My bone stock ride
First order of business: dissect gauge cluster, repair dead odometer and replace the SI batteries.
Odometer gears did not mesh because the mechanism which is held in place by a peg broke its bracket. BMW plastics kinda get brittle after 20 years or so. Solution: Selleys epoxy cement. It's kinda like clay/plaster. Superglue back the bracket and re-inforce by building it up with cement.
SI batteries were a pain to get to. Buried in the innermost recesses of the gauge cluster. The meters sit on their own PCB. The SI has its own sub-PCB under the main one. The batteries are soldered in and sealed with glue. BMW kindly used lithium batteries but even those dont last forever. Solution: De-solder the tabs from the bottom of the PCB and cut thru the glue. I wired a remote battery pack, so next time the batteries need changing, I ain't doing this shit again.
