funny funny relay

mmmkay, well...I don't know how many kinds of automotive relays there are out there but I guess I must've bought the wrong ones. And considering I bought them because they look like regular relays I've come to know then I guess I was just asking for it :)

Anyway, on these- pin 87a is just labeled 87, and 87 is well..87. 

At rest pin 30 has no continuity with either of the 87's, but there is continuity between both 87's.

When energized all the pins 30,87,87 have continuity with each other. Other than that, what I thought was a dead relay looks more like a different type of relay. (in fact on second look of the schematic on the casing it's actually drawn out in front of me) (does anyone know what name it goes by?)

Originally I was trying to use them on my 5 wire door locks but each time I kept blowing a fuse on the 12v wire that powered all the necessary pins on the 2 relays.. So I separated the 12v wire and isolated the fuse shorting to pin 87. I really don't why but I guess it has something to with all the pins being fed the 12volts when energized. Besides that the door locks wouldn't even work at rest because pin 87 (12v) had continuity with the middle pin (87a on a regular relay).

My point is that I made an error in buying my relays and now have 2 that I've no idea what to do with. If anyone out there can think of an application that can benefit from this kind of relay setup I'd love to hear from you. (dome light, rear defroster, headlamps etc..)

Thank you to all who tried to help me recently- no doubt will I need it again someday.

well, now I know..thanks guys- even though I had to find out the hard way :)

Anyways, earlier today I tested a SPDT relay (used for my SK) on the lock mechanism for my locks (the unlock wires were left alone) basically setup according to the 5 wire diagram but for just for lock cuz I only had one relay. Anyway, the power to the coil is directly from the battery & fused at 30a. Power to the pole on the relay is powered by an interior 12v wire and fused at 25a. The problem is that when I unlock the doors via remote the locks don't go down enough to lock the doors- they go down about 3/4 of what it should. I tried changing the lock pulse on the alarm to 1/10th sec. from the default 7/10th sec. but it only seemed to go down even less. There is a 4 sec. pulse option but I was hesitant to try it. Should I? Or is there something else going on here that needs tweaking?

interesting!

I'll give it a try and post the results..

thanks
