This is getting confused already:

1) On Sun May 25 15:50 EST you said: "Since the relays are identical I tried the tests and one had voltage (at terminal 87) and the other one didn't.". That must have been the System relay because that's the one that energizes when the Key is turned on, as proven by voltage at 87.

2) But now (still talking about the System relay) you say: "at terminal 86 there's a red wire, and at terminal 30 there's a larger red wire. This is in agreement with fig 13.1b except that the wire the red wire at terminal 30 doesn't jumper over to terminal 86. On my car these are two seperate wires. I even checked voltage and I have 12V at terminal 30 but no voltage at terminal 86."

Were you then missing +12V at System 87 with the Key On? In #1 above you had it, meaning there MUST have been voltage at 86 to energize the relay. But something must have changed if now (at #2) there is NO voltage at 86.

I suggest you do your voltage checks first at the relay's "output" terminal(s), to verify the "Picked" state, and leave the other terminals alone unless the relay doesn't pick as it should.

As to the relays themselves, it would help if you gave us the part numbers. Just saying that they are "different" only raises the possibility of problems but gives nothing to go on.

That said, we've gained little to this point except for one post #1 where the System Relay appears normal (voltage at 87), followed by post #2 where there is no voltage to energize the relay (at 86). With no mention of 87 in #2, we can only assume it failed this time. So which is it? System relay working or not?

And what are the relay part numbers?

The Bosch # should be 0 332 204 150 (others MAY swap OK but need # to verify)
The Volvo # is 1324070 (superseded by part number 872300)
