Well, my replacement screws from BoltDepot arrived and none of them fit. It turns out that the screws used on the steering indicator are narrow head M5 screws….. nearly unobtanium. WTF.
I found a company, Misumi USA that either stocks them or will make them and ship them for $3/ea. Done.
I also found a set of wiring diagrams for Neoplan USA on eBay. It’s a $50 gamble that it will shed some light on my bus.
The 24v flasher showed up and it actually works well. We’ll see if I wind up throwing it away when I convert the turn signals to 12v.
So much fun, so little time.
