Tach repair
« on: March 15, 2025, 12:01:00 AM »
I'm looking for some guidance to get my 68 speedo and tic tok repaired . Is there any preferred specialty vendors for this ? I've got a very bouncy and noisy speedo and a tach that doesn't work with my pointless dist ! thanks

Speedo issue could be the cable. How did you determine the speedo is defective? Tach may need a filter if it worked with points and not HEI. Or you wired it incorrectly. Lot of rebuilders out there. Do a search, ask other people. I used Bob's Speedo once.

Instrument Services - in business since around 1979. 

They just finished the clock for my ‘66 Chevelle and did a quality job. Took about a month to get it back.

Thanks for the info, I have replaced the speedo cable and housing a couple times but speedo takes fits more so when cooler weather outside, it will jump from 10-100 and everything in between and sequels like crazy until I reach up and disconnect it .The tach has never worked even after replacing the burnt board on the back of the cluster never had a points dist in the car so I can't say if it worked with points or not but I have tried a filter with no success. I am going to hook up an aftermarket tach and see if it will work to determine if I'm getting a signal from the coil .
