You're right. None of my gear tips apply because the speedometer cuts out. That's not the usual form of trouble folks have after replacing the gear.

There are more places for trouble to occur than just the L-shaped plug. Solder cracks can happen on the light components too, and in the case where neither odo nor speedo work, those are all that remain. And of course, the trouble could be external to the gauge. The same type (although larger versions) of connectors used in that temp faker board are used to pass and fuse power to the gauge. It is obviously a loose connection. Reference to "bad" electronics that acts up with mechanical influence is a synonym for "loose connection" always.
