Can anybody point me to a source of information on specifications for relays.

Relays are easy enough to come by from scrap yards and I would like to know how or where I can find out the current rating and whether not they are suitable for continuous or intermittent operation.

Nissan relays usually are color coded.

I would like this info because I wish to make up a seperate relay and fuse panel in an RV to operate of an auxilliary battery circuit and also to supply power to a Caravan (known as Camper Trailer in U.S.)

Cheers,

Oftentimes you can search on the manufacturer's name on the relay.. if it has it on there. You could look at the fusing for the circuit the relay is powering to get an idea of current rating and what the circuit is for to determine continuous or intermittent.

While I understand why you want to use scrap yard parts, at least look into cost of new relays.. if nothing else, you know that they are brand new vs. of unknown condition.

I also have an RV; if you have any other questions about anything, just ask.

Thanks Jim,

Most relays are made by "Nippondenso" but carry the vehicle part No, eg Nissan or Toyota etc and a search doesnt reveal anything.

Relays here are about $15 to $20 each and because the engine bay "Boxes" are only junk, it is easy to get them free. This also means getting relay sockets, fuse connectors etc which normally are hard to source.

Having worked in electronics for years, experience shows that generally relays don't create too many problems with age unless they are operating at their limits and burning contacts. My major concern is regarding the relay specs on Intermittent use against constant use such as Horn relay versus Fuel pump or driving light relay.
