what, a Lucas battery in a BMW? the british prince of darkness
I, I, I, didn't do it... he did it, the Seller did it!
Varta batteries still available here in CH;
when it fails
, I'll replace it!
Thanks Chris, very helpful!
Hmmm... one is not populated, but high beams work, and horn works...:confused: Easy enough to pull the relay and see which one stops working!
Seller said the right-hand empty socket was for an option I do not have. I assumed fog lamps.
I don't have the Owner's Manual at hand, but I don't recall that it actually identifies the relays around the vehicle. It
is great though, how much hands-on maintenance is described, and was assumed to be done by the driver. Very different form the "turn the key and go" experience of modern cars, and that's where the fun is!
Upon further investigation...
From the color diagram, it looks like the Horn and High Beams (ref "Fog Light Relay") are in that location. (Socket is just a tie-point connection for High Beams, hence High Beams work with an empty socket.)
The relays by the battery- high beam and horn are 4 pole relays
High Beams are solid color wires, therefore not fused, so I guess a relay harness in the High Beam circuit is in order as a future project!.
Hmmm. I guess I could break the connection at that socket, move black and white from 85 to 87, move white input to 30 (disconnect battery input), add a ground at 86, install a relay, and checkmate! I see a plan forming...
