a normally closed contact. This will not work for applications like trailer converter systems requiring a normally closed contact. Their are no specifications indicating this or any other information. It is rated at 40 Amps now.

          I needed a center tap for normally closed like often used in keyless entry/horn/light installation, I guess if you only need a simple relay it would be ok.

          • Q:

            Does the Optronics A-715A 40-amp relay include a diode across terminals 85 - 86?

              Happy to answer your question Rick! This relay does not feature a diode. This Relay is for driving and fog lights and they do not back feed.

          • Q:

            This is the closest I can find to the relay switch for my Aerostich Ear Canon air horn, but I know the circuit uses a 30 amp fuse (http://www.aerostich.com/plug-n-play-wiring-harness.html), this relay is rated 40 amp. Will it work for my application?

              I'm happy to help, Steve! This Optronics 12VDC 40A Relay (Part No. A-715) will allow the air horn to operate. I have also found Wolo Part No. 400-R is a 30A relay that may work for your application.

              This could possibly be the problem. However, without the presence of your vehicle we would not be able to properly diagnose it nor provide you with a 100% answer. We would suggest that you take your vehicle to a certified mechanic for further diagnosis.
