86 SDL, no power to power seats

[harrywat]

Where do I start? I get nothing on either seat with key on, running, door open and in or out of seat.

I have (part of) an "Electrical Troubleshooting manual " that covers 1986 through 1991. Its missing a bunch of pages in the first part but has diagrams that seem to cover my problem.

I'm confused (no kidding) that the manual shows a relay "H" in the fuse box, but in that location in my fuse box there are two red fuses. However, FYI this is one of the early models that did not have the external fuse 16 update. (but soon will)

I see fuses a, b, 15 and 17 along with a diode and the mystery relay are involved. I have replaced the fuses with no change.

Help if you can and please treat with kid gloves. You are dealing with an electrical ignoramus.

Thanks
Harry
