Thanks for the responses everyone...

I'm at the end of my rope. After speaking to a knowledgeable tech at Crane Cams, we both have determined that most probably this tach is bad. However, the company that replaced the original workings of this older Smiths tach with brand new modern electronics, APT/Gaugeguys, has offered absolutley no help in this situation-and with ATTITUDE over the phone yet...I received the tach in the mail, hooked it up per instructions and $240.00 later-it doesn't climb above 1000RPM. I sent it back at my shipping expense, and 2 weeks later received it with no phone call or note enclosed as to what the problem was, and AGAIN it doesn't work. The people at APT said they can't do anything over the phone and need to see the tach again-becuase it was working perfectly when it left their shop. Huh? Did they even look at it when I sent it back? Thinking that the problem was on my end, I involved the Crane tech and troubleshooted with him for a day. EVERYTHING IS NORMAL ON MY END. The car starts and runs fine with the XR 3000 ignition and a PS 60 coil.

So people: let this be a warning to you all-don't trust just any company on the web for your vintage vehicle needs! I drilled a hole in my pristine 122 dash to mount this Smiths tach and I'm screwed...and out $240.00 plus double shipping.


Sorry about the ramblimg post but I feel I need to let this out somewhere...
