Mods, if this is in the wrong area, please move it. The posts I saw in Off-Topic, were a little more off-topic than this. So it seemed best placed here.

I went to the local Pick-N-Pull today, looking for a gas tank. I didn't get the tank, but I did come back with 6 relays out of an Isuzu Rodeo. They are the Bosch style. The pinouts look like this:


There are 3 different numbers. The markings are as follows:

RELAY 1-
8970609260
12V 51019
JIDECO

RELAY 2-
8970609260
12V 51020
JIDECO

RELAY 3-
8970609260
12V 51023
JIDECO

I'm assuming that, since there are 3 different part numbers, that they are different sizes. I'm looking for the amperage rating of each relay. Anyone have a cross-reference or know someone that has a Rodeo? By the way, this came from the relay box under the hood, over the fender. It had to be a pre-1996 Rodeo.

Thanks guys!

 

i wouldn't put any more that 30A through them, thats what most relays of that size are rated for

 

Cool! That's what I was hoping for. It's still got me wondering though... If there are 3 different part numbers, could one be a 10amp, another a 20amp the other a 30amp? I wouldn't want to put 25 amps (just an example) through a 10 or 20amp relay and blow it, when I could have used it on something with a lighter load.

 

The different part numbers may also have to do with their state at rest (ie Normally Open or Normally Closed) Take a meter and do a continuity test of 30 to 87 and of 30 to 87a. That will tell youn some more about them.

30a is normally what you see iin automotive relays, but there are also lower and higher amperage units used - with these not having any markings I'd err on the side of caution.

You could call the Izusu parts department with the numbers to see if they have any additional info...

 

Google. Google. Google.

Check the PDF document from the 2nd hit. That part number shows up twice (page 245 & 271), each time showing it in a schematic where the load side of the relay is preceeded with a 20A fuse.

 

Note that in Bosch relays there are a bunch of different stypes available that look the same but with differences internally. Aside from the SPST and SPDT (the diagram in Jovis post would be a SPDT) that we all know so well, some have things like internal resistors or capacitors or quenching diodes for various specific uses etc. On Bosch brand relays it shows on the little diagram on the side of the relay. Other brands may not.
