So the gauge cluster was my first big sub unit that needed to be reworked and repaired. Here is the state of things before I started.
Cosmetically, it was in rough shape with most of the black paint gone from the gauge backs and the aluminum frame. Underneath it got worse, each of the center four indicator lights sits in a rubber tube that at some point had filled with water and caused the bulb and holder to rust away in some cases! Fortunately, there are several online suppliers that make many reproduction parts for this bike. So I ordered 3 new bulb holders and cut and soldered new bulb holders in place.

Here is a new holder along side one of the rusted out holders.
Here is the finished product reassembled, looking good. They do make reproduction face plates for the gauges and mine is slightly nicked up, but I like it that way and think I will keep it like that for now.
