Tach issues
Hi all
my tach was not working when I bought my car. It turns out the cable was shredded at the tach side, no biggie, swap the cable, right?
well I ordered a cable from corvette central hooked it up, which is I royal pain. The tach did not work. Upon further inspection the cable isn’t reaching the driven gear in the tach. I used the old cable to check to see if the gear in the tach works and it does, I also checked to see if the tach itself works and it does.
it seems the inner cable that actually spins isn’t long enough, I contacted the supplier and they sent another cable and it still doesn’t work.
could it be two bad cables or am I missing something? I was going to order a new cable from another supplier to try that but figured I’d see if anyone has any experience with this.
thx for any help

are they sending you a 23" cable with a screw on connection at the distributor and a push on connection at the tach?
how is your distributor clocked?
is the vacuum advance unit pointing towards the rear of the valve cover?
