Update on dash.
Well it looks like I need to find another dash. I removed it cleaned all contacts and reinstalled it. Checked all of the grounds and started it up - my dash worked!!! - for about 5 min. until it warmed up - ping and all guages (except the tach and speedo) go dead. Took it all out again and cleaned it and looked for bad solder joints. Put it back in, worked again for about 5 min.
This is the pattern it repeats now, when it is cold in the morning it works fine, as soon as it heats up they go dead. Bad component in a circuit card I assume.
