[s-cars] inop tachometer/need new tach?

[AUDIJIM at aol.com]

I painstakingly re-soldered every soldered joint on both boards on my 
cluster. I sprayed some oxidation solvent on the connectors before installation. 
Started the car, the tach worked for a little while and I drove her around the 
block. It then stopped working. I saw it starting to fluctuate while I was at 
3000-3500 RPM (between shifts) and it then went to no indication at all. I think 
I can eliminate the boards at this point. If anyone has an S4 tach they are 
willing to part with, please let me know. I have a friend sending me an S6 
cluster to troubleshoot with, but I think at this point, I need a new tach.

Thanks,

Jim
