I finally figured out how the gauge cluster comes apart. I got the speedo out and Swapped in 10 LED lights. They were the $10 ten pack from amazon linked on some thread here about LED's. I'm happy with the results. It's a nice pale white illumination of the gauge cluster. It's kind of ghostly.
Got the voltage meter working again. Got the tach to show signs of life but it is way off. I don't think i'm shifting at 8k
I used about half a can of contact cleaner on the whole deal and scraped the contacts on the stubborn lights.
This is one of those, have to do it 4 times to get it right kind of jobs. Every time i put it back together i realized i goofed something up. forgot the turn signal green piece, take it apart again. forgot to test the turn signals, take it apart again. Tach stops reading, take it apart again.
Somehow I managed to only break 1 clip and a light socket this time. I'll have to do without the seatbelt warning. The whole assembly, every part of it is very brittle.
Temp and oil pressure sensors are still dead. I'm going to have to test those connections with a meter.
