Anyone come across this one? i was changing a 24v relay on a truck, the centre terminal was marked 87b, unlike a 'standard relay' the centre terminal is NOT normally closed!

If the relay is OEM, you will notice alot of differencs in the pin out configuration. Even a relay that appears to be a five pin relay looking like a standard Bosch, P&B, Midtex, etc.
Are in fact not, configured in the same manner. Why?? I have no clue why they do this . . . That is why the standard was created in the first place, but many manufactures still refuse to follow it.

Sounds like you have a SPST relay. BOTH terminals are tied together and are configiured in the NO mode. They're available in 12VDC as well. They're quite useful when you want to power two circuits off teh same switch w/o having to splice wires to the output. One device is connected to eash output. To my knowledge, the two terminals are divorceds when the relay is relaxed. ------------- Skip

Hi folks, if you look at the base of an automotive relay and the centre pin and output pin both have the number 87 next to them then these two pins are permanently joined together and this type of relay is usually call a headlight relay.
If the centre pin is numbered 87a then the pin is normally closed when the relay is not energised. This type of relay is a change over relay and is also commonly known in the automotive industry as an air conditioner relay.
The relay you have, and I’m not 100% sure on this one, but I think this is similar to a headlight relay but with this one, the two out put pins, 87 and 87b, are not connected together when the relay is not energised.
Cheers
