Quick check, undo door harness and see if draw drops

Pete..you’ve picked up one weakness with current track type wiring diagrams like Volvo provides. Only the wiring appropriate for the subsection are shown I don’t see the yellow wire in the power distribution section, but it could be somewhere else, and unfortunately there is no way to see where to l...

For what it's worth, my '97 855 GLT also has the same yellow wire going to the positive battery terminal.

The yellow wire goes to the Secondary Air System. It supplies the power for the Secondary Air Relay and the Secondary Air pump. In the wiring diagrams you will find the yellow wire in the Engine Management and Sequential Fuel injection sections for Fenix 5.2. & Motronic 4.4. On the Motronic 4.3 ...

Do instead of cutting the wire , pull relay 2/53 and test to see if it is fused closed.

If it isn’t , your ECU is pulling the relay closed by fault.

You can solve the drain problem by just pulling the relay.

That will be an SAS code if you didn’t do the delete

So I dont if anyone has watched Roberts recent videos. He says he has a manufacturer that is willing to produce new R style front bumpers and possibly another manufacturer willing to make new leather seat covers for the p80 cars. He was asking for comments indicating interest for the manufacturer to...

Are you sure the diode is still ok? Should be I know but ...

I guess the relay could be further deteriorated and somehow tripping a code, that may be more likely.

But it also seems to sense around the relay if things are working (probably drawing current). P0410 does mean the current draw from the SAS relay is wrong. Could be too high (short) or too low (open). This test cannot detect a defective Air pump. ( If your scanner translation is correct ). If it is...

^ Then throw them back in the lake where they apparently came from. Seriously, I just can't believe the amount of rusted parts that I have seen posted here. I wish there was a way for a NE group buy of some sort to get replacement parts from this part of the country over to you guys in the rust zone...
