How much do any of those guys charge to fix a 2 part tach...Is it cheaper than $117? That would get you that zip bang electronic 21 century tach retrofit. Hate to have someone get their old sardine can fixed to stock specs for $80 and then find out it still can't read an MSD or electronic ignition.[/
Darn!!!! I did your tach test with "D" battery and sure enough the needle moved to just above the 2K mark and stayed there.This method works for the early console tachs that have an external sender...don't know if it works with dash tachs...
Test the tach with a "D" size battery...take yellow wire and touch "+" side of D-cell battery, take black wire and connect to "-" side of D-cell battery, needle should move to around 2,000 RPM and hold steady...if it does not move, it's dead

Kudos to you for the suggestion...Not sending the tach out for repair after all. I guess I'll order the RTE kit and give that a try.
